Husqvarna 460 rancher chain issues

[Oakleerulez]

Hi all,
I have a 5 year old Husqvarna 460 rancher I bought brand new. It has never really impressed me and about after a year or two of use, the oiler had to be replaced under warranty. (it was not giving oil to the bar).
It is my first saw, so i could be doing something wrong, but I always seem to retighten my chain atleast once per tank of fuel, and every now and on a couple occasions it would throw the chain. I suspected maybe my bar was the problem, so i purchased a new bar and chain.
Chain: https://www.amazon.com/gp/product/B07VFKPQQX/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 3/8 .50 72
Bar: https://www.amazon.com/gp/product/B000BQUJSQ/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 3/8 .50 72

I put the bar and chain on, and it was AMAZING. My saw had never cut this well, ever.

I rand about 3 tanks threw it, stopping 2x per tank to retighten the chain. Then this morning after about half a tank, the chain threw, breaking some of the teeth. The bar seems to have some rough spots, so that is trashed for the time being, and the chain has some teeth missing.

Am I doing something wrong? I am super frustrated at this point. Thanks

Pictures of your drive sprocket will help eliminate it as part of your problem .

Not bad at all.
What's your procedure to tighten the bar/chain?

 

[Oakleerulez]

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.

You have steel touching and spinning.
You'll have wear,IMHO I've seen lots worse.
Somebody will be along and correct me.

There is an Oregon rim drive kit for that saw. Also need a oil pump drive gear probably often called worm. I used one of those for an hour or so. It was at the point the bar adjuster would not go farther.

I agree with you, that's not much wear at all.

If still have your owners manual it should give proper chain tensioning instructions. I tighten mine so it is tight but can still be pulled around the bar by hand and when pulled up on in the center of the bar the drivers barely clear the bar. You are correct by lifting up on the bar while tightening. I have only thrown one chain in my 30+ years of cutting.

If u loosin the chain before the saw cools down, after the last use for the day. Then re tighten before next use your chains will stretch less through out the chains life. So when u shut your saw down for the last time each day loosin ur chain.

Sorry to resurrect an old thread but I've got one of these saws too. Last year I put a new clutch on it because the old one was worn pretty good. Now all of a sudden the chain catches somewhere and the saw completely shuts off. I even put a brand new OEM 20" bar and chain on. The engine runs fine but the chain won't even hand pull when it is loose.

Try disengaging the chain brake.

Or you could have .325 chain/bar on 3/8 drive, or .058 chain on .050 bar.
could also have a damaged drive link from new chain coming off saw in the very run and will not rotate

That isn't it i am afraid. Chain brake is fine.

I would suggest switching to a rim drive.

 

[prestoncarter680]

Not sure what a rim drive is I'm afraid. This has been a good saw except for this issue.

Also looks like the bearing peaced out
