Removal

1. Remove the four mounting screws (key 36, shown in figure 14) and remove the relay from the transducer. Be

careful not to lose the bias spring (key 34) and input diaphragm (key 38).

relay body assembly.

3. Remove the exhaust port assembly (key 33) from the relay assembly.

4. Inspect the springs, exhaust seat, valve plug, and other parts for wear or damage; replace as necessary. Note: the

valve plug supply seat is an insert in the relay body (key 41). If this insert is bad, replace the relay body.
