What to do when the check valve retainer will not unscrew from the lower Diaphragm cover assy. Tried penetrating oil first,Then soaked it Vinegar for a few days. No Dice. How important is the check valve rebuild? Jack Sims manual mentions drilling it out. Any thoughts? The Main valve has been rebuilt and it didn't have much rust at all (internally) Thanks in advance

Jack Sim (not Sims, Sim), who has restored over 300 Model 90 series ECOs says again, the only way is to drill it out. Be carful, the threads of the retainer are not at the top of the retainer, they are about 3/8" down. Start by drilling a small hole down the center of the retainer, keep enlarging your drill bit, as soon as you see the edges of the threads discontinue drillings, it is time to chisel out the remains of the retainer.

Keep in mind, after restoring over 300 of these units I should have come up with a better way, but consider this retainer has been in this unit for over 50 years, I have never found a better way.

I still have a few NOS retainers available.

I don't think he was calling you Sims,but rather referencing your manual afterwards.

All my life I have corrected the spelling of my last name. I had an uncle that got so tired of everyone putting an S on the end of our name he actually had his last name changed to Sims.
