Kohler CH730-3201 23.5HP 747cc V-Twin Engine – 1-7/16in Shaft, Electric Start

Description

During continuous 8-hour timber processing shifts, the Kohler CH730-3201 horizontal shaft engine delivers continuous 23.5 horsepower across punishing sawmill cuts. Sawing through massive hardwood logs places intense continuous load resistance on engine drive shafts, which causes shaft deflection and bearing failure on smaller engines. This 747cc commercial V-twin engine features an extra heavy-duty 1-7/16-inch output shaft and a forged steel crankshaft engineered to absorb severe torsional shock loading without bending.

Dual cylinder cast-iron sleeves protect internal tolerances against bore wear, keeping oil consumption low across hundreds of milling hours. The 1-7/16-inch horizontal shaft handles large industrial drive pulleys and multi-groove belt systems without crankshaft deflection. Full-pressure lubrication circulates filtered motor oil directly to high-load rod bearings, ensuring uninterrupted fluid barrier protection during continuous full-throttle cutting passes through knotty frozen timber.
