Service Manual WLS 422ZX

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.
For convenience this manual is compiled in sections, e.g. "Hydraulics", "Electrics", etc. but, to find details of a specific
component, reference should be made to the alphabetical index at the back of the book.
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. Where no figure is quoted in the text, refer to page 1/1 - 3.
'Left Hand' and 'Right Hand' are as viewed from the rear of the machine looking forward.
