GENERAL SAFETY ESSENTIALS ACCESSORY APPLICATIONS The excavator has been pr imarily designed f or moving ear th with a b ucket. For use as a g rapple or f or other object handling, contact Dae woo f or proper installation and application. Lifting-w ork applications (unless restr icted or prohibited b y local regulations) are per mitted in appro ved lift configu ation, to r ated capacity only, with no side-loading. DO NOT use the machine f or activities f or which it w as not intended. DO NOT use the bucket for lifting work, unless lift slings are used in the approved configu ation. Use of an accessor y hydraulic hammer (break er), work in rough terr ain, demolition applications or other hazardous operation may require installation of additional protective structures to safeguard the operator. LIFTING CAPACITY RATING CONFIGURATION Lifting capacity r atings that are pr inted at the end of this saf ety section are based on the machine being level, on a fi m supporting surface, with hooks and slings attached in appro ved configu ation. Loads must be balanced and suppor ted e venly. Use taglines to k eep the load steady if wind conditions and large surface area are a prob lem. Work crew hand signals , individual tasks and saf e procedures should all be universally understood before the lift is made.

IMPORTANT Before using the excavator to make lifts check municipal and regional regulations or statutes that could apply. Governing ordinances may require that all heavy lifting be done with single purpose equipment specifically designed for making lifts, or other local restrictions may apply. Making heavy lifts with a general purpose excavator that can be used for digging, loading, grading or other work may be expressly forbidden by a regional injunction or other legal prohibition. Always follow all of the other instructions, guidelines and restrictions for Safe Lifting in the Operation and Maintenance Manuals.

SUMMARY OF SAFETY PRECAUTIONS FOR LIFTING IN DIGGING MODE DANGER! Unsafe use of the excavator while making rated lifts could cause serious, potentially fatal injuries or extensive damage to the machine or nearby property. Do not let anyone operate the machine unless they’ve been properly trained and understand the information in the Operation and Maintenance Manual. To lift safely while in Digging Mode, the following items must be evaluated by the operator and the work site crew. •

Condition of ground support.

Excavator configu ation and attachments.

Weight, lifting height and lifting radius.

Safe rigging of the load.

Proper handling of the suspended load.

Taglines on opposite sides of the load can be v ery helpful in keeping a suspended load secure, if they are anchored safely to control points on the ground.

WARNING! NEVER wrap a tagline around your hands or body. NEVER rely on taglines or make rated lifts when wind gusts are more than 48.3 km/hr (30 mi/h). Be prepared for any type of wind gust when working with loads that have a large surface area. Always engage the "Digging Mode" control on the Instr ument Panel before using the excavator for lifting work.

WARNING! If you need more information or have any questions or concerns about safe operating procedures or working the excavator correctly in a particular application or in the specific conditions of your individual operating environment, please consult your local Daewoo representative. UNAUTHORIZED MODIFICATIONS Any modification made without autho ization or written approval from Daewoo can create a safety hazard, for which the machine owner must be held responsible. For safety’s sake, replace all OEM parts with the correct authorized or genuine Daewoo part. For example, not taking the time to replace f asteners, bolts or n uts with the correct replacement par ts could lead to a condition in which the safety of critical assemblies is dangerously compromised.

WORK SITE PRECAUTIONS ATTACHMENT PRECAUTIONS Options kits are a vailable through y our dealer . Contact Dae woo f or inf ormation on a vailable one-w ay (single-acting) and tw o-way (double-acting) piping/valving/auxiliary control kits . Because Dae woo cannot anticipate, identify or test all of the attachments that o wners may wish to install on their machines , please contact Daewoo for authorization and approval of attachments, and their compatibility with options kits. AVOID HIGH-VOLTAGE CABLES Serious injur y or death can result from contact or pro ximity to high-v oltage electr ic lines . The bucket does not ha ve to mak e physical contact with power lines for current to be transmitted. Use a spotter and hand signals to sta y a way from po wer lines not clear ly visib le to the operator. VOLTAGE

Figure 1

Use these minimum distances as a guideline only. Depending upon the voltage in the line and atmospheric conditions, strong current shocks can occur with the boom or bucket as far away as 4 - 6 m (13 - 20 ft) from the power line. Very high voltage and rainy weather could further decrease that safety margin. NOTE:

Before star ting an y type of oper ation near po wer lines (either abo ve g round or b uried cable-type), you should always contact the power utility directly and work out a safety plan with them.

