Hydraulic Pressure
Hydraulic fluid at system pressure can injure you.
Before disconnecting or connecting hydraulic hoses
or couplings, vent the pressure trapped in the hoses in
accordance with the instructions given in this
publication.
HYD-1-5
At the kingpost, disconnect and plug the hydraulic hoses A
and B, marking the hoses to ensure correct reconnection.
Support the backhoe by placing a sling from a crane
around the boom ram to kingpost pivot. (If the boom and
dipper have been removed, place the sling around the
kingpost.)
Unscrew and remove the four kingpost hydraclamp nuts C.
Using the crane, ease the kingpost clear of the hydraclamp
bolts and lift the excavator assembly away from the
machine.
Replacement
Replacement is a reversal of the removal procedure.
Apply JCB Special MPL grease to all pivot pins.
Tighten the hydraclamp nuts C to nip the units then back
off half to one turn.
When assembly is complete, operate excavator services
fully to bleed the hydraulic system then check the hydraulic
level.
