Introduction
This publication is designed for the benefit of JCB Distributor Service Engineers who are receiving, or have received
training by the JCB Technical Training Department.
It is assumed that such personnel have at least a sound knowledge of workshop practice, safety procedures and
general techniques assoc¡ated with the maintenance and repair of hydraulic earthmoving equipment. Details of such
are therefore generally omitted from this manual, the intention being to convey only the more specialised information
concerning particular aspects of the machine or component in question.
For example, renewal of oil seals, gaskets etc. and any component showing obvious wear or damage is expected as a
matter of course and information on these matters is therefore only included where a specialised procedure or range
of wear tolerances is required. Similarly, it is expected that components will be thoroughly cleaned and lubricated
where appropriate, also that any opened hose or pipe connections will be blanked to prevent entry of dirt and
excessive loss of hydraulic fluid.
For convenience the manual is compiled in sections, e.g. "Hydraulics", "Gearboxes" etc., but to find details of a
specific component, reference should be made to the alphabet¡cal index at the back of the book.
lllustrations showing a dismantled component are numbered as a guide to the dismantling sequence which can
generally be reversed for assembly.
Torque settings quoted are given as'mean'figures which may be varied by
i gø. 'Left Hand'and 'Right Hand'are
as viewed from the rear of the machine.
Replacement or additional pages for this manual will be issued from t¡me to time and should be inserted in place of
the existing pages which should be removed and destroyed.
Where possible, revised pages will bear an asterisk (*) against the new information, the page issue number in the
bottom right hand corner being similarly marked
