Husky 51 clutch

[baseroom]

OK I should know this..... I was changing bar and chain on the 51. I looped the chain over the clutch and saw another small "disc" around the sprocket. I couldn't remember if I put the chain on that ..or next to it! Well did it wrong the forst time after that looped it onto it and worked fine. What is that added piece called and what is it's function?

>and I figured it out. Its the rim sprocket. Chain goes on it. Allows change frome .325 to 3/8 if needed/wanted. Every once and a while I learn something!!

Plus once it is wore you can buy just a rim drive instead of the clutch cover sprocket...

How do you know when the rim sprocket starts to wear!?

When the chain gets stuck in the wood too much...

That is the type where you have to replace the sprocket cover of the clutch,and that one is wore bad.You can see the wear on a rim drive as well
