Low profile chain and bar?

[Stubby]

by "low profile" do you mean narrower width ways ie smaller kerf?

thanks carl

 

That and cutters not so tall ...hence lopro

Yes, but they "happen to" cut a narrow kerf (narrower than regular 3/8") as well.

 

As the "chassis" of those chains are lower and differently shaped as well as the cutters, they don't really fit on regular 3/8" drive sprockets, and the nose sprocket of regular 3/8" bars are incompatible with them (usually doesn't work at all).

 

This is a challenge on the 550xp etc - but it can be done with using a standard 7-pline drum from/for the 562xp and the standard spline picco/lo-pro rims from GB (Stihl ones only come with the Stihl only "mini" 7-spline, and are no-go on those saws, or anything else but Stihl).

 

Regular 3/8" drive sprockets are too small, and about like running the chain on a sprocket that has been worn well past its useful "life" - but sort of works if you can live with the chatter and accellerated wear.

 

Then there is the question of why anyone will want to do it at all.....

Works fine with a .325 drive and chain on a 560.

Well havent been using it that much. Its first outing was loggin up down the yard was cutting really well until i mutilated the cutters on a stone in some timber. Sharpened it back up by hand no problem but took the rakers down a touch as i had to go back a bit on the cutters but it is a little aggressive at the moment.

It's that typical new chain just been fitted syndrome!.... they seem attracted to stone and metal.

Did you notice much difference in cutting speed?

Well it the chain is good but unfortunately the nose sprocket has broken up on the sugi bar! Didn't even last a month!! Perhaps I should have stuck with oregon!!!
