gixer1 Posted February 28, 2011 Report Share Posted February 28, 2011 Does anyone know if the drive sprocket on a 240E Husky chainsaw will fit both a 3/8" and .325" chain? I am looking to change my current 15" bar and 3/8" chain for a 13" bar and .325 pitch chain (.050 gauge) I'm guessing the saw will gain a little more power with a shorter chain driven round a shorter bar and i very rarely cut anything over a foot dia max.

hillmouse Posted February 28, 2011 Report Share Posted February 28, 2011 (edited) I am fairly sure the drive pitch is the same as I use both a 12" .325 bar and chain and an 18" 3/8" bar and chain on my 268XP with no problems. Just give a proper dealer a call and they will give you a definite answer. Edited February 28, 2011 by hillmouse Quote Link to comment Share on other sites More sharing options...
Diceman Posted February 28, 2011 Report Share Posted February 28, 2011 I actually went the other way with my Stihl and added about 3", I didn't notice any loss of grunt at all. Don't want to be a smartass but if you never cut anything more than a foot do you really need more power or do you just need a sharper chain?

gixer1 Posted March 1, 2011 Author Report Share Posted March 1, 2011 Diceman, know what you mean but at the minute it has a pixel hardwood chain and that seems to blunt quite quick so I am going to try the .325 and a shorter bar combo as a) it's easier and faster to sharpen B) should be easier for the saw to drive and c) should be an easier combo for the oil pump to deal with. That's the theory anyway! Regards, Garry Quote Link to comment Share on other sites More sharing options...
Conygree Posted March 1, 2011 Report Share Posted March 1, 2011 (edited) Dry hardwood will blunt chains quicker, I would tend to stay with the original chain size, but most work is done by .325 chains on short bars. cutting is all down to how sharp your chain is and any bar wear to stop the chain being slack in the grove. I have chains from the smallest on a MS170 to 3/8" and if set up well they all cut well. You should be able to cut with no hand pressure on the top handle. The .325 is a bit safer to use against the 3/8 chain as it snatches less especially cutting fire wood in a heap where if the chain touches a small log it can send it back into your leg ( I know one guy who had his leg shattered this way) On rim sprockets they will fit all widths both Stihl & Husky, well they do on mine.

Catweazle Posted March 1, 2011 Report Share Posted March 1, 2011 Make sure your logs are clean, the slightest trace of mud on them will blunt a chain that would otherwise last for ages. When felling, try to land the tree across another trunk, like a bench, this keeps them at easier height to work on and out of the mud.

Its what pro climbers use on 35cc climbing saws with 12" to 16" bars. Drop the bar size if you can. If you do want to swap i think you'll need to swap sprockets. If its a rim sprocket its only a few quid and easy enough to swap. Spur sprockets are a bit more expensive. Quote Link to comment Share on other sites More sharing options...
eagleye Posted March 5, 2011 Report Share Posted March 5, 2011 3/8 P chain is a better bet if you ain't used to chainsaws less risk of kickback try a micro chisel cutter rather than full chisel in theory not quite as sharp but stays sharper longer and check your saws oiling ok plus if you sharpen your own chains check the depth gauge as well to high takes less wood out 12 bar will do a 24in trunk with reduction cuts eagleye Quote Link to comment Share on other sites More sharing options...
