Crosman 760

[bpb1brou]

I have recently dug up out of the closet my old Crosman 760 manufactured in 1979.    It holds absolutely no air, 1 pump and you can hear it escaping from the muzzle as well as the breech.    What is your opinion on getting it back to operating condition?    I know some will say to just trash it, a new one can be purchased for $35.     But, I suppose this just has some old memories.     So, how difficult would it be to tackle it by myself?     I have dissassemble the receiver and put it back together a number of times.    What parts would I need to order?  
I have a Benjamin 392 that I use frequently, so the 760 wouldn't be my go to gun.    Any help/suggestions would be appreciated.
Thanks,
Bert

Does it need to be cocked prior to pumping?
Maybe the seasl are dry and a little pellgun oil (or reasonable facsimile) worked into the valve will fix it.

Yes, it does require cocking.      I did try pellgunoil, but it made no difference.    Any thoughts on what it would take to bring it back to life?

Probably needs new seals. Check on the Crosman forum. There are several folks there that know where you can get parts for the older guns.
My first thought was to get a new 760 and swap out the guts, but the old guts and the new guts may be unswappable if yours needs to be cocked before it can be pumped.

This may/maynot make a difference.   But, it can be cocked before pumping and vise-versa.     It is the metal receiver, not plastic and also has a bolt action as opposed to the new models that have the action that you just pull back.    Thanks for your input.      I'll give it a try posting on Crosman.

it might be the "pump cup", a small, round, cup shaped rubber peice that frequently goes to pot after lengthy use. they are cheap parts to replace.
