Introduction This publication is designed for the benefit of JCB Distributor Service Engineers who are receiving, or have received, training by JCB Technical Training Department. 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. 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! The manual is compiled in sections, the first three are numbered and contain information as follows: 1 2 3

= = =

General Information - includes torque settings and service tools. Care & Safety - includes warnings and cautions pertinent to aspects of workshop procedures etc. Routine Maintenance - includes service schedules and recommended lubricants for all the machine.

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

= =

Attachments Body & Framework

...etc.

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. Section contents, technical data, circuit descriptions, operation descriptions etc are inserted at the beginning of each alphabetically coded section. READ the section contents to locate machine types, machine type indentification IS NOT listed on individual pages. All sections are listed on the front cover; tabbed divider cards align directly with individual sections on the front cover for rapid reference. 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. 'Left Hand' and 'Right Hand' are as viewed from the rear of the machine facing forwards.

This Service Manual covers the following machines: 504B - from Machine Serial Number 277001 *526 - from Machine Serial Number 279289

Identification Plate

Unit Identification

Your machine has an identification plate V mounted as shown. The serial numbers of the machine and its major units are stamped on the plate.

The engine serial number is stamped on a label W which is fastened to the right side of the cylinder block, near the fuel filter.

504B F G F 500 Series machine range G 4,000 lbs lift capacity The serial number of each major unit is also stamped on the unit itself. If a major unit is replaced by a new one, the serial number on the identification plate will be wrong. Either stamp the new number of the unit on the 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.

Care & Safety

Section 2

Lubricants - Health and Safety

3-1

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

2

Apply a barrier cream to the skin before handling used engine oil.

However, excessive or prolonged skin contact can remove the natural fats from your skin, causing dryness and irritation.

3

Note the following when removing engine oil from skin: a Wash your skin thoroughly with soap and water. b

Low viscosity oils are more likely to do this, so take special care when handling used oils, which might be diluted with fuel contamination.

Using a nail brush will help.

c Use special hand cleansers to help clean dirty hands.

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.

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

Avoid skin contact with oil soaked clothing.

f

Don't keep oily rags in pockets.

g

Wash dirty clothing before re-use.

h

Throw away oil-soaked shoes.

Storage Always keep lubricants out of the reach of children. Never store lubricants in open or unlabelled containers.

First Aid - Oil

Waste Disposal Eyes All waste products should be disposed of in accordance with all the relevant regulations. The collection and disposal of used engine oil should be in accordance with any local regulations. Never pour used engine oil into sewers, drains or on the ground.

In the case of eye contact, flush with water for 15 minutes. If irritation persists, get medical attention. Swallowing

Handling

If oil is swallowed do not induce vomiting. Get medical advice.

New Oil

Skin

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

In the case of excessive skin contact, wash with soap and water.

Used Oil 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 engine oils.

9803/3610

Spillage Absorb on sand or a locally approved brand of absorbent granules. Scrape up and remove to a chemical disposal area. Fires Extinguish with carbon dioxide, dry chemical or foam extinguishers. Do not use water. Fire-fighters should use self-contained breathing apparatus.

Routine Maintenance Lubricants & Capacities

Section 3 1-1

New Engines New engines DO NOT require a running-in period. The engine/machine should be used in a normal work cycle immediately; glazing of the piston cylinder bores, resulting in excessive oil consumption, could occur if the engine is gently run-in. Under no circumstances should the engine be allowed to idle for extended periods; (e.g. warming up without load). Engines of new machines are filled at the factory with JCB 10W/30 Multigrade oil. This oil should be drained after the first 100 hours operation and the engine filled with the appropriate recommended grade as shown in the lubrication chart. JCB 10W/30 Multigrade should also be used for the first 100 hours operation whenever a new or reconditioned engine is fitted to the machine. After the first 100 hours operation, it is essential that the 10W/30 oil is replaced by the lubricant recommended in the lubrication charts.

*

Lubrication Charts Lubrication charts are included on the following pages for all machine models. Be sure you identify the machine and its lubricant requirements correctly.

(1)

In arduous conditions (eg. refuse re-handling, waste paper reclamation etc.) change the oil after every 250 hours or three months (whichever comes first).

(2)

After a major transmission repair, the new oil should be run to operating temperature and changed again to remove any contamination which entered during the repair. Change the oil and filter after a further 100 hours if the oil was heavily contaminated because of, or from the failure (eg. water contamination).

(3)

After a major transmission repair, the new oil should be run to operating temperature and changed again to remove any contamination which entered during the repair. Change the oil again after a further 100 hours to remove bedding-in wear. This is particularly important if new brake plates have been fitted.

Note: Jobs which should be done by a specialist are shown by †. First 100 hour service only (and after major re-builds), to be completed by JCB Distributor.
