I have a husky 445. Its running .325 x .50 chain now. I assume the sprocket is just for 325 chain, like I can't swap to a 375 x 50 bar with out changing sprocket can I?
 
Anyone??

Crickets!! Chirp chirp.
 
Chainsaw drive sprocket pitch, bar tip sprocket pitch, and chain pitch MUST match. All three.

As far as gauge goes, bar and chain gauge MUST match. The saw's drive sprocket is gauge independent.
 
K thanks. That's what I thought. So if u have a hard nose bar as long as its the same gauge it will work I guess cause. There is no sprocket. Mother benefits. To hard nose I guess?
 
Correct, hard nose bars have gauge to match with chain gauge. They don't have a pitch. The benefit of a hard nose is that there's no sprocket to jam or fail when cutting really nasty things (gritty, sandy, etc.)
 
Plus u can switch pitch!
 
Good point.

It's been years since I used a hard nosed bar. I like the reduced friction of a sprocket tip.
 
It's much more fun to say "sprocket." :)
Actually there is a difference. My Remington SL 9 has a roller tip bar. Can run any pitch.
