NEED HELP - Stuck Threads on Gas Cylinder Nut of Baikal MP153 / Remington 453 Spartan

Mike1234 · January 6, 2012, 12:49 PM

A neighbor of mine has a Baikal MP153. If you don't already know it's the same as a Remington 453 Spartan. He bought it used through GB. Overall it's really nice but the gas cylinder nut is frozen solid.

I'm seeking forum advice for him because he doesn't have internet service at home.

How can he remediate this problem? Could he safely soak the entire gas system in Windex or maybe just a weak solution of blue Joy dish soap? None of the cleaners he's tried are working. I'm sorry but I can't remember what cleaners he tried but I do know they're all oil-based... not water-based.

All advice is appreciated.

did the shotgun come with the proper wrench to adjust the gas system?

Mike1234 · January 6, 2012, 01:03 PM

^^^ Yes, he has the correct wrench. That nut is stuck solid. I have somewhat larger hands and I couldn't break it free either.

I'm thinking it's been shot so much without it ever being adjusted or cleaned that the carbon locked the threads. This is why I'm asking about soaking in a water-based solution... to dissolve the burnt powder.

Water-based cleaners are great for black powder guns*, but I'd avoid them in modern arms -- guns and rust are poor partners. What happens if you use the water-based solution and the nut doesn't come free? I don't have a clue about the Bailak, it may have a heat sensitive thread lock. Has you neighbor tried warming the culprit?

*Yes, it's true, some shooters claim to clean their assembled percussion revolvers in their dishwasher.

hmm maybe try some bore solvent, maybe some thred buster... i would also stay away from the water based cleaners. personally i own one of the spr453 and have never had this problem with over 4k rounds through my Baikal

Mike1234 · January 6, 2012, 05:05 PM

Okay... no water-based solvents.

Please post your suggestions for the very best oil-based penetrating powder-dissolving oils.

BTW, he buffed all the moving parts today (just minor polishing) and, I must say, it does "feel" better when manually cycling.

Can we safely use a 50/50 mix of Marvell's Mystery Oil and toluene? Are there any plastic or rubber parts to worry about? Will this damage the finish or factory lettering?

Mike1234 · January 7, 2012, 04:39 AM

What about... Robla Solo Blackpowder Solvent?

Doug B. · January 7, 2012, 05:18 AM

Try a 60/40 mix of Dexron transmission fluid and acetone. Let it set for a day and it will more than likely break free.

Mike1234 · January 7, 2012, 09:04 AM

Or at least it'll shift smoother.

We'll give that a try.

Try some kroil, it ain't cheap but I have yet to see something it couldn't get unstuck.

Try some PB Blaster. I've had pretty good luck with that stuff.

Big ol' +1 on the PB Blaster. It's the best I've found to date for unsticking stuck metal doohickeys.

Mike1234 · January 7, 2012, 04:47 PM

Here's the plan. He's going to try diesel fuel first and if that doesn't work then he'll try PB Blaster... I'm going to buy some regardless.

Mike1234 · February 15, 2012, 07:50 PM

UPDATE: My neighbor never got around to trying diesel fuel and neither of us mixed any Ed's Red. However, I bought a gallon of BP Blaster the other day and soaked his gas valve for 24 hours. It broke loose with very little effort tonight. We sprayed some cleaner through it and the run-off kept coming out extremely dirty. So we adjusted the gas to the opposite side that it was delivered and I'm soaking it another 24 hours in BP Blaster tonight. We'll use the BP Blaster we soaked it in to spray through the valve tomorrow night as we work the adjustment back and forth.

PROBLEM SOLVED... THANK YOU!!
