Anyone familiar with this rifle?

If you want to replace the parts in the 75A-1 under lever the B3 kit from archie might work. $17. It has 2 breach seals that might work or find a faucet washer the same diameter. The main spring might work. But the piston seal is plastic and snaps over the end of the newer model pistons. A B2 leather piston seal might work. If to small soak it in some oil or silicone oil or lint seed oil to make it swell. Archie sales B3 leather piston seal separate if he's not out. He sold separate B3 breach seals but I think he's out. He sales the B3 and QB57 kit but not the B2 kit like PA. Click parts then B3 to see what he's got in stock.

If you are missing a stock screw on the break barrel you can take the other to Home Depot or Lowes and find another but it has to be the same length(not too long) or it will get in the way of the cocking linkage. If you're missing a bolt that hold the cocking linkage to the barrel, it was probably a rivet originally. A bolt, nut and lock washer might fix that.

Can't mention his real name in this blog but google chinese air gun parts and he'll be at the top of the page. I've bought lots of gun and parts from him with no problem. Later.

Ok, got the kit, what do I soak in and how long do I soak these leather seals? Thanks

The little breach seals for the break barrel don't need soaking. Put them in. It might take two. One to shim and one tostick ouy a little and seal rub a little oil on the outside. If it want go in easy I put a folded shop towel over the the sael and tap it in.

The leather piston seal if it's a little to small soak it over night in oil, silicone oil or lint sead oil and wipe it off good it. it should have swelled and fit a little tighter. The gun will blow oil  for awhile.

Thanks! Always shoot with a pellet in breach though as always correct? Meaning don't ever dry fire the gun even through the break in period of the new seals?

[avator]

Correct.. never dry fire a spring powered gun.

My light kit for chrono will be here tomorrow so I'll be able to run some shots across it and see what kind of numbers I get. Pretty excited to see the results. This was my first rebuild on a springer, and quite a learning experience, but fairly easy rifle to work on.

[lefteyeshot]

The break barrel or under lever? Did the B2 or B3 kit parts work or help?

[Tims229]

I'm the owner of the break barrel, and yes the parts worked and I'll see how much they helped today.

[Tims229]

So now I'm getting upper 300s fps with it. Before rebuild was closer to 200, I'd say that's an improvement.

[lefteyeshot]

If you got a bunch of grease and tar in it clean it out and just a dab of molly on the spring ends and see what it'll do.

I picked up this old B2. the plunger seal was stripped out and stuck in the chamber, someone probably quit shooting this years ago. Re-threaded the plunger and a new screw and it's firing pretty hard again, the seal was hardly worn so it happened early in the gun's life, probably just sat in a closet. Mine is .22, nice and quiet and probably doing about 450 FPS, goes through cans and tins easily. I like getting these cleaned, lubed, and polish the parts so the sound like a much more expensive gun, lots of fun

Nice looking rifle Centurion
