TRANSMISSION STALL TEST CONTINUED
6. Return steering and transmission control from FORWARD position to HOLD position, then to REVERSE posi-
tion.
7. Monitor and record pressure readings from left hydrostatic pump and right hydrostatic pump.
a. Left hydrostatic pump pressure should be 6,563 290 psi (45,250 2,000 kPa).
b. Right hydrostatic pump pressure should be 6,476 290 psi (44,650 2,000 kPa).
8. Return steering and transmission control to HOLD position, stop engine, and relieve hydraulic system pressure
(WP 0162).
a. If pressure is not within specifications, recalibrate electronic pressure override valve. Refer to
Transmission Drive Pump Override Calibration in this work package.
b. If pressure is not correct in both directions of travel, the electronic pressure override valve needs to be
calibrated. Refer to Crossover Relief Valve Adjust in this work package.
WARN I N G
DO NOT disconnect or remove any hydraulic system hoses, tubes, or fittings unless
engine is shut down and hydraulic system pressure has been relieved. Escaping hydraulic
fluid under pressure can penetrate skin.
At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before removing
any hydraulic fitting.
Wear protective eye covering and gloves.
Lubricating/hydraulic oils used in perfomance of maintenance can be very slippery.
r
Immediately wipe up any spills.
Failure to follow these warnings may result in injury or death to personnel.
9. Stop engine, relieve hydraulic system pressure (WP 0162), remove pressure gauges, and install cab floor plate
(WP 0205) when tests and adjustments are complete.
10. Perform transmission stall test after calibration.
