Life saver of a post. Rebuilding a micro rock on a customers halfy. The piston oring was more gel than rubber.

Edited to add good info to the MCB brain trust. Found a great Typhoon diagram on the BookFace Palmers group, and Firpo got back to me with corroborating info. Installed the correct O-rings and re-assembled with no leaks! It should be noted that the Reg seat that goes on the tiny brass piece with a spring is not called out. It's a specialty Palmers seal. Mine was missing. It is the same seal used in stabilizers. DocFire includes them in his stabilizer rebuild kit. Craig may still have more through Palmers.
