Service Manual 406 407 408 409

Introduction
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 a sound knowledge of good workshop practice, safety procedures and general
techniques associated with the maintenance and repair of hydraulic earthmoving equipment. Details of such may therefore be
omitted from this manual, the primary intention being to convey the more specialised information concerning particular
aspects of the machine or component in question.
Renewal of oil seals, gaskets, etc. and any component showing obvious wear or damage is expected. It is also 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", "Electrics" etc., but to find details of a specific
component or its application, reference should be made to the alphabetical index at the back of the manual.
Except where a maximum and minimum figure is given, torque settings quoted in the text are intended as 'mean' figures which
may be varied by + or - 3%. Where no figure is quoted in the text, refer to page 1/1 - 3.
