Husqvarna 460 rancher chain issues

[Clyde85]

With a rim drive the rim sprocket is separate from the drum so you just have to change the rim when it is worn.

I found my problem 8-0

At least it's not that worn.

Right? That one was new as of last fall I think.

Do you know what happened exactly?

No clue. I was running the saw and suddenly CLANK and it shut off. I knew it wasn't the brake bc the engine would still run. I suspect the pin bearing failed causing the clutch to go askew and thus the tooth on said clutch left the building. Who knows where it wound up.

Thats not bad? it looks like it has some pretty gnarly grooves that arent supposed to be there.

Nothing crazy, but I tighten the chain just so it barely touches the bar, then tighten the nuts as much as i can. I make sure the chain is still the right tension and start cutting. After researching a bit on these forums i realize that i should probably pull up on the bar whilst tightening to maintain the correct tension.

Sounds too loose. With the short bar that would be on a 460 the chain should never come off.
With bigger saws and longer bars especially when limbing it can occur very occasionally
