Section 1 - General Information

Introduction About this Publication This publication is designed for the benefit of JCB Distributor Service Engineers who are receiving, or have received, training by JCB Technical Training Department.

All sections are listed on the front cover; tabbed divider cards align directly with individual sections on the front cover for rapid reference.

These personnel should have a sound knowledge of workshop practice, safety procedures, and general techniques associated with the maintenance and repair of hydraulic earthmoving equipment.

Where a torque setting is given as a single figure it may be varied by plus or minus 3%. Torque figures indicated are for dry threads, hence for lubricated threads may be reduced by one third.

Renewal of oil seals, gaskets, etc., and any component showing obvious signs of wear or damage is expected as a matter of course. It is expected that components will be cleaned and lubricated where appropriate, and that any opened hose or pipe connections will be blanked to prevent excessive loss of hydraulic fluid and ingress of dirt. Finally, please remember above all else SAFETY MUST COME FIRST!

'Left Hand' and 'Right Hand' are as viewed from the rear of the machine facing forwards.

The manual is compiled in sections, the first three are numbered and contain information as follows:

This Service Manual covers the following machines: 412S Wheeled Loading Shovel from machine serial number 535000 414S Wheeled Loading Shovel from machine serial number 537000 416S Wheeled Loading Shovel from machine serial number 543000

General Information - includes torque settings and service tools.

Care & Safety - includes warnings and cautions pertinent to aspects of workshop procedures etc.

The information provided in this manual for the 414S machine also applies to the 416S machine except where speciified.

Routine Maintenance - includes service schedules and recommended lubricants for all the machine.

Smoothshift Transmission introduced from the following serial numbers:

The remaining sections are alphabetically coded and deal with Dismantling, Overhaul etc. of specific components, for example:

412S Wheeled Loading Shovel from machine serial number 535500

Attachments

Body & Framework...etc.

414S Wheeled Loading Shovel from machine serial number 537300 416S Wheeled Loading Shovel from machine serial number 543100

The page numbering in each alphabetically coded section is not continuous. This allows for the insertion of new items in later issues of the manual.

JCB 444 Series engine added to 412S Wheeled Loading Shovel from machine serial number 1242000.

Section contents, technical data, circuit descriptions, operation descriptions etc. are inserted at the beginning of each alphabetically coded section.

Section 1 - General Information

Identifying your Machine Identification Plates Identification Plate Your machine has an identification plate 1X mounted on the left hand side of the machine on the loader arm pillar. The serial numbers of the machine and its major units are stamped on the plate.

identification plate, or simply stamp out the old number. This will prevent the wrong unit number being quoted when replacement parts are ordered. The machine and engine serial numbers can help identify exactly the type of equipment you have.

Unit Identification The engine serial number is stamped on a plate 2Y or 3Y which is fastened to the right side of the cylinder block, near the fuel filter. Note: For machines with the JCB 444 Series engine, see Section K, Technical Data.

Lubricants

The collection and disposal of used oil should be in accordance with any local regulations. Never pour used engine oil into sewers, drains or on the ground.

Introduction It is most important that you read and understand this information and the publications referred to. Make sure all your colleagues who are concerned with lubricants read it too.

Handling New Oil

Hygiene

There are no special precautions needed for the handling or use of new oil, beside the normal care and hygiene practices.

JCB lubricants are not a health risk when used properly for their intended purposes.

Used Oil

However, excessive or prolonged skin contact can remove the natural fats from your skin, causing dryness and irritation. Low viscosity oils are more likely to do this, so take special care when handling used oils, which might be diluted with fuel contamination. Whenever you are handling oil products you should maintain good standards of care and personal and plant hygiene. For details of these precautions we advise you to read the relevant publications issued by your local health authority, plus the following.

Used engine crankcase lubricants contain harmful contaminants. Here are precautions to protect your health when handling used engine oil: 1

Avoid prolonged, excessive or repeated skin contact with used oil.

Apply a barrier cream to the skin before handling used oil. Note the following when removing engine oil from skin: a

Storage

Wash your skin thoroughly with soap and water.

b Using a nail brush will help.

Always keep lubricants out of the reach of children.

Never store lubricants in open or unlabelled containers.

Use special hand cleansers to help clean dirty hands.

d Never use petrol, diesel fuel, or paraffin for washing.

Waste Disposal

!MCAUTION

Avoid skin contact with oil soaked clothing.

It is illegal to pollute drains, sewers or the ground. Clean up all spilt fluids and/or lubricants.

Don't keep oily rags in pockets.

Wash dirty clothing before re-use.

Throw away oil-soaked shoes.

Used fluids and/or lubricants, filters and contaminated materials must be disposed of in accordance with local regulations. Use authorised waste disposal sites. INT-3-2-14

All waste products should be disposed of in accordance with all the relevant regulations.

Section 3 - Maintenance Routine Maintenance Health and Safety First Aid - Oil Eyes In the case of eye contact, flush with water for 15 minutes. If irritation persists, get medical attention. Swallowing If oil is swallowed do not induce vomiting. Get medical advice. Skin In the case of excessive skin contact, wash with soap and water.