BEFORE STARTING TO DIG, CONTACT AUTHORITIES Below ground hazards also include natur al gas lines, water mains, tunnels and b uried foundations. Know what’s underneath the work site before starting to dig. BE AWARE OF HEIGHT OBSTACLES Any type of object in the vicinity of the boom could represent a potential hazard, or cause the oper ator to react suddenly and cause an accident. Use a spotter or signal person w orking near br idges, phone lines, work site scaffolds, or other obstructions.

S0102000 Page 7


Return to Master Table of Contents USE CARE ON LOOSE SUPPORT Working heavy loads o ver loose, soft g round or une ven, broken terr ain can cause dangerous side load conditions and possible tipover and injury. Travel without a load or balanced load may also be hazardous. If temperatures are changing, be cautious of dar k and wet patches when w orking or traveling over frozen ground. Sta y a way from ditches , o verhangs and all other w eak suppor t surf aces. Halt w ork and install support mats or blocking if work is required in an area of poor track support. USE SOLID SUPPORT BLOCKING Never rely on lift jacks or other inadequate suppor ts when work is being done. Block tracks fore and aft to prevent any movement. OVERHANGS ARE DANGEROUS Digging the w orkface under an o verhang - the w ork area beneath a cliff or under the edge of a ditch - is dangerous. Kno w the height and reach limits of the e xcavator and plan ahead while w orking. A void creating dangerous situations by moving around the work site while making excavations. Go onto another digging area bef ore steep o verhangs are f ormed. Working around deep pits or along high w alls or trenching ma y require suppor t b locks, especially after hea vy r ainfalls or dur ing spr ing tha ws. P ark the excavator away from overhangs before work shut down. SLOPING TERRAIN REQUIRES CAUTION Dig e venly around the w ork site whene ver possible, tr ying to g radually le vel an y e xisting slope. If it’ s not possib le to le vel the area or avoid working on a slope, reducing the size and cycling rate of the workload is recommended. On sloping surf aces, use caution when positioning the excavator before starting a w ork cycle. Stay alert for instability situations to avoid getting into them. F or e xample, y ou should always a void w orking the b ucket o ver do wnhill crawler tracks when parked perpendicular to the slope. Slo w all do wnhill s wing mo vements and avoid full e xtensions of the b ucket in a do wnhill direction. Lifting the bucket too high, too close to the machine, while the excavator is turned uphill can also be hazardous.

Figure 7 ASBESTOS DUST HAZARD PREVENTION

Asbestos dust can be HAZARDOUS to your health if it is inhaled.

If you handle materials containing asbestos fiber , follow these guidelines as given below: •

Never use compressed air for cleaning.

Use water for cleaning to keep down the dust.

Work on the machine or component with the wind at your back whenever possible.

Use an approved respirator with proper filt ation.

TAKE TIME TO PROVIDE GOOD VISIBILITY Halt w ork if visibility is poor . Strong r ains, sno w, f og and e xtremely dusty conditions can all obscure visibility so badly that it is best to wait for weather to change or dust to settle before continuing operation. Night work in areas of limited visibility should be halted if installation of extra work lights on the machine (or work area) is necessary. Keep dirt and dust off of windows and off the lens surfaces of work lights. Stop working if lights, windows or mirrors need cleaning or adjustment.

