Crosman 140 pump rod adjustment

I have a Crosman 140 which was fully rebuilt a few months back and I'm concerned about the adjustment on the pump rod.I notice when I pump it quick it does not auto **** but on slow pumps I can hear the air **** in with each stroke.When it was rebuilt the nut at the barrel end of the pump rod was left loose "should it be loose or locked down tight?" and as a reference point how much of the felt should be seen in order for the pump cup to pull in the right amount of air? The gun holds pressure and is strong but as I stated I have to pump it slow.I can only see about 1/8" of the felt at the end of a opem pump stroke.

I own a Crosman 140 (c. 1962). The nut should be tight.

My gun is original since I got it back in the 60's and about a 1/4 to 3/8 of an inch of the felt is visible. It has never been adjusted and works fine. Keep it well lubricated with 3 in 1 oil or gun oil.

I just rebuilt my Sidekick engine, four cylinder 8 valve Sidekick. I had NAPA rebuild my head. After putting it all together I adjust the 1,2,5, and 7 valves at TDC, but when I rotate to do 3,4,6 and 8,...


Did you pump up the lifters with oil? They are what oils the valves. As the motor runs they act as pumps and hydrolic shock absorbers at the same time. They pump oil up through the push rods. So when you try to adjust them they collapse and don't fill back up.

A drill press and push rod is the best way, tighten the pushrod into the chuck. Leave it off. then place the lifter in a small bowl of oil and press it down with the lever on drill. do it over and over until it gets hard to pump.

Crosman 766 wont hold air areadly oiled the seal


Try raising the pump lever and douse the inside with Barricade or Remington spray oil, then slowly pump it halfway or until you hear the air loss, do this several times or "rinse and repeat" until it keeps it's seal. Another good idea is to do this every couple months, leak or not!
