WARNING
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
Before working on the hydraulic system ensure that the
engine is switched off and the starter key removed.
Operate the control levers to vent the hydraulic pressure.
Drain the hydraulic tank.
Disconnect the clevises from the tops of the valve spools 1.
Disconnect all hydraulic hoses from the valve ports (one
inlet A, four work ports B and one outlet C). Cover exposed
connections to prevent ingress of dirt. Mark the hoses to
ensure correct reconnection.
Remove the securing bolts 2 and lift the valve block 3 from
the machine.
Replacement
Replacement is a reversal of the removal procedure.
If a new valve block is being fitted it will be necessary to
transfer the adapters from the old valve block. Use new ‘O’
rings.
Ensure all hoses and ports are clean and free from dirt.