Spillage Absorb on sand or a locally approved brand of absorbent granules. Scrape up and remove to a chemical disposal area.

Fires

!MWARNING Do not use water to put out an oil fire. This will only spread it because oil floats on water. Extinguish oil and lubricant fires with carbon dioxide, dry chemical or foam. Fire fighters should use self contained breathing apparatus. 7-3-1-3_1

Section 3 - Maintenance Routine Maintenance Service Schedules

Service Schedules A badly maintained machine is a danger to the operator and the people working around him. Make sure that the regular maintenance and lubrication jobs listed in the service schedules are done to keep the machine in a safe and efficient working condition.

!MWARNING Maintenance Maintenance must be done by suitably qualified personnel. Before attempting any maintenance work, make sure the machine is safe. Park on level ground. If it is necessary to work with the loader arms raised, then the loader arm safety strut must be fitted as shown in Loader Arm Safety Strut in MAINTENANCE section. 2-3-1-1

Pre-start Cold Checks, Service Points and Fluid Levels

Apart from the daily jobs, the schedules are based on machine running hours. Keep a regular check on the hourmeter readings to correctly gauge service intervals.

Greasing

!MWARNING Make the machine safe before working underneath it. Park the machine on level ground and lower the attachments, (If it is necessary to work with the loader arms raised, then the loader arm safety strut must be fitted). See Loader Arm Safety Strut in MAINTENANCE section. Engage the park brake, put the transmission in neutral and stop the engine. Block both sides of all four wheels. If you are working near the articulation danger zone, fit the articulation safety lock. See Articulation Lock in MAINTENANCE section. 4-3-2-4_1

Bucket Pivot Points Total of 4 grease points (1-1 to 1-4)

Loader Arm Pivot Points Total of 20 grease points. (1-5 to 1-24) For interval see K Service Schedules ( T 3-12) The machine must be greased regularly to keep it working efficiently. Regular greasing will also increase the machine's working life. Grease should be applied with a grease gun, normally two strokes of the gun should be sufficient. Stop the greasing procedure when fresh grease appears at the joint. Use the recommended grease. See K Lubricants and Capacities - Pre-Smoothshift Transmission ( T 3-1). In the following illustrations, the grease points are numbered. Count off the grease points as you apply grease to each one. Refit the dust caps after greasing.

Note: Where low sulphur/low aromatic fuels are used it is important that lubricity additives are used. The additives listed below are advertised as being suitable for bringing the lubricity levels of kerosene/low sulphur fuels up to those of diesel fuels. They have not been tested or approved by the engine manufacturer. They should be added by your fuel supplier who should understand the concentration level necessary. 1

Elf 2S 1750. Dosage 1000-1500 ppm (0.1 - 0.15%), specifically for Indian Superior Kerosene (SKO) but may be applicable to other fuels.

Low Temperature Fuels

Consult your fuel supplier or JCB distributor about the suitability of any fuel you are unsure of. GEN-9-2

Acceptable Fuel Specification

!MCAUTION The fuel specification below is acceptable, however this fuel may reduce the life of the fuel injection equipment. The use of this fuel may also affect the engine performance.

Special winter fuels may be available for engine operation at temperatures below 0°C (32°F). These fuels have a lower viscosity. They also limit wax formation in the fuel at low temperatures. (Wax forming in the fuel can stop the fuel flowing through the filter.)

Section 3 - Maintenance Routine Maintenance Fuel System

Fuel Lift Pump An improved fuel lift pump has been introduced for use on JCB four-cylinder 1000 Series diesel engines. The new pump is a one piece assembly and cannot be dismantled. The new pump is interchangeable with the earlier pump. The procedure to remove and fit the new pump has not changed, see Engine Service Manual. Remove and clean fuel inlet strainer 38-2 when suspected blocked ie. low on power, difficult to start, fuel tank contamination.

Cleaning the Strainer 1

Allow the engine to cool. Remove the fuel filler cap to vent the system and reduce loss of fuel. Disconnect the fuel inlet pipe to the lift pump.

Unscrew the fuel filter 38-A. Remove strainer 38-2 and O-ring 38-3.

Clean the strainer in clean diesel fluid and dry with low pressure compressed air. Renew the strainer and O-ring if damaged.

Fit the strainer into the fuel inlet connection. Fit the inlet connector 38-A and tighten to 20Nm (15 lbf ft). Fit the fuel inlet pipe carefully to prevent damage to the strainer, and tighten the union nut.

Fig 38.

Important: The fuel strainer can be damaged and fuel flow can be restricted if the fuel pipe is inserted too far into the inlet connection. This should be checked if a fuel restriction is suspected. Make sure the olive on the fuel inlet pipe is in good condition and forms an effective seal. Renew the olive or pipe if necessary to prevent air entering the fuel system. 5

Fit the tank cap and prime the fuel system. Start the engine and check for fuel leakage.
