Title: Fixed Crosman 2100's - yay!
Post by: Turbinator on May 06, 2022, 02:43:52 PM
Hi folks, there may be millions of threads on Crosman 2100's, just wanted to throw in my experience getting 2 of these up and running.

Have one from 1990 vintage, and another from 1992.  Neither were building up pressure.

Bought 2 replacement piston cups, installed, and now both pressurize and seem fine in dry fire testing.

That roll pin can be a bit of a pain, but having roll pin punches and careful hammering got them out just fine.

Seems I didn't need to touch the seals, or the valves / valve stems.  Oiled both with Pellgun oil on the piston cup and away we go...

That's all! :)

Killed hundreds of rats with my 2100 in Asia.

It was a good gun   ;D

Wow, hundreds?  Still got yours?

Was over-penetration a problem, or were you in an environment where it didn't matter?  What was your preferred ammo?

Yes, a little over 600 rats  ;D

A Polish friend of mine bought it from me after its years of good service.

Being a bit of a machinist, he tweaked the trigger, modified the probe, and installed a suppressor.

It particularly liked the Philippine made Eaglehead  and Hammerhead pellets, and no, we have no power restrictions over there.

I still have photos of it with a Surefire Z2 flashlight mounted to its scope, but I could not seem to access PHOTOBUCKET anymore  :(

True, I was able to retrieve some of them.

Wow, over 600... that's a lotta notches on that stock ;). The primary enemy of my airguns over the years has been snails.

Power restrictions - wow - I never thought about that.  I guess some countries may have restrictions.  But I heard that Philippines are pretty good about personal gun ownership in general anyway, so not surprising that you didn't have any restrictions there on power output.

Never had any trouble removing pump pivot roll pins.
Now, installation....THAT is another story!
I set myself up a Grizzly 1 ton bench arbor press with a fixture to hold the pump tube/rifle in the proper
position to press the roll pin back in... I had to machine the tooling.
It is still a work in progress, but getting better.
I do a bunch of them.............

A press fixture sounds like the cat's meow to get these roll pins done...  I've had a bit of roll pin experience prior, but I haven't done a bunch of 2100's.  I did find that squeezing roll pins with some pliers to tighten them up a little bit, does help with reinstallation.  They're pretty tough to squeeze though.  I was able to hammer in my roll pins for the 2100 with no real issues.  Removal also was pretty straightforward, having roll pin punches really helps with that.  If I find myself having to remove the pins often, I'm going to want either a fixture such as what you have, or another pin solution that isn't so inconvenient to remove each time I need to get in there.  Sounds like you're pretty much a roll pin pro!

I use a C clamp as a press to re-install stubborn roll pins.

I wanted to build a pin press ala a chain tool. That would take care of alignment of the ALL the parts and just screw in/out,
but the benchtop press was an easier solution.  I prefer elegant, but in this case, simple won out...
