If you have a Crosman 760 Pumpmaster that doesn’t hold pressure or leaks while pumping then you could just rebuild it instead of replacing it. It’s quite a bit cheaper ($10) than a new air rifle.
The Crosman 760 Pumpmaster Reseal/Rebuild kit includes the following items:
- check valve(#1322-056)
- valve stem assembly(#1322A011)
- pump head cup(#760-140)
- Inner and outer valve body o-rings(#130-034, #130-035)
- exhaust port seal(#130-036)
**** This kit will not work with pre 75 Crosman 760 air rifles.
