Priming Hydraulic Pumps

Hydraulic System: Service and Repairs
Whenever the hydraulic system is flushed, the hydraulic system is charged or
hydraulic components are removed, it is important to properly prime the hydraulic
pumps. Hydraulic pump priming ensures that the gear pump and piston (traction)
pump have adequate fluid during initial start−up and running. The pumps can be
primed by using a remote starter switch (see
engine which allows the pumps to prime.
Use the following procedure to prime the hydraulic pumps:
1. Make sure that key switch is in the OFF position and key is removed from
switch.
2. Check hydraulic reservoir fluid level and adjust if necessary.
Note: It may not be necessary to remove the wire from the starter solenoid
B+ terminal when connecting a remote starter switch.
