Joystick from machine number 807147
Dismantling
The illustration shows a typical joystick. Slight variations may
occur depending on the application.
The numerical sequence is intended as a guide to
dismantling, assembly is the reverse of this sequence.
Note: Ensure that the components of the valve units are kept
together as sets and returned to their original locations in the
body. Do not mix components from different valve units and
do not mix components between different joysticks.
Assembly
Lubricate all parts with hydraulic fluid before assembly. 'O'
rings and seals should be lightly coated with petroleum jelly
prior to assembly. Ensure that valve units are returned to
their original bores in the valve body.
Select shims 7 so that there is a small clearance between
cam plate 6 and the tops of plungers 11 when the lever is in
the neutral position.
Coat threads of item 5 with JCB Threadlocker and Sealer
(High Strength) before assembly.
