Husqvarna 460 won't spin once tight!

On that clutch?

Yes.

At any rate, the question was for the O.P.

 

[HarleyT]

Doesn't that clutch look like this?

 

[SEAM]

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.

Nah, those chains should be fine - nothing left to drive links on that sprocket

It was very easy to take off, actually. Take out spark plug, grab a nylon rope, loop it, feed it into the chainsaw. Rotate clutch so the piston locks. Hammer and screwdriver to loosen and unscrew the clutch.

 

[SEAM]

Never ever use a hammer or any other impact on a crank with the piston stopped ...

What causes this much wear? Is this normal for the two years I have been sawing with it? Am I running my chains too tight?

Also confused, am I okay to use my old chains or should I just stick with brand new ones? We'll put in a new sprocket this weekend.

Wear is normal. Usually the sprocket gets changed long before this much wear is visible.

 

[SEAM]

It is usually best to replace sprocket and chain(s) as a set. A worn sprocket will damage new chain and vice versa...

Why? Does it put a hole in top of piston?

 

[SEAM]

Puts too much momentary strain on the shaft/crank/bearings/rod. You usually may get away with it, and a rope is fairly safe, but I have seen damaged (bent) rods - mostly on small Stihls and rods that are not forged. When stopping the piston removing the clutch without impact is the best way imo.
An impact (driver) against compression is always preferable.

They make a tool for that. It looks like two slightly triangular tabs welded onto a 19mm bolt head.

You can make one with an old socket and angle grinder.

That’s what I did, works well!

The factory tool is only $7.

Both an overly tight or loose chain may accelerate sprocket wear. Others may do it differently, but I tighten it as tight as possible but still see the chain move on the bottom of the bar when I pull up on it on top of the bar. It needs to move freely when you pull it by hand. Keeping the chain sharp will reduce the stretching that occurs when it gets hot.

With the cost of chains, it might make sense to use up the old chains if they work OK with the new sprocket, then replace the drum again.

That's the way slackers do it.

 

[Capitalist]

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

I cut a ring sproket in half once.... Once!

I have a bucket full of old sockets and an angle grinder, it cost me nothing!

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

Don’t sweat not knowing it was worn . I’ve seen worse in my shop .
Think of it as a learning experience . And that “ Experience is that thing you get ,right after you need it . “ .
