TEST OR INSPECTION
TRACK FAILS TO MOVE OR MOVES SLUGGISHLY- Continued.
Check if one brake releases by engaging track drive with control handle.
If one brake releases, replace/repair brake not releasing per paragraph 2.33. Go to step 4.
Hydraulic oil can be moderately flammable and can be an irritant to skin, eyes, and respiratory

Open center top right and center top left access doors per TM 5-3895-373-10. Install hydraulic
system tester at inlet (1) for pressure test per TM 9-4940-468-14. Check pressure at brake valve
inlet (1) with brake valve energized. Pressure at brake valve inlet should be greater than 135 psi
If brake valve inlet pressure is greater than 135 psi (931 kPa), replace/repair brake valve per
If brake valve inlet pressure is less than 135 psi (931 kPa), replace/repair left hand hydraulic
propulsion pump per paragraph 2.30.
