Fixed my Dashpot
Fixed my Dashpot...
My dashpot hasn’t worked for awhile now, so I pulled it and noticed oil was leaking from the ball bearing that seals the unit. So I carefully dugout the bearing and the rubber stopper under it. I submerged the unit in mineral spirits with the hole facing up and worked the plunger in and out until all the air was out. I then tapped the hole (where the ball bearing was ) with a 6-32 tap and installed a screw with a dab of epoxy. It’s been holding for two days now! Time will tell.
The only thing I would have done different is use a little thicker oil. It operates a little fast but it’s close, and it fixed the decel shutter and popping.

This worked for me, your mileage may very.

Very interesting! It's worth trying to fix since it's like $85 for a brand-new one. Never considered it a repairable unit! 
I'll have to see if I've got a bad one to monkey with.
