Very Good Pics! I have not seen lining materials on a small engine clutch vs all metal. Actually I have not seen what I felt was a bad clutch due to the shoes/hubs, bushings vs bad chain cogs on chainsaws. Your clutch looks normal IMO. Techs, What would dictate a bad clutch or cause a bad clutch shoes or drum (excessive wear, bad springs, hot spots, worn bushing)??

"If it ain't broke....." Replace the belt and "keep on chippin...." :-) Learned a long time ago, don't dig deeper unless you have to.

Your clutch is all right. I have the older Super Tomahawk which uses pulley and idler which makes the belt function as the clutch. In your case belt needs to be fairly tight so it doesn't slip. You should adjust to get about 1/2" deflection of the belt between the clutch and chipper pulley. Also, make sure you lightly oil the bushing (the brass part) where it rides on the shaft.

I also have a Tomahawk, only a underpowered 4 hp model.

My dad quickly shredded the belt on it. I finally learned that to engage the belt without killing the engine one had to gradually get the speed up by engaging it only for a second at a time. Took some getting used to. One could not start it at all with any material inside.

Anybody know part number clutch springs
