IMPLEMENT PUMP DISCHARGE TESTS CONTINUED
Margin Pressure Test and Adjustment
14. Remove 8T0856 pressure gauge (Figure 4, Item 1) from 1U5793 pressure differential gauge fitting (Figure 4,
Item 2).
15. Install 8T0861 pressure gauge (Figure 4, Item 1) on 1U5793 pressure differential gauge fitting (Figure 4,
Item 2).
16. Ensure parking brake is engaged and implement lockout switch is in UNLOCK position (TM 5-2410-241-10).
17. Start machine and allow it to run for 15 minutes to reach normal operating temperature (TM 5-2410-241-10).
18. Ensure that blade is at rest, flat on the ground (TM 5-2410-241-10).
19. Set machine to HIGH IDLE (RABBIT MODE) on the throttle switch (TM 5-2410-241-10).
20. Move bulldozer blade control handle half way into the RAISE position and record pressure shown on the
differential pressure gauge (Figure 4, Item 3).
21. Differential pressure gauge (Figure 4, Item 3) should read 290 to 320 psi (2,000 to 2,200 kPa) while blade is in
motion.
a. If pressure is NOT within specification, proceed to step 22.
b. If pressure is within specification, proceed to step 36.
