Cleaning Up a Crosman 66, Part 2

Well, I didn't want to do a lot of work on the 66...

The transfer port is a somewhat restrictive .125" diameter, and the transfer port seal is .140"

So I drilled out the transfer port.

And the valve. I didn't bother smoothing, polishing, etc.

The cocking lever and spring goes in.

Then the rest of the trigger group.

I stuffed all the other bits in.

Then took it all apart as I forgot the plug that retains the shroud. It had fallen on the floor.

All back together. I put a cheap garage sale scope on it, as the rear sight is missing. The front bit of the handguard is missing as well. I checked out the velocities, with 7.9 gr. premiers it was shooting at 589 fps, 6 ft/lbs with 10 pumps, a bit slow from the advertised velocity of "up to" 645 fps. With 10.5 gr. premiers I got 521 fps, 6.33 ft/lbs, and with 15 pumps 567 fps, 7.5 ft/lbs.
Not that you're supposed to pump it up more than 10 times...

So now if one of my friends reveals that they are lacking a pellet gun, I have the perfect $6.00 gift to give them.

Cleaning Up a Crosman 66, Part 1

Well, I can't always work on lovely old vintage guns...The neighbor had a bunch of BB guns he had to sell for his daughter, so I bought several for $6.00 a pop. The Crosman 66 below had a few problems. The barrel shroud was missing the screws that hold it in place, the sight was missing and overall it was dirty. So I decided to take it apart and get it back into shape.

The Crosman 66

Notice the shroud is loose and rust freckled.

I used a square drive screwdriver to remove the three screws on the right side.

And one on the left.

I popped the cap off the pistol grip and unscrewed the buttstock.

The trigger assembly. This picture is important for reassembly. You can't really make it out but there are cobwebs in the trigger assembly.

The hammer assembly comes out when the tube is pulled and the trigger parts go all the pieces...

Punching out the pump pivot pin.

The pump arm removed. The pump seal was dirty.

The small rubber seal for the transfer port was removed.

The valve assembly was pushed out the front of the tube. The pump end was really dirty.

I chucked up one half in the lathe, locked the spindle and usncrewed the other half with a vise grip. The jaws were cushioned with a thick rubber band.

The valve, disassembled.
Everything in the gun is dirty. So I'll clean it all up and put it back together for the next post.
