Crosman 1st time reseal of Crosman 2250 help needed

I have been out of the hobby for a few years and thinking about getting back in. I have 4 Mountain Air Crossman 2250 variants that I bought from him some time ago. Some have stuck CO2 carts and all need a reseal. I am a car mechanic/nut of about 40 years and have done several TX200 kits but never cracked open a 2250. I see quite a few options on e bay for a seal kits with what looks like 5 washers and a spring as well as a valve stem for around $25 shipped.

I assume that is the one to get if you want to reseal the who pistol - am I right?

Also is there a place I can go to get printed overview (or one I can print) of the strip down and reseal process online? I know there are a million videos but I like a manual if you will to reference as I go along.

Thanks!

GOD BLESS

You'll find the manual and EVP for those pistols here - https://support.crosman.com/hc/en-us/articles/203543480-2250B-Owner-s-Manual-EVP-1998-Present

It's very similar to the SSP250 that I have and it's really easy to work on.

As a mechanic, I can say that working on a co2 gun is a lot like tearing down and rebuilding a brake master cylinder. Simple, once you see what everything does. A dab of grease on the o-rings always make things go together a little more easily. I'm sure that there are youtube vids on it.

I would not go to ebay for parts. Mike Baker, TMac's or Pyramid will likely have what you need without the ebay risk.

Cheers,

Fantastic - TY for the link. as well as the nod to get parts/seal kits from vendor vs e bay. I will look again at Baker airguns and PA. I had looked at both of them before posting and did not see seal kits for the 2250/2240 guns. Might have to call them to ask.

Also appreciated the mention of master cylinder. If I can disassemble and see how it goes together I can get er' back together with fresh parts. Love my collection of Haynes, Chiltons and OEM service manuals I have gathered over the years but nothing beats bench time with disassembly and clean up then reassembly.

I have 4 to do so will start with 1 and build from there . Probably going to sell off the boutique guns and keep these little Crosmans since I have had them so long and they got me started over 20 years ago into adult airguns

Thanks again for the help my friend.

~GOD BLESS~

You got this. Such simple rigs to work on. Now if you need a valve stem yo will be ordering that (and mountain air makes his own but "thinking" no problem with any correct vavle stem you need. They do not commonly need replacing but does happen (will leak down barrel).
Otherwise the sizes are listed in the crosman pdf and while making sure you get the correct material for Co2 Ace hardware (and our ma & paw auto store) carry the rings cheap.
Fix them up and give use an update, remembering the oictures.

No worries, John. I tried to pick something relatable. I like the manuals too, but wish we'd had youtube back in the day... It's been a solid mechanical resource.

JG Airguns is another good option (although not everyone gets along with Heather, apparently).

Best of luck,

Jeff

Jeff - I agree about youtube and help when needed. Changed the game for sure. If I get stuck on a project that is my next stop if the manuals don't get me there.... I'll check out JG Airguns as well. Appreciate the additional source for parts as well.

~GOD BLESS~

John,

I was thinking about ACE or other local stores for o rings - I'll hit gthe seal kits this time around and then see what all is needed going forward. Wil get some pics for sure. I have one in 177, 20 , 22 and 25. The 20 and 225 are LW barrels with crosman steel on the 177 and 22. I get sentimental about things easy and while I have other rifles I have had those little Mountain Air guns for a long, long time. So they deserve to be brought back out and rehabbed.

~GOD BLESS~

I'm with you, John.

Some of the things I love about airguns are...

They're easy to diagnose. No electronics needed. Has seals and leaks. Okay...
You don't need a lift or to pull the wheels off.
You can fix them while seated or standing (instead of laying flat on your back on a creeper).
The're not loaded with sensors that usually give you bad data because of wear in the wiring.
They don't have wiring (and if they do then I ain't buying one).
You don't have to subscribe to a service just to figure out what's wrong.
They don't have to be and stay EPA compliant (yet).
You don't have to mortgage your soul to Mac or Snap-On for the tools to repair them.
I'm my only disgruntled customer.

Good luck,

J~

Jeff,

All your points are well stated no doubt. Your comments speaks volumes about the journey you go on when wrenching for so long. I grew up with the 3 rules of spark, air or fuel as the main culprits. While I love what electronics have done to improve our on the road experience they sure have added layer upon layer of techno babble just to get er' done now a days.

I can see from both using and from the exploded diagrams that the crosman 2250 platform is simple and straight forward. I have tuned many a TX200 and HW97 and also built the obligatory RWS 850 bottle gun conversion. Even made my own simple reg tester for that project. Then I drifted into the dark side if you will of pcps and while it was a fun ride I yern for the simpler days of the magic feeling I got from my first ever Mountain Air custom guns.

I haven't shot for over 2 years so I am refreshed and renewed if you will. Very excited to get back into the hobby. It could be due to a recent trade I made of a pencil, a single die and a AR for a 86 F250 with a transplanted 7.3 International IDI. Pure mechanical diesel with none of the tech you get with a truck today. I can see it now me loading up the freshly resealed MA 1750, MA 2050, MA 2250 and the MA 2550 in Iddy and driving to the lake for some afternoon co2 plinking . Brings a smile to my face for the simplicity of it all..... Stay tuned.

~GOD BLESS~
