This kit is a good solution for people who want to revive their V1-V3 Crosman 760 without having to deal with dismantling the brass ring type pump head. 

Kit includes a rebuilt piston head assembly for Crosman 760 flat-head-type exhaust valve models. This will fit  all V1 & V2s & early V3s. The piston head includes OEM 760-042 piston head, rebuilt with a brand new pump-cup and new wiper felt. Buyers will also receive printed instructions on how to properly adjust the replacement piston head on the piston assembly.


This kit also includes the seals and breech gasket for your exhaust valve.  The kit also included printed instructions on how to replace the quad-ring seal inside the valve cap. The quad-ring is the trickiest part of a quality reseal.

This kit  fixes most issues with a self-cocking model failing to pump-up, build pressure and fire.