TRAVEL PRECAUTIONS Attachment control levers should not be operated while traveling. Do not change selected travel mode (FAST/SLOW) while traveling. Fold in w ork equipment so that the outer end of the boom is as close to the machine as possib le, and is 200 mm - 300 mm (8" - 12") above ground. Never travel over obstacles or slopes that will cause the machine to tilt se verely. Travel around an y slope or obstacle that causes 10 degrees tilt, or more. OPERATE CAREFULLY ON SNOW AND ICE AND IN VERY COLD TEMPERATURES In icy cold w eather a void sudden tr avel mo vements and sta y a way from e ven v ery slight slopes . The machine could skid off to one side very easily. Snow accumulation could hide or obscure potential hazards . Use care while oper ating or while using the machine to clear snow. Warming up the engine f or a shor t period may be necessar y, to avoid operating with sluggish or reduced working capacity. The jolting shoc ks and impact loads caused b y b umping or bottoming the boom or attachment are more likely to cause severe stress in very cold temperatures. Reducing work cycle rate and work load may be necessary. PARKING THE MACHINE Avoid making sudden stops, or parking the machine wherever it happens to be at the end of the w ork day. Plan ahead so that the e xcavator will be on a fi m, level surface a way from tr affic and way from high walls, cliff edges and an y area of potential w ater accum ulation or r unoff. If par king on inclines is unavoidable, block the crawler tracks to prevent movement. Lower the bucket or other working attachment completely to the g round, or to an o vernight support saddle. There should be no possibility of unintended or accidental movement.

TEST CONDITIONS 1.

All tests should be performed on a flat, l vel, fi mly supporting ground surface.

2.

All recommended, applicab le maintenance and adjustment ser vice should be completed pr ior to testing.

3.

Hydraulic fluid and engine oil should be of approp iate viscosity f or ambient w eather conditions . Warm up hydraulic oil to standard operating temperature, between 45째 - 55째C (112째 - 135째F).

4.

Run all tests with the engine speed control set to maximum RPM.

5.

Repeat tests with Power Mode engine control settings at both P ower Mode II (standard w ork mode) and Power Mode III (high speed mode). Travel speed tests should also be repeated at both high and low speed.

TRAVEL SPEED AND TRAVEL MOTOR BALANCE (STEERING DEVIATION) TESTS Speed Test Prepare the excavator for travel speed tests by extending all hydraulic cylinders - boom, ar m and bucket to the fully extended position, shown in Figure 5.

0.3 M - 0.5 M (1' - 2') ARS1480L

Figure 5 The lowest part of the bucket linkage should be 0.3 - 0.5 m (1' - 2') off the ground. Mark off a 20 m (65' 7-1/2") test distance, with a 3 - 5 m (10' - 15') r un-up area, and a 3 - 5 m (10' - 15', or longer) speed run-off distance. Travel the excavator back and forth to be sure steer ing is centered and side fr ames are perfectly parallel with the test course. Operate both travel levers at the fully engaged position and measure the time it takes to cross 20 m (65' 71/2"). Compare measured results against the standard for new machines:

Figure 7 Extend the b ucket cylinder completely and retr act the ar m cylinder, as sho wn in Figure 7, to test s wing speed. The lowest point of the bucket will be approximately 1.5 m (3') off the ground. Use paint mar ks at the same point on the tur ntable and undercarr iage, or select alter nate measur ing locations and use a stopw atch to time 3 full 360° rotations . The time required f or 3 revolutions should be between 15.5 and 17.5 seconds in Power Mode II, 15.5 and 17.5 seconds in Power Mode III. Swing Force Test With the boom, ar m and b ucket in the same position as f or the s wing speed test, rotate the turntable so that the boom is e venly centered between the side fr ames, pointing str aight ahead. Locate the 90° ref erence point, perpendicular to the boom. Mar k the tur ntable and undercarriage with paint at the 90° point.

WELDING PRECAUTIONS AND GUIDELINES IMPORTANT To avoid accidents, personal injury and the possibility of causing damage to the machine or to components, welding must only be performed by properly trained and qualified personnel, who possess the correct certification (when required) for the specific welding fabrication or specialized repair being performed.

WARNING! Structural elements of the machine may be built from a variety of steels. These could contain unique alloys or may have been heat treated to obtain particular strength characteristics. It is extremely important that welding repairs on these types of steel are performed with the proper procedures and equipment. If repairs are performed incorrectly, structural weakening or other damage to the machine (that is not always readily visible) could be caused. Always consult Daewoo After Sales Service before welding on integral components (loader arm, frames, car body, track frames, turntable, attachment, etc.) of the machine. It is possible that some types of structurally critical repairs may require Magnetic Particle or Liquid Penetrant testing, to make sure there are no hidden cracks or damage, before the machine can be returned to service.

CAUTION! Always perform welding procedures with the proper safety equipment on hand. Adequate ventilation and a dry work area are absolutely essential. Keep a fire extinguisher nearby and always wear protective clothing and the recommended type of eye protection.

