Chain self tightening

[J.w Younger]

I installed an RS chain on the same bar and it does not tighten as I spin the chain.

That's curious that it doesn't do it with the other chain. Not sayin you don't need to replace the rim, you do, but you might try flipping the rim just to see if it makes a difference. If it did you could use up them 2 chains and put the new one on with the new chain/s.

Actually to me that makes sense jw I can't stand to throw anything away lol but yeah you'd be usin the "good" side of the rim for the chain givin you grief I'd hate to throw a chain away that's why I kept runnin mine that was trashed had to get every edge outta that chain possible

Sorry for the delay, had to load and split the cottonwood that killed my chain.

Picked up a new rim, 4 more on their way.

RS3 on the right, RS on the left. I'm going to take a dremel to the tie straps bearing surface and remove the flash from the edge and try it with a new sprocket. I'm using the brand new sprocket with a 16" setup I just purchased.

I'm thinking that the obscene amount of dirt in this cottonwood I cut was a large factor in this problem. I cleaned it out the best I could before each cut.

The tie straps are almost to their wear indicators while I have quite a bit of cutter left. I'm also guessing that the tie straps wore down due to grit much faster than the drive links for whatever reason. Maybe the ratio of drive links to tie straps is way off and as the drive links move forward into the sprocket tooth they drive themselves away from the rim causing the chain to tighten.

That or is was Professor Plum in the study with a candle stick? My brain is fried from over thinking this. New sprocket, I'll dress the edges of the drive links, and see what happens.

If it is shot, could anyone here use the cutters or parts for their own chain build?

I hate to recommend something "wrong" but jw advice on flipping your old rim over is what I'd do to save that old chain that way you don't wear your new rim out

 

[jakethesnake]

What ya doin with that there dirty log

I suspect that it is the combination of the worn chain on the worn sprocket causing your problem.

A new chain on a worn sprocket and a worn chain on a new sprocket might still work, if you want to squeeze some more life out of that chain.

Or, run it on a spur sprocket.

Can I get a spur for the MS362C?

 

[jakethesnake]

Before I went through that I'd trash that chain But I'd still try that rim flipped over a spur sprocket is a downgrade

 

[Philbert]

Can I get a spur for the MS362C?

Probably not. But might still work on someone else's saw if you decide to toss it (BTW - I am not asking for it!)

It was on my bosses property where I cut firewood. He asked me to get rid of it. Ultimately I had a feeling it would cost me a chain at least. I split some of it tonight, garbage through and through.

I threw that sprocket in the box with its chain, I'll throw it back on when I dress the chain and report back if the thing still tightens itself.

 

[jakethesnake]

I keep my shot rim with that chain in my pictures if a root happens to piss me off or the like I'll use it once more

 

[jakethesnake]

Or if I find a dirty cottonwood log like the one you fought lol

Philbert runs a homeless shelter for poor unloved chains that's what he was gettin at I hear he even likes ones with half the teeth missing. Very knowledgeable fellow on saw stuff

If the drive rim is the culprit, being a 7 pin and a .375, the chain should go thru tight and loose cycles every 2.5-3" of movement.
2.625 by my math.

Thank you for the kind words.
But I am not asking for his chain!

Lot of life left on those cutters. Someone could run it, even if the loop needs to be resized. Should run on a clean rim or spur sprocket.

If you have to remove a drive link on a 72 drive link loop you've got a lot and i mean a lot of egg shaped holes and worn rivets.But i'd take 8 out and run it om my dolmar if it didn't have them bumps on it.

Looks like lack of bar oil ?

That probably is true to a degree. The dirt would clog up the bar, so I would stop mid cut and Rev the saw against clean wood, it would shoot chunks of dirt and bar oil out until it ran bar oil clean. Had to repeat that a million times so I'm sure it was run dry a percentage of the time.

Holy Chit, yous bringin maths into this. Could you explain that in redneck? I'm not nearly that smart so I'll take your word for it.
