3-50. A-1 CHARGING CUTOFF PILOT VALVE
This task covers:
Tool kit SC 4940-97-CL-E12
Whenever the A-1 charging cutoff pilot valve is removed and installed for any reason, a stationary vehicle
airbrake test (para 2-9) must be performed to check that the A-1 charging cutoff pilot valve functions
properly in the brake equipment arrangement. Failure to perform test may result in injury to personnel.
Make sure air is drained before removal of the A-1 charging cutoff pilot valve. Residual air may escape
and cause injury to personnel.
When removing or repairing brake valves or components, check air lines and pipes for corrosion, breaks,
splits, or loose connections. Repair of air lines and piping consists of replacing defective pipes, lines, and
connections. Refer to TM 55-2210-223-24P for identification of piping.
Remove two bolts (1).
Remove A-1 charging cutoff pilot valve (2) and gasket (3).
