From a Ingersoll Rand service manual — check it applies to your exact model before use.
Procedure
- Coat the Reverse Valve Seal (2A) with O-ring lubricant and install it in the groove between the head and lock pin hole.
- Insert the Reverse Valve Spring (3) into the plain end of the Reverse Valve.
- Insert the Valve Lock Pin (4) into the small hole in the side of the Reverse Valve.
- Start the Reverse Valve into the bushing, aligning the Valve Lock Pin with the timing notch on the bushing.
- Holding the lock pin hole downward, push the Reverse Valve into the bushing against the Reverse Valve Spring compression.
- Use a small diameter rod to force the Valve Lock Pin into the slot in the wall of the bushing.
- After the Valve Lock Pin has engaged the slot, slowly release the Reverse Valve and it will stay in position.