General Maintenance Procedures

S0302000 Page 3


Return to Master Table of Contents

CAUTION! Observe the following safety precautions: 1.

Use extra caution and adequate safety shielding when welding near fuel and oil tanks, batteries, hydraulic piping lines or other fire hazards.

2.

Never weld when the engine is running. Battery cables must be disconnected before the welding procedure is started.

3.

Never weld on a wet or damp surface. The presence of moisture causes hydrogen embrittlement and structural weakening of the weld.

4.

If welding procedures are being performed near cylinder rods, operator’s cab window areas or any other assemblies that could be damaged by weld spatters, use adequate shielding protection in front of the assembly.

5.

During equipment setup, always attach ground cables directly to the area or component being welded to prevent arcing through bearings, bushings, or spacers.

6.

Always use correct welding rods for the type of weld being performed and observe recommended precautions and time constraints. AWS Class E7018 welding rods for low alloy to medium carbon steel must be used within two hours after removal from a freshly opened container. Class E11018G welding rods for T-1 and other higher strength steel must be used within 1/2 hour.

HYDRAULIC SYSTEM - GENERAL PRECAUTIONS Always maintain oil le vel in the system at recommended le vels. Assemb lies that oper ate under hea vy loads, at high speed, with e xtremely precise dimensional toler ances between moving par ts - pistons and cylinders, or shoes and swash plates, for example - can be severely damaged if oil supply runs dry. Assemblies can be r un dr y and damaged se verely in a v ery shor t time when piping or hoses are disconnected to repair leaks and/or replace damaged components . Hoses that are inadv ertently switched during disassembly (inlet for outlet and vice v ersa), air introduced into the system or assemb lies that are low on oil due to neglect or careless maintenance, could all produce sufficient fluid loss to cause dama . When star ting the engine (par ticularly after long la yoff or stor age inter vals), make sure that all h ydraulic controls and operating circuits are in neutr al, or "OFF." That will prevent pumps or other components that may be temporarily oil-starved from being run under a load. Replacement of an y h ydraulic system component could require thorough cleaning, flushing, and som amount of pre-filling with fresh, clean oil if the protecti e seal on replacement par ts has ob viously been broken or if seal integ rity ma y ha ve been compromised. When protectiv e seals are remo ved bef ore installation and reassemb ly, inspect all replacement par ts carefully , bef ore the y are installed. If the replacement par t is bone dr y (with no tr ace of f actory pre-lube) or has been contaminated b y dir t or b y questionable oils, flushing and pre-filling with clean ydraulic fluid is recommended Vibration, irregular or difficult m vement or unusual noise from an y part of the h ydraulic system could be an indication of air in the system (and many other types of problems). As a general precaution (and to help minimize the risk of potential long-term damage), allow the engine to run at no-load idle speed immediately after initial star t-up. Hydr aulic fluid will circulat , releasing an y air that ma y ha ve been tr apped in the system before load demands are imposed. A daily w alk-around pre-star t equipment saf ety inspection, including a quic k visual scan f or any exterior evidence of leaking hydraulic fluid, can help xtend the service life of system components.

IMPORTANT Hydraulic system operating conditions (repetitive cycling, heavy work loads, fluid circulating under high pressure) make it extremely critical that dust, grit or any other type of contamination be kept out of the system. Observe fluid and filter change maintenance interval recommendations and always pre-clean any exterior surface of the system before it is exposed to air. For example, the reservoir filler cap and neck area, hoses that have to be disassembled, and the covers and external surfaces of filter canisters should all be cleaned before disassembly.

MAINTENANCE SERVICE AND REPAIR PROCEDURE GENERAL PRECAUTIONS Fluid level and condition should alw ays be chec ked whenever any other type of maintenance ser vice or repair is being performed. NOTE:

If the unit is being used in an e xtreme temperature environment (in sub-freezing climates or in high temper ature, high humidity tropical conditions), frequent purging of moisture condensation from the hydraulic reservoir drain tap should be a regular and frequent par t of the oper ating routine . In more moder ate, temper ate climates , dr aining reser voir sediment and moisture may not be required more than once or twice every few months.

