Kohler 2401801-s Piston Pin Retainer

Product Description

The KOHLER 2401801-s is a piston pin retainer designed to secure the piston pin within the piston assembly of a small engine. The retainer holds the wrist pin in position, preventing lateral movement that would damage the cylinder bore, connecting rod, or piston skirt. This is a genuine Kohler replacement part used in engine rebuild and piston service work. Licensed small engine technicians and power equipment mechanics install this component during piston overhaul procedures.

This retainer is applicable to Kohler small engine platforms commonly found in lawn and garden equipment, including riding mowers, zero-turn mowers, and outdoor power machinery. It is sourced as an OEM-equivalent replacement for piston pin service on compatible Kohler engine assemblies. Technicians performing top-end engine rebuilds will encounter this part when replacing worn or damaged piston pin retention hardware.

Installation Notes

Installation is performed by a qualified small engine technician during piston or top-end engine service. The engine must be fully shut down and all fuel and ignition sources isolated before disassembly begins. Use appropriate snap ring pliers or retainer installation tools to seat the retainer properly in its groove without distorting the clip. Consult the applicable Kohler engine service manual for the correct installation orientation and inspection procedures before reassembly.
