Crosman Model 140 Disassembly, Part 1

I picked up a Mongomery Wards branded Crosman 140 in December, pretty cheap. It wouldn't pump up but I figured I had already done a strip of the 140 for the blog, until I checked and realized that while I had rebuilt a horrible 140 in parts and Derrick refinished a 147 stock, we hadn't actually disassembled one for the blog. So here I go.

Dark brown stained stock, plain jane 140.

A nice touch on this 140 was the plastic ramp attached to the utilitarian front sight. I'm not sure if all 140s had this or only the MW ones?

The cap on the breech was chewed up, which is a clue that someone has tried to fix it in the past.

To get the stock off I had to remove the safety and unscrew the lock nut.

I put the safety in the neutral poistion and pushed it out. You can see the plunger tip.

I used my roll pin pusher to remove the pivot pin.

The front sight assembly.

The pump arm and piston slid out. The pump plunger pulled vaccuum on the way out which means that it's ok (borne out by later use) so I won't be removing it. Which is a pity as it requires making a tool to remove the pressed on retainer.

Small dowel pin removed.

Now the breech cover.

Screw removed and cover slid off rearwards.

Rear breech screw.

I used an offset screwdriver to remove the trigger assembly.

Put aside for later.

There's a nylon bushing in the hole that had to be pried out.

You can see that someone tried to pry the cap off the breech but didn't realize the nylon bushing had locked it in.

Using the screw as a lever worked fine.

The cap is really chewed up.

Then the bolt comes out. It looks fine, or at least better than the last one.
