Cooper rifle bolt disassembly instructions

[BadSquirrel]

Anyone have info on how to disassemble a Cooper model 38 bolt for cleaning? My search attempts have not been successful. I had a couple light, no fire, primer strikes on CCI 450’s so thought might help to clean and lube the bolt/firing pin. Second attempt on the misfired rounds resulted in successful detonation. Rifle hadn’t been used for several years before I got it.

Kleinendorst makes a tool most likely. Mine says for model 22, 52, and 54. Mines a 54 repeater and it works great.

Does the bolt on a Cooper model 38 disassemble in the same way as a Remington? I haven’t been able to find any videos of it being done.

de cock the bolt and unscrew just like a remmy

Thanks. I must have ordered the last one they had in stock.

Don't recall it being like a Remington at all. I do recall that after you de-cock the bolt (padded vise works well):
1. tighten the set screw in the hole on the side of the bolt shroud. Hopefully it's still there. It takes a 1/16" allen. You tighten it to keep the firing pin from moving when you,
2. remove the flat blade screw from the rear of the bolt.
3. loosen the 1/16" set screw but don't loose it.

Everything should un-screw now.

For re-assembly, I use the tiniest bit of licktite on both screws. You need to tighten the set screw to kip the firing pin from spinning when you assemble.

Re-cock in the vise

oh, and you won't need the tool you ordered (unless you have some Remingtons)

Well that sounds more involved. Anyone have a view video of the process they could share?

I suppose needing 2 tools is more involved than needing 1. It's pretty simple.
Your light strikes could be a broken spring or a worn out one. I once had a similar problem and called Cooper. They sent me a new one on their dime. Bet that won't be the case today. The old spring was a good 1/2" shorter than the new on. Just worn out.
If your bolt has not been maintained it can be pretty gunked and might require putting the bolt in the vise and using a strap wrench to unscrew the shroud.You can make a strap wrench using most anything but I find wet leather works great.

I’m not sure if you can pull against a square table edge and put a dime in there like a Remington, haven’t even thought about it.
