Husqvarna 460 won't spin once tight!

[swankerme]

Please help me understand what's going on!

I got 5 chains sharpened and shortened. First time running saw with resharpened chain, the saw bogged down and won't spin chain. Began troubleshooting...

Purchased new 20" bar and 20" chain. The chain lines up and spins with no problem when loose. As soon as you put the cover on and tighten to 1 finger looseness, the chain will not spin. I can't see anything binding or preventing it from spinning.

Chain break isn't locked up (had that problem before, this is not that).

Could it be a bad sprocket/bearing?

Sho us a pic or two of that shot sprocket!!!!

Shortening 5 chains is the first clue.

Problem is, the bottom side of the chains are likely boogered too. So put up some pics of those.

Don't run the new one on it!!!

Pics????

 

[swankerme]

Why not run a new chain on it?

I don't see burrs on the sprocket.

You need a new spur sprocket / clutch-drum . That one is well worn .

OMG, Fish nailed that one, the chains cut through that spur “like butter”.

You probably wasted your money on the link removals too, good thing you didn’t have them sharpened.

Nah....
We won't fall for it......

Anybody that green wouldn't have the sprocket in his hand.. We won't bite......

Googling a picture of what a sprocket is *supposed* to look like, mine is indeed worn. Mine is so worn that I thought those grooves were supposed to be there.

Green I am, but I ain't afraid to learn! Thanks for the advice and gentle harassment

Lol that is by far the most worn sprocket I have ever seen!!!! Wow hall of fame that one is there!!

This is clearly why it won’t work. Get yourself a new one.

Hey look at it this way, you have figured out the problem and you can go cut wood again! We all start somewhere!

now ya know what a good cutter hardened steel is!

That's bad, but have seen worse. Cut in half worse. Changing a sprocket like that with new, will require new chains or you will destroy new sprocket.

Yep this guy is definitely a hands down winner . I didn't think a sprocket could get to be that worn down.

 

[HarleyT]

OK, how did you take the sprocket off?
Many of the guys here have trouble doing that.

Impact and correct socket.

Get a rim and drum and forget about it.
