Chain Drive gear/sprocket. Husky 359

[Dale M]

Hi..I need to ask a few questions about chain/bar/sprocket
Ive just come across a husky 359,, the bar that Was on it was a 16" .058/1,5 .325" 66dl bar.. the chain that Was on it was a .325" .050/.1,3..a number 95 oregon.
So the chain was the Wrong chain for that bar.. Now the Question is,, Is the Bar ALSO wrong for the Saw.. on the top cover of the saw it says use oregon 72LP chain..
I stopped at the Husky dealer today But didnt have the saw and told him I would Like to use the same Bar/Chain combo that I have on my 350 and have a spare of each which is a 18" .325" .050/1.3 72dl.. He said if the gear/sprocket on the saw is a 325" sprocket then that would be fine,, He didnt see the saw, But said Put the bar and chain on and pull it around by hand, if it doesnt bind its ok but if it does bind then it has a 3/8 sprocket and the gear would need to be changed.. I did this and it seems smooth/no binding.. Is there a way to tell what size sprocket is on the saw by just looking at it?? Im sure if you have seens lots then you know the difference by sight but I havent,, Id like to get it right..

Also,, How do you tell if this is the ecotec engine? and if it has a catalytic muffler? id like to do a muffler mod as I did on the 350 and heard its different process?? if its a catalytic muffler.. if the serial number helps then here it is 503917503L.

Thanks Guys for your Help. I appreciate it.

you can put any gauge chain on your saw provided the chain and bar match and the bar is the correct bar mount. It sounds like all you want is a 18" .050 .325 bar for your 359. But the chain on the 359 now is a narrow kerf chain on a standard kerf bar. What model number chain do you have on the 350? How does the 359 cut as it is now? If the chain on the 350 is a NK chain as well then that is what you would need on the 359, but I think the 359 is on the upper limit for the narrow kerf chain, honestly I have never tried it. Also if you 359 does have a .325 sprocket on it is it a 7 tooth or 8 tooth?

Let us know

The chain is wrong for the bar, but the bar is correct for the saw. The bar, chain and sprocket have to match in pitch, and the chain and bar must match in gauge. Ignore the sticker, it means nothing as to the correct fit, other than recommending Oregon 72 LP, IF the bar is the correct pitch (3/8") and gauge (0.050"), and the sprocket is the correct pitch (3/8").

The 350 and 359 use the same bar mount, and the chain drive link count is the same too. The 359 can be fitted with either .325" or 3/8", depending upon wood being cut and user preference.

If the chain pulls around freely, most likely it has the correct sprocket to match the chain pitch. They normally have stampings on them to denote the pitch, but on an outboard clutch you can't see this without disassembly. You might be able to measure it with a string or something to give you a better idea, but it sounds like it is a .325" sprocket on it.

The E-Tec models have stickers denoting the feature, plus green fuel fill caps instead of grey ones.

Hi.. The chain and bar on my 350 is a 18" 325 pitch. 050 gauge. 72 dl..a number 95vp narrow kerf.
I want to also run this type and bar and chain on the 359 just because I already have a couple spare bars and chains of this size..
the sprocket on the 350 is a normal looking 7 tooth 325 pitch'
the sprocket on the 359 looks different because it doesnt have raised teeth like a normal sprocket instead it is round with slots/groves cut into it and the chain fits more into it. it has 7 slots...the 325 narrow kerf chain seems to ride perfectly into this sprocket..
I never tryed the saw with the bar and chain that came with it because it was the wrong chain for the bar so thought Id use what I already have hanging around..
Is this correct,, if the pitch of the sprocket is for example 325, you can use either a .050 gauge bar and chain or a.058 gauge bar and chain as long as both match the 325 pitch?

Thanks Again

Yes that is correct it sounds like you can just put on one of your narrow kerf bars that you have for the 350. I am quite interested how this works out, so please keep me posted. Also the 359 is more often set up with a 7 pin 3/8 drive sprocket which is equivalent to a .325 8 pin sprocket, so you may want to change it, this affects the amount of torque and chain speed that a saw has. It becomes increasingly complex when you consider that different high speed jet settings will give you more or less speed or torque. There is also room for adjustment in how the chain is filed i.e. how much top plate, hook, blah blah blah, and of course the raker setting.

Have fun

Sounds like your 350 has a spur sprocket, while the 359 has a rim and drum setup. This is a superior setup to the spur sprocket, as it allows for replacing only the rim, not the entire drum when the sprocket is worn, or to change pitch, or number of sprocket teeth.

Normally the narrow kerf chain is reserved for slightly smaller saws than a 359, as a saw of this size can normally pull regular, chisel .325" or even 3/8" chain more than adequately, but if you have the bars sitting around, give them a try and see if it works.

As said, the sprocket does not care what the gauge of the drive links are, it only cares about the pitch. A .325" sprocket will work for any gauge (0.050, 0.058, or 0.063) .325" chain. The same is true in other pitches.

If the bar that came on the saw is in decent shape and the sprocket isn't worn out, you could also simply go talk to your dealer, and get some fresh .325" 0.058 chains for the 359.

As the 95VP offer less resistance in the cut than the chains usually used on the 359, I would definitively have wanted to try it with an 8-pin sprocket, even though Oregon allways recommend 7-pin with the 95VP.

At least over here, Husky are listing the NK setup with 95VP/H30 chain as an option for the 359 and 357xp, in addition to regular .325 and 3/8".

You may also want to test Stihl 23RS and Oregon 21LP on that bar, and see which cut fastest. It should be OK to use regular chain on the NK bar for test purposes.
On the 359 I suspect that the RS will be the winner in a speed race, but you may also find that the 95VP is fastest with 8-pin, and the RS with 7-pin.....

Hi.. I checked today and my sprocket is a 325 forsure, Had a new oregon Micro lite pro NK bar and new NK chain so I put that on the saw. Was bored at work today so also did a muffler mod . Put it back together, set it abit richer and started it up, Wow does it scream. All I had to test it on was a small 6" pine log.It flew through it, couldnt tell you put the bar against the log.it just zipped thro. I never ran this saw before today so I cant say how much of an improvement the 325 bar and chain and muffler mod made but comparing it to my Husky 351 I have its twice the saw that the 351 is....Guess I dont need the 351 anymore..
Thanks to all of you that helped me out
