9. Disengage park brake (TM 5-3805-292-10).
10. Release door switch.
11. Run engine at high idle (TM 5-3805-292-10).
N OT E
Pressure must be a minimum of 360 psi (24.8 bar) at high idle.
Low idle pressure should be between 150 and 200 psi (10.3 and 13.8 bar).
12. Read pressure gauge and record anti-stall pressure reading at high idle.
13. Slow engine to low idle (TM 5-3805-292-10).
14. Read pressure gauge and record anti-stall pressure reading at low idle.
15. Shut down engine (TM 5-3805-292-10).
16. If pressure is correct, shut off engine, remove gauge, and connect lines. Proceed to step 20.
17. If pressure is not correct, loosen cap on hydraulic reservoir.
N OT E
Turning rod out willincrease pressure.
Turning rod in willdecrease pressure.
18. Remove cap on end of anti-stall control cartridge (Figure 7, Item 2). Loosen jam nut and turn threaded rod to
adjust.
19. If anti-stall control cartridge (Figure 7, Item 2) is damaged, replace tandem pump (WP 0068 for M400W or
WP 0078 for M400T).
