Hydraulic System

10.If specification is not met, remove piston pump back

plate assembly that contains the charge relief valve (see

Piston (Traction) Pump Service in the Service and Re-

pairs section of this chapter). Repair or replace relief

valve components as necessary.

11.A dynamic charge pressure test can be performed as

follows:

A. Position machine so that a load can be placed on

the traction system. For example, chain the machine

to an immovable object or chock all drive wheels to

prevent the machine from moving.

B. With pressure gauge still connected, sit in the op-

erator seat, start the engine and move throttle so en-

gine is running at high idle speed. Move functional

control lever to the transport position.

C. While monitoring the pressure gauge, push the

traction pedal in the appropriate direction (forward or

reverse) to allow traction system load.

D. The charge pressure should drop no more than

20% from no--load charge pressure measured in

step 8 above (e.g. if charge pressure in step 8 is 125

PSI (8.6 bar), charge pressure in forward or reverse

under load should be more than 100 PSI (6.9 bar)).

E. If charge pressure is good under no load, but

drops below specification when under traction load,

the piston (traction) pump and/or wheel motors

should be suspected of wear and inefficiency. When

the pump and/or traction motor(s) are worn or dam-

aged, the charge pump is not able to keep up with in-

ternal leakage in traction circuit components. Further

testing of the traction circuit should be completed

(see Piston (Traction) Pump Flow and Wheel Motor

Efficiency Tests in this section).

12.When charge pressure testing is complete, discon-

nect pressure gauge and tee fitting from the hydraulic

hose and hydraulic tube. Connect hose to tube.
