Replacing the hydraulic pump
Replace the hydraulic pump if:
•
system oil pressure is abnormally low
•
pump operation is unstable
•
pump is excessively noisy
Expect oil spillage with this service. When factory floor
drains must be oil-free, install a barrier to block oil.
Limit oil spillage by using drip pans, plugging each line
and port, and allowing a generous drip time.
CAUTION
If replacing the hydraulic pump because a catastrophic
hydraulic pump failure contaminated the hydraulic oil
system, see
Cleaning a contaminated oil system.
Service steps
