## Customer Reviews

### ⭐⭐⭐⭐⭐ Left hand thread on clutch
*by J***. on June 6, 2025*

Working now. 025 chain saw. Seven tooth sprocket. Warning: the clutch is left hand thread. Somewhere I saw a suggestion to use an impact wrench to remove the clutch. Sounded good, but nowhere did I see that it was left hand thread. So now it is jammed on. So, I replaced the sprocket, and it works with the old clutch. The impact wrench also stripped the flywheel key. So, I lined the flywheel and shaft keyways and installed the flywheel with the stripped key. Tightened pretty good and it works. Works great now.

### ⭐⭐⭐⭐⭐ Fit my needs
*by K***N on November 20, 2024*

It fit my sthil perfectly and I've been happy since

### ⭐⭐⭐⭐ oil pump was not good quality
*by D***E on June 11, 2025*

Used the clutch and seems to work well did not use oil pump did not work with the pump gear included so used old oem pump and seems to work fine oil pump did not seem as smooth as oem and gear machining did not match
