3-56. RUBBER SEATED CHECK VALVE
This task covers:
Tool kit SC 4940-97-CL-E12
Whenever the rubber seated check valve is removed and installed for any reason, a stationary vehicle airbrake
test (para 2-9) must be performed to check that the rubber seated check 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 rubber seated check valve. Residual air may escape and cause
injury to personnel.
This is a one-way valve. Note direction of air flow.
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.
Disconnect two air connections (1) and (2).
Remove rubber seated check valve (3).
