Kohler CH440-3275 14HP 429cc Engine – 1in Shaft

Description

Spinning commercial asphalt planers and crack seal melters, the Kohler CH440-3275 horizontal shaft engine supplies continuous 14 horsepower across punishing road repair shifts. Asphalt maintenance and pavement cutting place intense continuous thermal resistance on small engines, which causes overheating and thrown connecting rods on consumer powerheads. This 429cc commercial engine features high-capacity cooling fins, a forged steel crankshaft, and an overhead valve cylinder head engineered to absorb severe mechanical resistance.

An oversized cast-iron cylinder sleeve protects internal tolerances against bore wear, keeping oil consumption low across hundreds of operating hours. Dual ball bearings anchor the 1-inch output shaft, preventing crank seal leaks caused by tight drive belts. The commercial-grade carburetor meters fuel with precision across varying load demands, preventing engine hesitation when asphalt planers cut deep into cured road surfaces.

Engineering Integrity & Operational Economy

Engineered for continuous commercial operation where equipment failure halts company revenue, this platform sets the standard for repower efficiency.

• Heavy cast iron cylinder lining and thick crankcase casting prevent thermal distortion during midsummer heat waves.
• Low oil consumption rates and 100-hour oil service intervals keep machines working in the field rather than sitting on shop lift racks.
• Pavement maintenance contractors and municipal road crews gain dependable power for high-hour machinery.

Target Machinery & Drop-In Fitment

Weighing 72.8 pounds dry with an industry-standard 4-bolt horizontal mounting base and 1-inch shaft, this motor powers asphalt crack melters, road planers, commercial wood chippers, and heavy trash pumps without frame drilling.
