Kohler CH620-3158 19HP 674cc V-Twin Engine – 1in Shaft, Electric Start

Description

During continuous 8-hour service truck shifts, the Kohler CH620-3158 horizontal engine maintains rock-steady shaft output on heavy two-stage air compressor skids. Commercial service trucks put severe continuous resistance on engine drive shafts when running pneumatic impact wrenches and tire inflators. This 674cc 19HP Command PRO engine features an overhead valve cylinder layout and a forged steel crankshaft that withstand high radial belt loads and sudden pressure unloader cycles.

An oversized cast-iron cylinder sleeve protects bore roundness against road grime, keeping ring tension tight over hundreds of compressor hours. Full-pressure lubrication circulates filtered motor oil directly to high-load rod bearings, ensuring uninterrupted fluid barrier protection during continuous full-throttle operation. The 1-inch horizontal shaft handles direct compressor couplings and heavy multi-groove drive pulleys without crankshaft deflection.
