Crosman Trapmaster 1100 Disassembly, Part 5

A little longer…
03241238
Just two pieces left…
03241239
Rear cartridge piercing.
03241240
I braced it in a vice and unscrewed it.

03241241
Well two pieces came out…
03241242
The o-ring has an old nick.
03241243
The piercer won’t come out…soaked it in some WD40.
03241244
So the valve tube assembly end won’t come out because one screw is sheared off. I drilled it down below the surface.
03241245
Finally. Man, look at that rust. I was hesitant to take the Trapmaster apart as it looked ok, but clearly it needed this.
03241246
Even the o-ring is rusty.
03241247
Valve spring.
03241248
Valve assembly.
03241249
At least the valve seat looks good.
03241250
Valve parts.
03241251
That seal looks ok.
03241252
Finally was able to jimmy out the piercing pin with a broken dental pick.
03241253
The screen retainer was so rusty it broke when I removed it.
03241254
Dang, that’s nasty.
One more post…

Woah! I just picked up a 1100 and was fearing what I would find inside. Thank you for posting your tear-down. Maybe I'll be able to get it back together with your great pictures and detail of the disassembly.

I too am restoring an 1100 Trapmaster. The firing valve and chamber are leaking, much less corrosion. Firing valves are hard to find, looks like I will have to make one from Viton rubber.

Also, shells are hard, Phoxx manufacturing out of the Dakotas used to make these until recently. So I made some from 7/16" brass tube and washers, soldering the washer to a short length. The seals held enough pressure for 4 shots. I made wads from cardboard and a punch, using a bit of oiled tissue as a column to better seal.

If you know of sources of firing valve and shells, please include a link. Otherwise, I will have to make both.

For rebuild kits I'd try Bryan and Associates as well as the other guys on my short list of suppliers:
Bryan and Associates, Mac1, Precision Pellet or JG airguns.

I'm lucky in that I came across a few boxes of shells at a yard sale a while back, they do come up on Ebay, Gunbroker and Auctionarms from time to time and that's probably where I'd start looking.
