3.1 CHECKING CAB-TILTING PUMP
Checking cab-tilting pump
1.
Check all hoses and connections for any
leakage.
2.
Disconnect the hoses from the pump and
close off the connections to the pump.
3.
Check the oil level in the pump.
4.
Place the switch cock in the “lowering”
position, apply a few pump strokes and
check whether the pressure-relief valve is
activated. Then place the switch cock in the
“lifting” position and check the operation of
the pressure-relief valve again.
5.
Inspect the pump plunger for any leakage.
If the above checks of the pump are
unsuccessful, the lifting cylinder is defective. A
defective pump is often the result of
contaminated hydraulic oil.
