In this video, I show you how I fix my 18(Purchased 1993) year old pumpmaster 760. A lot of people have these old guns laying around, and they most likely do not pump very well, if at all. Most likely, the rubber o-ring and one rubber pump cup are old and need replacing.

The part numbers for the 760 Pump Master are: O-Ring(130-035) and Pump Cup(760-140).

If you have the 761XL(1972-1981), they look like: O-Ring(760-009) and Pump Cup(760-042), but double check the parts diagram located here: https://www.crosman.com/pdf/manuals/crosman/761XL/C761XL-EVP.pdf

In my case, I modified the existing materials to work again, but I would suggest that most people just replace existing with new. The gun itself is only worth $30, so I figured why spend $15 on parts?
The gun works like new, except the pump is a little loose and doesn’t hold itself in, other than that, it shoots with as much muzzle velocity as day 1.

Hope this video helps many out there revive life into their old 760′s!

Cheers.

David.