Inspect drained oil and used filters or signs of abnormal coloring or visible fluid contamination at very oil change. Abr asive g rit or dust par ticles will cause discolor ation and dar kening of the fluid Visible accumulations of dirt or grit could be an indication that filter elements are verloaded (and will require more frequent replacement) or that disinteg rating bear ings or other component f ailures in the h ydraulic circuit may be imminent or ha ve already occurred. Open the dr ain plugs on the main pump casings and chec k and compare drain oil in the pumps. Look for evidence of grit or metallic particles. Vibration or unusual noise during operation could be an indication of air leaking into the circuit (Refer to the appropriate Troubleshooting section f or component or unit f or procedures .), or it ma y be e vidence of a defective pump. The gear-type pilot pump could be def ective, causing low pilot pressure, or a main pump broken shoe or piston could be responsible. NOTE:

If equipped, indicated oper ating pressure, as sho wn on the m ultidisplay digital gauge on the Instr ument P anel ("F-Pump" and "R-Pump") will be reduced as a result of a mechanical prob lem inside the pump . Ho wever, pressure loss could also be due to cavitation or air leakage, or other faults in the hydraulic system.

Check the exterior case drain oil in the main pumps . If no metallic par ticles are found, make sure there is no air in the system. Unbolt and remove the tank return drain line from the top part of the swing motor, both travel motors and each main pump . If there is air in an y one of the dr ain lines , carefully pre-fill th assembly before bolting together the drain line piping connections. Run the system at low rpm.

HYDRAULIC SYSTEM CLEANLINESS AND OIL LEAKS MAINTENANCE PRECAUTIONS FOR HYDRAULIC SYSTEM SERVICE Whenever maintenance , repairs or an y other type of troub leshooting or ser vice is being perf ormed, it’s important to remember that the h ydraulic system - including both the inter ior and e xterior surf aces of assemblies, and every drop of operating fluid - ust be protected from contamination. Dust and other f oreign contaminants are major contr ibutors to premature w ear in h ydraulic circuits. The narrow tolerances, rapidly moving par ts and high oper ating pressures of the system require that fluid b kept as clean as possib le. The perf ormance and dependability of the machine (and the ser vice lift of individual components) can be noticeably reduced if proper precautions are not observed: •

Use a saf e, non-comb ustible, e vaporative-type, lo w-residue solv ent and thoroughly clean exterior surfaces of assemblies before any part of the circuit is opened up or disassembled.

NOTE:

It’s just as impor tant to clean the cap and reser voir top bef ore routine fluid changes o quick chec ks as it is bef ore major repairs . (Accum ulated dir t attr acts moisture , oil and other fluids - and more di t.)

Keep dismantled parts covered during disassembly. Use clean caps, plugs or tape to protect the disconnected openings of flange , manifolds and piping.

Do not allow cleaning solvents or other fluids to mix with the oil in the system Use clean oil to flush a y traces of solvent or other residue before reassembly.

If metal or r ubber fragments are f ound in the system, flush and replace all fluid in the syst and troubleshoot the circuit to identify the source of contamination.

IMPORTANT Make sure that cleaning solvents will be compatible with rubber materials used in the hydraulic system. Many petroleum based compounds can cause swelling, softening, or other deterioration of system sealing elements, such as O-rings, caps and other seals. OIL LEAKAGE PRECAUTIONS Oil that is visibly seeping from joints or seals should always serve as a "red flag" ala m. Leaks must alert the machine oper ator and maintenance cre w that air, water and dir t have an open, free passageway through which to enter the circuit. Harsh, corrosiv e salt air , freezing and tha wing condensation cycles and working environments that are full of fine dust are especially hazardou . Clogging of valve spools or e xternal piping (especially pilot circuit piping) can g radually diminish or v ery suddenly put a complete stop to normal hydraulic function. You can prevent having to make these types of repairs by following recommended assembly procedures: 1.

Use new O-rings and oil seals whenever hydraulic assemblies are rebuilt.

2.

Prepare joint surf aces before assembly by checking alignment and flatnes . Clean and repair corrosion or any other damage.

3.

Follow bolt torque recommendations and all other assembly requirements.

CLEANING AND INSPECTION GENERAL GUIDELINES All parts must be clean to permit an effective inspection. During assembly, it is very important that no dirt or foreign material enters unit being assemb led. Even minute particles can cause malfunction of close fittin parts such as thrust bearing, matched parts, etc.

