Inspecting the Pump
The hydraulic pump is powered by the vehicle engine through a drive shaft and a PTO. The pump
should be visually inspected every working day.
Figure 5-5 Pump
When inspecting the pump:
1.
Start the engine and engage the hydraulic pump.
The pump should turn freely without excessive noise or vibrations.
2.
Check for oil leaks under the pump and at connection points.
3.
Lock out and tag out the vehicle (see
Locking Out and Tagging Out the Vehicle
If electrical problems occured with the pump, see
Pump Replacement
It is important to apply the following procedure after making a pump replacement or a pump drive
shaft replacement.
For standard drive shaft, do the following:
1.
Locate the hole with the yoke bolt (the yoke must be fully engaged on shaft).
Caution!
If the unit has to be driven away for repairs on the hydraulic system (e.g. following
detection of an oil leakage), turn the PTO switch to the “OFF” position.
