Publication No. 9803/3140 Issue 4
,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.
It is assumed that these personnel have a sound knowledge of workshop practice, safety procedures and general
techniques associated with the maintenance and repair of hydraulic earthmoving equipment. Therefore, these basic
subjects generally are omitted from this manual, the intention being to convey only more specialised information
concerning particular aspects of a machine or component.
For example, renewal of oil seals, gaskets etc., and any component showing obvious signs of wear or damage is
expected as a matter of course and, therefore, information of this nature is included only in the context of specialised
procedures or where a range of wear tolerances is required. Similarly, it is expected that components will be cleaned
and lubricated where appropriate, also 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 SAFETY MUST COME FIRST!
The manual is compiled in sections, the first three are numbered and contain information as follows:
1 = General Information - includes torque settings and service tools
2 = Care & Safety - includes warnings and cautions pertinent to aspects of workshop procedures etc.
3 = Routine Maintenance - includes service schedules and recommended lubricants for the machine.
The remaining sections are alphabetically coded and deal with Dismantling, Overhaul etc. of specific components, for
example:
A = Attachments
B = Body & Framework ... etc.
The page numbering in each alphabetically coded section may not be 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.
All sections are listed on the front cover; tabbed divider cards align directly with individual sections on the front cover for
rapid reference.
Illustrations which show a dismantled component are numbered as a guide to the dismantling sequence, which generally
can be reversed for assembly.
Torque settings are given as a 'mean' figure which 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.
References to alternative servicing intervals are to be treated on a 'whichever occurs first' basis.
