What’s wrong with crosman model 130?

[yoopper]

I have an old 130 that I re-sealed , but it doesn’t build up enough pressure. I think all the seals (o-rings and pump cup) are in good condition. This model has wood grips and pump handle. Is model supposed to have a spring on the “hammer “ rod? Does anyone have a diagram of the complete assembly?

Any help is appreciated.

Crosman has a lot of info on their site.

Thanks biohazardman for the information, but my pistol is manual cocking. It has a button on the left hand side that you slide forward before pumping up the pistol. The valve is slightly different in that it does not have a blowoff cap but a inch long pin that sticks out of the the rear and rests against the “hammer “. So far, none of the diagrams I’ve seen show this configuration. Any comments?

Thanks,

I always enjoy the pictures ( just do not like watching endless video's) here:

Unless you replaced every seal, it's probably still leaking (inaudibly). I had one of those decades ago, and though it didn't leak it had too little power to interest me.

Nope sorry no memory of that one at this time.

Mystery solved!


Thanks to all who helped solve this problem. Turns out the pop-off pin located in the air valve was too long by 0.080” and did not allow the full volume of air to dump at firing. This problem is my fault for having a mess on my work bench and getting parts mixed up. But it works great now.
