Crosman Trapmaster 1100 Disassembly, Part 6

Last disassembly post, next post will be me trying to fix it in my typical hamfisted manner.


I made the plastic drift even longer.

Finally got it out. Look at that rust(?) on the barrel.

Or glue? Maybe someone though the forearm was loose and tried to tack it in place?

It’s interesting rust.

The tube seems ok although dirty inside.

The piercing cap should come apart easily.

Ok, I can remove this.

Bent my much modified tool.

Finally unscrewed the top piercing pin. But I was unable to go further. The piercing cap pieces are stuck together. I’m soaking them and may need to apply heat. It’s not as bad as some guns I’ve taken apart but a few issues will need to be dealt with.

A little longer…

Just two pieces left…

Rear cartridge piercing.

I braced it in a vice and unscrewed it.


Well two pieces came out…

The o-ring has an old nick.

The piercer won’t come out…soaked it in some WD40.

So the valve tube assembly end won’t come out because one screw is sheared off. I drilled it down below the surface.

Finally. Man, look at that rust. I was hesitant to take the Trapmaster apart as it looked ok, but clearly it needed this.

Even the o-ring is rusty.

Valve spring.

Valve assembly.

At least the valve seat looks good.

Valve parts.

That seal looks ok.

Finally was able to jimmy out the piercing pin with a broken dental pick.

The screen retainer was so rusty it broke when I removed it.

Dang, that’s nasty.
One more post…

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…

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.
