20" .43 gauge on a 60cc?

[oldboy]

I like the way my smaller .43 gauge saws cut. I was thinking about putting one one my 60cc 460 rancher. Would this not be a good idea? The 460 has original 3/8 sprocket. I guess I'm just worried that 60cc would be too much saw for that little chain, and it might bust it?

Thanks for any input or info.

Oregon has some new .43 20" bars. I'm not trying to be a troll, maybe it's a stupid question but I haven't found any answers researching this kind of set up, except it's not advised to used 1/4 pitch .43 on 40cc+ but I'm talking about 3/8 pitch .43

Oregon rates it's 91vxl chain at 42cc max. The 90 class whatever you find 90px most commonly is surely less. It used to be possible to search up pdf documents on the various Oregon chain. I don't recall what the minimum was for the 90 class stuff. The 1/4 0.050 25ap is for 38cc and down if I recall and the tie straps for that are stronger than the 90 class stuff. The Stihl 0.043 by 3/8 stuff has more weight than the comparable Oregon stuff. I think the 20 inch bar is a mis print for 0.043.

I would recommend getting into a rim drive and the .325NK class of chain to go in that direction. Husqvarna and Oregon both have new product out. The Oregon stuff is rated for 55cc max not sure how easy it is to get similar rating for the Husqvarna stuff. Both have oil distributing features on the drive links 95txl and SP33G for the Husqvarna stuff. Edit Stihl also seems to have a similar product which may becoming what one finds in their .325 by 0.050. From what I understand it can be identified by the word pro and or the drive links are not necked down for the bar groove. However I doubt the roll price is similar for a dedicated shopper.

The .043 gauge was designed for low power / low RPM pole saws. Whomever decided to put it on a regular chainsaw was looking for repeat business. I don't even like it on the small Stihl MS170/180 saws. I upgrade these to .050" 3/8" LP.

Not a good idea.

Smaller pitch and gauge chains are designed for smaller displacement / power saws, using lighter components. A larger saw might snap the chain.

Starting around Page 25 in this reference, Oregon lists the maximum saw displacement for each of their chains:

SpeedCut TXL (.325 pitchm 0,050 gauge) Narrow Kerf chain is rated up to 55cc, which is closer to what you are looking for.

STIHL has a newer, similar chain that is hard to find in some places:

Husqvarna:

*Narrow Kerf chains should be run in Narrow Kerf bars.

Page 33 of the file page 28 in the little red blocks. 91vxl good for 62cc. Some problems with the editing.

They have got 95vpx good for 45cc and the .325 lpx and bpx for up to 58cc.

Page 42/38 is the 90sg which kind of dates it in the bumper tie strap era 40cc max. This is the 0.043 class this thread is about.

Strangely the 3/8 low profile ripping chain is absent a displacement max rating.

Actually I am searching up pdf files easy today,
90px 90PX-ChainSaw-SawChain.pdf (oregonproducts.com)
91vxl 91VXL_FB.pdf (oregonproducts.com)

One cc difference in rating? 41cc and 42cc

put in Oregon pdf and the chain code. They are not dated that I can see.
