When taking apart, fixing and putting together works
« on: January 07, 2020, 11:25:17 AM »
When taking apart, fixing and putting together a Crosman 2400 has a good outcome a feller can’t help but smile.

This 2400 had a stuck CO2 cartridge. I ended up drilling a hole in the end, screwing in a long dry wall screw and a pair of pliers to remove. Well the Orange CO2 seal came out with it and boy was it all scarred up.

I had no spare seal so I had a brain fart and recalled motorcycle oil seals can be rejuvenated by boiling a few minutes in water. So I boiled the Crosman orange CO2 seal and BAM that worked! The seal looked new.

Took apart the Crosman Custom Shop 2400 and installed the Orange seal, put the 2400 back together (first try) and it’s back to it’s happy self.

Huzzah!

I would say you probably overtightened the cartridge if the seal was messed up.... The most common cause of struck cartridges (other than paper labels) is firing the gun after the CO2 is completely empty.... That drives the piercing pin deep into the neck of the cart. and causes it to stick.... Unscrew the cap to remove the cartridge when there is still a tiny bit of pressure left.... That usually unsticks the cart....

That’s entirely possible Bob. The had set for at least six months without being shot. When I finally got the cartridge out I found corrosion on the end. Also the cartridge was extremely tight coming out of the tube. I cleaned out some very crusty caked up lube. That was original from Crosman. Anyway I appreciate the advice!

Automatic Transmission sealer will also soften/fix "O" rings.

Hi All,
          Just ran into a similar issue with a lever action rifle. My machine shop mentor had a C 02 powered rifle. We found a difference with Crossman vs Daisy C02 cartridges.   The Crossman have an external groove around the neck, right where the seal hits, Daisy did not.  And the Crossman's leaked like a sieve.  Tractor supply had a good supply of Daisy cartridges, thank Goodness.

Ah yah! I will admit that on looking at the jammed Crosman cartridge, the hole in the business end was large, and corroded.  Boiling the seal worked perfect though.

Hi Steve,
                These cartridges actually had a groove around the neck.  The groove let all the gas out as that was where his seals sealed.  The escaping gas deteriorated the seals.
