Check your readings against that stated below. If your
readings differ, relief replacement and or component
repair may be required.
Pressures should read:
•
5100 PSI (35160kPa) the relief is reached in
attempted forward or reverse motion.
Drive pressure troubleshooting:
8.
If one reading is low, swap the relief valve with a
similar one and recheck. If the reading improves,
replace the faulty relief valve.
9.
If two readings are low, but on different circuits
(pumps), perform step 8 for both.
10.
If both readings are low on one pump, disconnect
the drive hoses from the suspected ports and plug
them at the pump. Cap the hoses to prevent con-
tamination and then recheck the pressures at
those ports. If the reading improves, the drive
motor is at fault. If the reading does not improve,
one pump (in the tandem assembly) is at fault.
11.
If all 4 readings are low, it is unlikely that all four
relief valves are faulty. The tandem pumps are
most likely not working properly.
