Title: 397PA Pump Cup
Post by: CENTURION on March 25, 2020, 07:27:42 PM

The pump cup on my 2013 397 PA finally went, funny thing is it looked in mint shape when I pulled it out. Popped a new one in, and it has its usual arm breaking pump hardness and velocity. Hopefully the new one goes a little longer, I've had Crosman 140's 50 years old the cups were still functioning. ;D

Soak the old cup in ATF. It'll swell, soften it. I've brought a couple back, that way.
