Husky 455 with 20" Oregon Rim Sprocket, Bar and chain is LOOSE!!

[russrock7]

Hi,

I picked up a Husky 455 from a guy used in really good shape. It needed some fuel lines and stuff but has a good looking engine.

The problem is the chain is loose and there is no more room to adjust it tighter!!

The bar is a 3/8 .050 20" Oregon bar(200SLHK095), a 3/8 .050 20" chain 72 links with '80' stamped on the guides(it still measures 3/8" between rivets) and a 3/8 7 tooth rim sprocket.

The guy said "Oh, the chain probably just got stretched", but it measures correctly.

So do I get a new chain? I looked up the bar and it should be OK on the 455.

I can't find anything on the site and Oregon Bar Match doesn't give me any insights.

Thanks for any suggestions

P.S.
I just found another site with some details on the bar. It says 20" Laminated sprocket nose bar .050" gauge 3/8" 70 DL
Is the chain .325?!?!? I can't tell.

these things sometimes dont oil a 20" so good, then the chain wares until the bars out of adjustment

 

[cobey]

try the search function too, there has been some good info on these saws

The chain is a Husqvarna 3/8, I just measured it again. The bar has '72DL' stamped into it.....

So I'm stumped again.

Heck yes they sell a 20" bar in both 70 DL and in 72 DL. I have found it to be very common. So just get a chain with 70 DL in 3/8 .050 and you will be good to go.

 

[russrock7]

I think I need to call Oregon and ask them if their '72' stamp is correct

Our 455 with the original Husky bar takes a 72 dl 3/8" chain. fwiw.

 

[cobey]

so the people having trouble with these could need to run a 70 driver chain?

How much play in chain?

Measure again with the chain on the bar, pushing the 2 end cutters together, then measure after puling them apart. I had a barely used chain that was on a second hand saw, and the rivets were so worn I could move it nearly the full length of a cutter over about 6" of chain.
There was no adjustment left on that bar either, but no point pulling a link our two out as it will just booger up your drive sprocket.

Count them?

'Oregon 72' is a type of chain; .050 gauge 3/8 pitch.

'DL' would refer to the number of drive links.

Many of the Poulan, Husqvarna, Echo and John Deere saws run a 70 Drive Link '72' chain on a 20 inch 3/8 bar.

The stamp is on the bar.

There is a small amount of play with some of the links. It might have 1/4 inch of difference through the length of the chain.

I have a call in to Oregon. Hopefully I will hear something next week. The confusing thing is that I've seen a few different references about the number of links required for this bar.

got a pic of the bar mount area that shows all the numbers? that would help.

Not Husky!

Are you sure you don't have a standard/large 7-spline rim on a small 7-spline drum - or is the sprocket a spur?

 

[ncfarmboy]

Get a new 3/8"x.050x72dl chain that one is shot. That bar takes a 72dl chain.

The bar, rim and chain. Husky 20" chain, 72dl (yes, I counted them ), '80' stamped on it (whatever that means).

The bar adjustment ALL the way forward

The slack in the chain. It got even worse after I ran it for a minute.

Maybe I'll go to Lowe's and buy a chain. If it doesn't fix it, I just return it!

I should have taken some pic's of this saw when I got it. It's a 2006 model but it had dirt in it from 2003, that's how bad it was. It got a replacement chain break spring, I'm guessing the prev owner opened up the chain break and the spring sprang out but they didn't put it back in, its kind of a b*tch and I always injure myself at least once doing it. Needed a few fuel lines and a filter. Got a new decomp valve as the original one was a little loose.

Once this chain problem is resolved I can finally get it on Craigslist.


I appreciate all the positive suggestions and advice from you all. What a great resource for nubs like me!

I hate H80 chain almost as much as I hate safety chain. Rakers are a PITA to get right. I will use it cause I'm frugal. Frugal sounds better than cheap.

[russrock7]

So you recommend an oregon chain?

"Safety chain" is exactly what it is - Oregon Vanguard.
