1.
AUGER/CONVEYOR DOES NOT OPERATE OR OPERATES SLUGGISHLY- Continued.
WARNING
Hydraulic oil can be moderately flammable and can be an irritant to skin, eyes, and
respiratory system. Avoid prolonged exposure. Eye protection and rubber gloves
must be worn when working with hydraulic oil.
NOTE
The left hand auxiliary hydraulic pump supplies the left hand auger/conveyor circuit
and the right auger/conveyor flow divider. The output of the flow divider supplements
flow to both auger/conveyor motors.
Step 8.
Install hydraulic system tester at port (8) for flow test per TM 9-4940-468-14. Check flow rate of left
hand auxiliary pump discharge port (8) to right auger/conveyor flow divider.
If discharge is at least 5 gpm (19 l/min) at 2500 psi (17 238 kPa), replace right auger/conveyor
flow divider per paragraph 2.55 and repair per paragraph 2.49.
If discharge is less than 5 gpm (19 l/min) at 2500 psi (17 238 kPa), replace/repair left auxiliary
hydraulic pump per paragraph 2.42.
Step 9.
Disconnect hydraulic system tester per TM 9-4940-468-14. Reconnect all hydraulic lines. Install
right access cover per TM 5-3895-373-10. Close right access door per TM 5-3895-373-10. Close
center top left and center top right access doors per TM 5-3895-373-10. Close rear top left access
door per TM 5-3895-373-10. Close rear top right access door per TM 5-3895-373-10.