WARNING! Care should be exercised to avoid inhalation of vapors, exposure to skin and creating fire hazards when using solvent type cleaners. 1.

Clean all metal par ts thoroughly using a suitab le cleaning fluid It is recommended that par ts be immersed in cleaning fluid and m ved up and do wn slo wly until all oils , lubr icants, and/or f oreign materials are dissolved and parts are thoroughly clean.

2.

For bear ings that can be remo ved, soak them in a suitab le cleaning fluid or a min ute or tw o, then remove bear ings from cleaning fluid and st ike flat against a lock of w ood to dislodge solidifie particles of lubr icant. Immerse again in cleaning fluid to flush out p ticles. Repeat abo ve operation until bearings are thoroughly clean. To dry bearings, use moisture-free compressed air. Be careful to direct air stream across bear ing to a void spinning bear ings that are not lubr icated. DO NO T SPIN BEARINGS WHEN DRYING; bearings may be rotated slowly by hand to facilitate drying process.

3.

Carefully inspect all bear ing rollers , cages and cups f or w ear, chipping or nic ks to deter mine condition. Do not replace a bear ing cone or cup individually without replacing mating cup or cone at the same time . After inspection, dip bear ings in light w eight oil and wr ap in clean lintless cloth or paper to protect them until installation. For those bear ings that are to be inspected in place; inspect bear ings f or roughness of rotation, scoring, pitting, cr acked or chipped r aces. If an y of these def ects are f ound, replace bear ings. Also inspect defective bearing housing and/or shaft f or grooved, galled or b urred conditions that indicate bearing has been turning in its housing or on its shaft.

4.

It is more economical to replace oil seals, O-rings, sealing rings, gaskets and snap rings when unit is disassembled than w aiting for premature f ailures; refer to latest Micro Fiche and/or P arts Book f or replacement items . Be e xtremely careful when installing sealing members , to a void cutting or

Apply a thin coat of Loctite #120 to outer diameter, of metal casing, on oil seals to assure an oil tight fit into retaine. Use extreme care not to get Loctite on lips of oil seals . If this happens , that por tion of the seal will become br ittle and allow leakage. When replacing lip type seals, make sure spring loaded side is towards oil to be sealed. 5.

If available, use magna-flux or similar process or checking for cracks that are not visib le to the e ye. Examine teeth on all gears carefully f or wear, pitting, chipping, nic ks, cracks or scores . Replace all gears sho wing cr acks or spots where case hardening has w orn through. Small nic ks ma y be removed with suitab le hone. Inspect shafts and quills to mak e cer tain they have not been spr ung, bent, or splines twisted, and that shafts are true. NOTE:

Spline w ear is not considered detr imental e xcept where it aff ects tightness of splined parts.

Inspect thr ust washers for distor tion, scores, burs, and w ear. Replace thr ust washer if def ective or worn. 6.

Inspect bores and bearing surfaces of cast parts and machined surfaces for scratches, wear, grooves and dir t. Remo ve an y scr atches and b urrs with crocus cloth. Remo ve foreign matter. Replace an y parts that are deeply grooved or scratched which would affect their operation.

BEARING INSPECTION The conditions of the bear ing are vital to the smooth and efficient ope ation of the machiner y. When any component containing bear ings is disassemb led, always carefully e xamine the condition of the bear ings and all of its components for wear and damage. Once the bearing is removed, clean all parts thoroughly using a suitable cleaning solution. If the bearing is excessively dir ty soak the bear ing assemb ly in a light solution and mo ve the bear ing around until all lubricants and or foreign materials are dissolved and the parts are thoroughly clean. When dr ying bear ings, moisture free compressed air can be used. Be careful not to direct the air in a direction which will force the bearing to dry spin while not being properly lubricated. After the bear ings have been cleaned and dr ied, carefully inspect all bear ing rollers, cages and cups f or wear, chipping or nic ks. If the bear ing cannot be remo ved and is to be inspected in place , chec k f oe roughness of rotation, scor ing, pitting, cracked or chipped races. If any of these defects are found replace the whole bear ing assembly. NEVER replace the bear ing alone without replacing the mating cup or the cone at the same time. After inspection lightly coat the bearing and related parts with oil and wrap in a clean lintless cloth or paper and protect them from moisture and other foreign materials until installation. It is also important to inspect the bearing housing and/or shaft for grooved, galled or burred conditions that indicate that the bearing has been turning in its housing or on its shaft. If available, use magna-flux or similar process or checking for cracks that are not visible to the naked eye. The following illustrations will aid in identifying and diagnosing some of the bearing related problems. NOTE:

