Crosman Trapmaster 1100 Disassembly, Part 4

Really, I’m not done…

Remove the ejector spring.

Springy…

Shell extractor. Did I mention this thing uses shotshells?

Remove the sear.

This will get a bit of polishing.

Now the valve assembly comes out. Still attached to the tube/
Remove some screws to get the hammer assembly off.

One piece lighter.

The spring won’t come off without prying and there’s no harm in leaving it.

Valve.

The pin is swaged in.
Remove the c-clip and the “barrel stop”(?) comes off.
Interesting.

Valve release stem comes out.

It looks better from a distance. Seems like this gun got moist.

Trying to remove the valve tube assembly.

It should come off now…

Pushing out the pin that retains the barrel release lever.

Well it came out.
Only two more posts…

Crosman Trapmaster 1100 Disassembly, Part 3

Yes, there’s a ton more. I think this will probably hit 6 posts.

Another shot of the action.

This lever opens up the breech by pushing the barrel forward.

The extractor.

The trigger looks like a good place to start with disassembly.

Simple trigger.

Remove the power adjustment assembly by unhooking the spring.

It’s a stamping and a screw.

Power adjusting lever.

Removed. I don’t know what that gunk on the screw threads is. Could be silicone.

Sear spring.


Lifting it up allows the safety to drop out.

The spring.

Time to remove more screws.

The barrel comes out now.

Barrel guide and spring.


Slid off.

A C-clip holds the “barrel sear” on.


Removed.
More to come.

Crosman Trapmaster 1100 Disassembly, Part 2

On I go…

The forearm shows just slide off of the tube, but it was stuck. Really stuck. And nothing else can be done to the shotgun without removing the forearm.

I made a plastic plug to protect the tube (more on this later).

Excessive hammering and I got it to move a little.

More hammering until my biceps swelled up to the size of Popeye’s.

I had to make a longer plastic drift.

Dang, still tight.

Finally got it back far enough to open the action up, but it’s still as tight as ever.

I removed some screws.

The only piece that sprang up was the power adjustment assembly.

It goes here.

A shot of the action. There will be more… Notice the stock nut.

Another shot.

And more.

The small rubber plug fell out that functions as the extractor stop. It fits in that recess.
One more for good luck.
More to come…

Crosman Trapmaster 1100 Disassembly, Part 1

I worked out a trade with a friend for a Crosman Trapmaster 1100. I’ve always wanted one because it’s a shotgun and shotguns are fun. I also got the trap and clays, which I’ll show when (if) I get this thing resealed. In any case the shotgun needed disassembly, seals and cleaning.

The Trapmaster. Even the name is cool.

The nameplate.

Other side.

Bottom.

Gas cap.

It’s a toggle piercing cap. Bottom CO2 cartridge is pierced when you screw it down, top is pierced when you toggle the lever.

Two old cartridges.

The butt plate was nasty and the screws are rusty.

#3 Phillips bit.

Screws very rusty and one was loose in the hole.

I’ll have to plug the screw holes and redrill. The big hole is to access the stock bolt.

Butt stock removed.

Loosening the front bearing clamp.

The setscrews bear on the bearing ( that the barrel slides in).

Two setscrews and the clamping screw.

Plastic bushing is the bearing.
Much more to come…
