SOURCE: Hello, i have a Crosman 760 Pumpmaster Air Rifle,

Sounds like it has a bad o-ring. you can take it apart and replace the o ring for under a dollar. just make sure you look at how it goes back together when you take it apart they are very simple. just make sure the carefully take the right side cover off with the left side of the rifle laying on a table, everything should stay assembled this way so you can look at it. the part you are looking for is in the large chamber that the pump goes into. from the back (the side opposite the pump) remove the spring and the metal piece behind it, then use something the shove the big brass part out of the chamber and the o ring is on the big brass part . take the old o ring to a hardware store to get another one.

My crosman 1377 won't pump up. Is there a replacement part available for this problem?


The pumps seal is bad so take it apart and cut a piece of leather out to fit
Coat the leather with Vaseline and it will operate just fine for you
