SHEET 3 OF 3
With engine operating at full throttle, ensure that LIFT ARM and BUCKET
control levers (4 and 5) are in NEUT. position. Ensure that CLAM control
lever (6) is in HOLD position. Read pressure gage indication. Pressure
gage shall indicate less than 500 psi. If pressure gage indication is
less than 500 psi, go to step (6) below. If pressure gage indication is
more than 500 psi:
Move each control lever (4, 5, and 6) a small distance in both direc-
tions while watching pressure gage. If pressure gage reading does not
decrease, go to step (b) below. If pressure gage reading decreases, con-
trol levers and linkages are not adjusted correctly or the spool center-
ing spring is damaged. Check control levers and linkages adjustment
(page 3-720). If adjustment is okay, replace control valve assembly
Replace hydraulic filter (refer to TM 5-3805-262-20) and recheck neutral
pressure. If pressure is still high , remove hydraulic return lines and
check for dirt or other restrictions.
Turn off engine and operate hydraulic control levers several times to re-
lieve hydraulic pressure.
Disconnect pressure gage from quick disconnect coupling (1) and reinstall
cap on quick disconnect coupling.
