Chain / sprocket question

[troutfisher]

I have 3 saws that use 3/8 lo pro chain ( oregon 91 chain), I buy this chain by the roll. I would like to be able to use this chain on my 346XP. I have a 3/8 rim for the 346, but the rim is meant for Oregon 72 or 73 chain.

Can I run 3/8 lo pro (oregon 91) on this rim?

I will adapt a 16" bar from a 136 to fit the 346.

As far as I know 3/8" is 3/8"... no matter if it's low pro or not.

Thats what I wanted to hear.

The drive tangs or different size, so I don't think it will be an optimal solution.

Stihl use a special spur sprocket on the 660 Logosol, for PMX chain........

Yeah... but who in their right mind would run low pro on an 066 Niko???

Isn't 3/8 lo pro actually .365" or something, not .375"--at least at Bailey's, thats the case if you look at the chain.

That's what I've come to understand from this site, as well. I've not measured for myself, but I DO think the two "3/8" chains are different in TRUE pitch.

TF, I have ran a 3/8LP bar and chain with a 3/8 rim sprocket without any problems on a 60cc saw before.
The only difference I noticed was the drive link size Big v/s small V v, same distance between drive links.

Look at the drive link counts for a reel.

100’ Reel 30LP Saw Chain (.365 x .050 - 1640 Drive Links)

100' Reel of Oregon 72LG X(.375 x .050 - 1640 Drive Links)

I wrapped some chain around the rim, It seems to fit well, but the drivers are not as deep as the 73 chain (like you said, big V vs. small v). I'm gonna try it, thanks.

They are the same pitch, both are actually .367.....


...and .325 ain't .325 either, more like .313 or so, I think.....

Millers and log house builders, chain breakages are known to happen, at least among the last category.........:greenchainsaw:

Stihl sells the 660 set up that way (also) here, as the MS660 Logosol.......

066 Niko???

Gary

What's Niko?

Sawtroll.

The same bar/chain combination is used by Logosol (www.logosol.com) on their electrical E4000 / E5000 / E6000 powerhead for the Logosol portable mill. Bar / chain can be used directly on the Stihl 066/660 also sold with this system.

I have this mill myself, and for 5 years still no chain break has been seen. I have the E5000 powerhead, and it delivers 11-13 hp peak.

Just curious Esbjug, you have to have access to wood that is larger than what you have described, to have use for a 372xp, and a mill........

The mill is very nice for any building project! I mill about 50 m3 each year, mostly spruce.

The Husqvarna 372XP really not needed here, but is is great for felling large pine and birch (40-70 cm root diameter) found on my farm. I also have some maple trees here. This saw is also great for firewood too large for the firewood processor. Very fast compared to the 50 ccm range saws.

Yes, I know - I have a 372xpg (not even run in yet, as winter suddenly appeased right after I got it) - but you described your wood as much smaller in one of your posts, so I wondered........

We should have been at the cottage, sawing wood now, but Witchy is ill, so no-go.....

Most of the firewood I produce, is in the 10-40 cm diameter range. Up to about 30 cm, the Hakki Pilke (70 cm blade and single sylinder splitter) is used. I also have a Moelven (vertical 125 mm sylinder, 22 tonnes) combined cutter and splitter. A nice machine, doing a lot of pain to the firewood! Great for fast drying.

Was just out using the 346 XP cutting what was left from last weeks milling. I also have to start the 372XP later today to cut some large birch.

Something like this one?

From another tread:

This picture was posted in another tread, but it was really meant to be here.

It shows the Queen with 20" bar, and its first victim - the tree went down pretty fast after the picture was taken.

SawWitch is holding the saw.

It has only about 3 tanks trough it so far, but it is markedly stronger than initially already. The still have only one piston ring here, I believe....

 

[Esbjug]

Yes, I have trees of that size and larger! And smaller ones as well!

I guess I have to bring with me my digital camera, and take some pictures showing my work.

One of my projects later this summer is to prepare for a new road in my forest. A lot of timber has to be cut down. You have to get yourself down south to take part. I guess the witch rides her broomstick in the air.
