TRUCK SERVICE MANUAL
Check oil level. An overfilled pump reservoir can be a cause
for leakage. The oil in the steering system expands as heated
during normal usage. If overfilled the excess is forced through
the reservoir cap vent. Operate the engine and steering
system until normal operating temperature is obtained.
Remove the reservoir cap and check level. Adjust the oil level
If leakage persists with the oil level correct and the cap tight,
replace the cap.
Air in the system can also cause fluid level to rise, especially
after system repair. Bleed the system as described in the
MAINTENANCE section of this chapter.
Tighten hose fitting nut to specified torque. If leakage persists,
replace discharge fitting and reface hose tube flare or replace
hose as required.
If either the return hose or the pressure hose leaks, other than
at the nut connections, replace the hose.
Tighten fitting to specified torque. If leakage persists, replace
both "O" ring seals.
Replace reservoir "O" ring seal.
Replace drive shaft seal after inspecting and thoroughly
cleaning the sealing surface. Replace drive shaft if severe
pitting is found. If the corrosion in the lip seal contact zone is
slight, clean the surface of the shaft with crocus cloth. Always
replace the seal if the shaft is replaced.
