(7)
Remove engine access panel
NOTE
If pressure is set at 3,000 psi (20 684 kPa), go
to Step (12). If pressure will not adjust to
3,000 psi (20 684 kPa), go to Step (8).
(8)
With the aid of an assistant, use hydraulic
valve manual override lever to stall out 4-in-1
bucket hydraulic circuit on FEL valve
block (6).
(9)
Observe gauge (4). Gauge should read
3,000 psi (20 684 kPa).
NOTE
FEL relief valve only requires small
amount of rotation to properly adjust
hydraulic pressure.
Turning FEL relief valve clockwise
increases hydraulic pressure and turning
counterclockwise lowers the pressure.
(10) With the aid of an assistant, use 6-mm Allen
wrench to rotate FEL relief valve (7) until the
correct pressure is displayed on gauge (4).
NOTE
If pressure is set at 3,000 psi (20 684 kPa), go
to Step (12). If pressure will still not adjust to
3,000 psi (20 684 kPa), go to Step (11).
(11) Perform hydraulic flow test (Para 10-7).
(12) Shut OFF engine (TM 5-2420-230-10).
(13) Remove gauge (4) from test port (2) on backhoe valve block (3).
(14) Install cap (1) on test port (2).
b. Follow-On Maintenance.
(1)
If removed, install engine access panel (TM 5-2420-230-10).
(2)
Install spare tire and carrier assembly (TM 5-2420-230-10).
