Kohler 1901902-s Coated Tappet Engine Part

Product Description

The KOHLER 1901902-s is a coated tappet designed for use in small engine valve train assemblies. Tappets, also called valve lifters, ride against the camshaft lobes and transfer motion to the pushrods or valves, controlling intake and exhaust timing. The coated surface on this tappet reduces friction and wear against the cam lobe, helping maintain consistent valve lift and engine performance over time. This part is a direct OEM-style replacement used by small engine technicians and power equipment service professionals during valve train rebuilds or wear-related repairs.

This tappet is suited for KOHLER small engines commonly found in outdoor power equipment such as generators, lawn tractors, zero-turn mowers, pressure washers, and other engine-driven tools. The coated finish makes it appropriate for applications where extended service intervals or higher cam lobe contact stress is a concern. Installation is typically performed during a top-end or full engine rebuild when tappet wear, pitting, or spalling is observed during inspection.

Key Features

• Coated contact surface reduces friction and extends service life against camshaft lobes
• OEM KOHLER part number ensures correct geometry and fit within the engine block
• Designed for valve train assemblies in KOHLER small engines used in power equipment
• Direct replacement for worn or damaged tappets found during engine inspection or rebuild

Compatibility

Designed as an OEM-style replacement tappet for KOHLER small engines used in power equipment and generator applications. Consult the KOHLER parts lookup tool or engine service manual using the engine model and spec number to confirm fitment before ordering.

Installation Notes

Tappet replacement is performed by qualified small engine technicians as part of a valve train inspection or engine rebuild. Drain oil and disconnect the spark plug wire before disassembly. Tappets must be installed in their original bore positions if reused; when installing new tappets, coat the contact surface with clean engine oil before assembly. Follow the applicable KOHLER engine service manual for valve clearance inspection and any required break-in procedure after reassembly.
