CORRECTIVE ACTION
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 following test requires use of a hydraulic system tester. Install tester in-line at
flow test point indicated by each individual test per TM 9-4940-468-14. Make sure all
ratings of fittings and hoses used are adequate for maximum pressures and flows
being tested. Pressure requirements of step 2 must be met to verify flow rate.
Step 3.
Open center top right and center top left access doors per TM 5-3895-373-10. Open rear top right
access door per TM 5-3895-373-10. Open rear top left access door per TM 5-3895-373-10. Install
hydraulic system tester at inlet (1) for flow test per TM 9-4940-468-14. Check maximum flow rate
supplied to auger/conveyor motor inlet (1). Flow rate should be at least 7.9 gpm (30 l/min).
If flow rate is at least 7.9 gpm (30 l/min), replace/repair auger/conveyor motor per paragraph
2.69.
Step 4.
Install hydraulic system tester at outlet (2) for flow test per TM 9-4940-468-14. Check maximum
flow rate between manual auger/conveyor speed control valve and auger/conveyor control valve at
control valve inlet (2). Flow rate should be at least 7.9 gpm (30 l/min).
If flow rate is at least 7.9 gpm (30 l/min), replace auger/conveyor control valve per paragraph
2.55 and repair per paragraph 2.45.
