## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit
*by  on Reviewed in the United States June 10, 2026*

Perfect fit. The hardpart is getting the old one off. Then it is pretty easy to install.

### ⭐⭐⭐⭐⭐ Make sure what size crankshaft you have
*by  on Reviewed in the United States May 27, 2026*

I have a 20 hp Koehler engine on my zero turn mower this clutch assembly fit perfectly works perfectly

### ⭐⭐⭐⭐⭐ Great value clutch
*by  on Reviewed in the United States June 4, 2025*

I purchased this replacement for my Craftsman Z6000 zero-turn riding mower. Use care when removing the clutch from the box and handling during installation. The clutch components are not physically bolted together and will easily separate if handled incorrectly. This appears not to be a design flaw but how it is assembled. Make sure the new clutch electrical connector is compatible with your old clutch. Removing the clutch bolt was the most difficult step. I needed to use a cordless high torque Ingersoll Rand impact wrench to overcome the red Loctite on the clutch bolt. Next time I will use some heat on the bolt head to soften the Loctite prior to bolt removal. Once the bolt is removed, the remaining removal and installation process was straight forward. The fit was perfect. After reassembly of the engine components, the engine started normally, and the PTO clutch functioned exactly like the factory OEM clutch. The value is excellent. I could buy four of these clutches for the cost of one OEM clutch. Cheers.
