Hi guys. just got a air pistol from my dad that has probably been sitting around for 20 years. I don't know the maker or model and there does not seem to be any identifying marks. Its seals leak so i would like to know what im dealing with so i can get it repaired or try to repair it myself.
The one i am interested in is the BOTTOM one

i know it is .22 cal and uses the 12g co2 cylinders and thats about it. any help at all would be great and on a side note some suggewstions for repair places near victoria bc or at least in bc would be cool too. thanks in advance
 
Well after some minor disassembly i found the patent number on it and found out it was registered to Crosman. After combing the Crosman website for manuals i now know that i have a Crosman model 600. Apparently a bit of a collectors item. just gotta get it fixed up now
 
What you have is the first true semi-automatic pellet pistol.
After you get it up and running you'll find that it likes the wadcutters best.
It is a very good find that commands a higher price due to its design.
Some like to mod them. KD

The Cr. 600 is a bit of a complicated rig to dig around inside if you are prone to prying things with big screwdrivers. There are a couple parts that cannot be got any more, and several more that are just difficult to find.

Seals, on the other hand, are mostly just inch size O rings, if you want to go to the trouble of digging out the dimensions, or contact the likes of D&L Airguns, in Canada, or Mac1 Airguns or Crooked Barn, in the US and ask about seal kits.

When you take the side cover off the trigger mech, take a close up picture that you can use to put all the parts back together correctly with. There are three levers in there that have springs on them, IIRC, and the locations of the springs are not very intuitive until you really get to know the layout.
You will need a #4-40 screw, IIRC to pull two pressed in studs that lock the valve into the main body tube. Marked in the Crosman diagram as parts 600-36, and 600-81, retaining pins. You will need to remove the valve body, to get at the orings that allow the semi auto part to cycle.

There is a copy of the shop manual being sold on fleabay, Item 300397986940. You may be able to find it somewhere online.

These are fun guns to shoot, a bit picky about ammo, and can be tuned up to run pretty well. They are a bit hungry for the CO2 though, and if you want to shoot a lot, a paintball adapter is a good plan.

Oh. The extended mag in the picture above, is worth as much, if not more, than the pistol it's on, which has a substantial value in its own right.

Fun gun. I traded mine off a few years back, after rebuilding it after it had suffered the ministrations of a hack with a coarse file and a drill press. Should have kept it!

It may be best to send it to John at D&L Airguns to reseal.
I just had a look at the schematic and it aint as easy as a first year 760.
But if you're really into adventure, I might be able to send a shop manual. KD
 
im gonna give D&L a call on monday. They are just over on the mainland so it should be easy to get the gun to them.

It does shoot fine just leaks air. The main leak sounds like its coming from the piercing pin in the knurled tube cap. The second leak sounds like it is coming from where the air hits the pellet(chamber?) right before it goes into the barrel.

The exploded view from the crosman manual make its look really complicated and even barring that i have seen a partial takedown on a blog. I do not have the tools or know how for that kind of thing it turns out
 
Yes you do.

You have enough brains to ask questions, enough net skills to get here, therefore you can probably find other online info, and I'd bet you have a screwdriver around the house somewhere, or can get one. And a set of allen keys (hex keys), you will need one for the shuttle that feeds the pellets from the mag to the barrel.

It really is stuff that can be done at home, but by all means, if you want to keep the economy rolling along...:D

A 600 is a bit fiddly compared to a 150 or 2240, but it's not really all that bad, if you can take some time and have the patience to look the stuff over and understand how it works.
