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.
Step 6.
With paving machine off, check auxiliary hydraulic system suction lines using hand pump. Check
suction lines at right hand auxiliary hydraulic pump (4) and at left hand auxiliary hydraulic pump (5).
Replace or repair components (auxiliary hydraulic system suction hoses, lines, and fittings per
paragraph 2.54, hydraulic reservoir components per paragraph 2.53) as necessary.
Step 7.
Install hydraulic system tester at ports (6 and 7) for flow tests per TM 9-4940-468-14. Check flow
rate at auxiliary hydraulic pump discharge. Check discharge at right hand auxiliary hydraulic pump
port (6) and at left hand auxiliary hydraulic pump port (7). Flow rate should be at least 5.5 gpm (21
l/min) at 2750 psi (18 961 kPa).
If discharge is less than 5.5 gpm (21 I/min) at 2750 psi (18 961 kPa), replace/repair auxiliary
hydraulic pump per paragraph 2.42.
