Detailed Description
The Holzfforma G660 powerhead is engineered to replicate the fit and function of popular high-displacement chainsaws. It is a replacement power unit designed around a 54mm cylinder bore to match MS660 / 066 models. With a 5.2 kW output from a 92cc displacement, it provides the torque necessary for large-diameter cutting and continuous workload. The package focuses on the powerhead itself — you receive the starter assembly, crankcase, and sprocket cover intact, leaving the guide bar and chain selection up to you.
Installation is straightforward for anyone familiar with chainsaw mechanics: mount the powerhead onto your existing housing, fit the sprocket and chain that match the specified 3/8″ .063″ pitch, and secure the luxury wrap around handle. This makes it an excellent option if you need a replacement power head MS660 purchase or want a 54mm bore powerhead for MS660 with wrap around handle.
