I have Crosman 760 older model which I got recently as a result of Lauchin's give away game.

The gun was OK at first, but after couple of shots I noticed it under 300 fps and don't hold air as it should,
so I wanted to repair it. First I put some pellgun oil on the pump seal and leak stopped,
I shot about 30 good shots with about 420 fps on 10 pumps and left it overnight. Next day as I pumped it, it started to leak
after about 5 pumps, you can hear psssssst from the barrel. I put more pellgun oil but no use this time, after 3-4 pumps air escapes.

And here is a problem - I can't disassemble it because I don't know how to remove pump arm pin, this one

This is not a "c" clip, any ideas how to remove it?

The 760 is pretty easy to work on, the clip can be removed with a very small screw driver like the ones you would use to tighten screws on glasses or if you have a very fine pick, just pry the clip off but make sure it dosent go flying off. Sounds like your valve isn't sealing properly if your saying you hear air out the barrel.

Thank you for reply, Ace.
I have a bunch of small screwdrivers, but can't remove this clip. It is too small to pry off also.
Any other tool can be used?

I understand what you mean but trust me it can be removed this way that's how I remove mine, slowly pry it around the pin. You might have to use to small screwdrivers to keep the clip from spinning around.

That sure is a fiddly looking clip. I wonder if a normal c clip would fit to make it easier next time.
