Word of caution when using this tool. If the stationary half of your primary clutch sheeve is stuck on the crankshaft do not overtorque this puller or risk damaging the tool or worse yet the crankshaft. Apply heat or boiling water to the clutch to at the base of the tapered to help break the bond
The very first time I used this puller the end bent so horribly that I could barely remove it from the clutch. And on top of that it wouldn't break the clutch free. I would expect this tool to be made out of high grade tool steel that wouldn't deform with such little force. This seems to be plated mild steel. If you want a puller that will do the job and not ruin your clutch, look elsewhere.
The end of the puller bent the first time I used it and it never did pop the clutch off. This was a new sled with 300 miles so the couch was not stuck. I ended up using the water method and it popped off easy. Would not recommend this puller.