TORQUE WRENCH EXTENSION TOOLS Very large diameter , high g rade fasteners (n uts, bolts , cap scre ws, etc.) require a g reat deal of tur ning force to achieve recommended tightening torque values. Common problems that could occur as a result are: •

Recommended torque exceeds the measuring capacity of the torque wrench.

Specialized sockets do not fit the adapter on the front end (nose) of the torque wrench

Generating adequate force on the back end (handle) of the wrench is difficult or impossi le.

Restricted access or an obstruction may make use of the torque wrench impossible.

A unique application requires fabrication of an adapter or other special extension.

Most standard torque wrenches can be adapted to suit an y one of the proceeding needs or situations , if the right extension tool is used or fabricated. TORQUE MULTIPLICATION A wrench e xtension tool can be used to increase the tightening f orce on a high capacity nut or bolt. For example, doubling the distance between the bolt and the bac k (handle) end of the torque wrench doubles the tightening force on the bolt. It also halves the indicated reading on the scale or dial of the torque wrench. To accur ately adjust or con vert indicated scale or dial readings, use the following formula: I = A x T / A + B where: I = Indicated f orce shown on the torque wrench scale or dial.

Figure 1

T = Tightening force applied to the nut or bolt (actual Torque). A = Length of the torque wrench (between the center of the nut or bolt and the center of the handle). B = Length of the extension. As an e xample, if a 12" e xtension is added to a 12" torque wrench, and the indicated torque on the dial reads "150 ft lb," the real force applied to the bolt is 300 ft lb:

I= NOTE:

AxT A+B

=

12 x 300 12 + 12

=

3600 24

= 150

The formula assumes that there is no added deflection or "gi e" in the joint betw een the extension and torque wrench. Readings may also be inaccurate:

If the extension itself absorbs some of the tightening force and starts to bend or bow out.

If an e xtension has to be f abricated that is not perf ectly str aight (f or e xample, an e xtension made to go around an obstr uction, to allo w access to a difficult to tighten astener), the materials and methods used must be solid enough to transmit full tightening torque.

Return to Master Table of Contents OTHER USES FOR TORQUE WRENCH EXTENSION TOOLS Torque wrench e xtensions are sometimes made up f fastener.

or reasons other than increasing le

verage on a

For example, a torque wrench and e xtension can be used to measure adjustment "tightness" of a linkage or assemb ly. Specially f abricated e xtensions can be used to mak e v ery precise chec ks of the f orce required to engage or disengage a clutch mechanism, release a spr ing-applied brake assembly, or "tak e up" free play in most any movable linkage. Once the v alue of the adjustment f orce is estab lished, repeated chec ks at regular inter vals can help to monitor and maintain peak oper ating efficienc . These types of adjustment chec ks are especially useful if physical measurements of linkage tr avel are difficult to ma e or will not pro vide the needed deg ree of precision and accuracy. To allow the assembly or mechanism to accept a torque wrench, welding a nut or other adapter on the end of a linkage shaft or other leverage point will allow turning the shaft or assembly manually. TIGHTENING TORQUE SPECIFICATIONS (METRIC) (For coated threads, prelubricated assemblies.)

CAUTION! Disassembly, overhaul and replacement of components on the machine, installation of new or replacement parts and/or other service-related maintenance may require the use of thread or flange sealing assembly compound. Use the information on this page as a general guide in selecting specific formulas that will meet the particular requirements of individual assembly installations. Daewoo does not specifically endorse a specific manufacturer or brand name but the following table of "Loctite" applications is included for which cross-references to other makers’ products should also be widely available.

IMPORTANT Use primer "T" or "N" for all cold weather assembly of fastener adhesives, with Thread locker sealers 222, 242/243, 262, 271, 272, or 277.
