Description
Overview:
The Retainer, Piston Pin is a small but critical internal engine component that holds the piston pin securely in the piston, preventing lateral movement and wear. This genuine Kohler part is manufactured to OEM tolerances for a precise, repeatable fit in compatible engines such as the CH1000 and CV940. Made from durable, heat‐resistant steel, it withstands continuous vibration, temperature cycling, and oil exposure inside the crankcase. By keeping the piston pin correctly seated, it helps maintain piston alignment, reduces the risk of scoring in the cylinder, and supports consistent engine performance. It is intended for construction and garden machinery powered by specified Kohler engines, including ride‐on mowers, compact equipment, and commercial turf machines where reliability and long service life are important.
Key Features:
- Genuine Kohler part for OEM No. 62 018 04-S, ensuring correct fit and function
- Precision-engineered to locate securely in the piston groove and retain the piston pin
- Durable steel construction for resistance to heat, oil, and vibration
- Helps prevent piston pin migration that can cause cylinder and piston damage
- Consistent dimensions for easy installation without modification
- Supports stable compression and smooth engine operation
- Direct replacement for worn or lost retainers during engine rebuilds or repairs
- Reduces downtime by restoring the assembly to factory specification
- Suitable for professional workshops and DIY maintenance on supported Kohler engines
Typical Applications:
Used during piston and cylinder service, top‐end rebuilds, or when replacing pistons and pins in Kohler‐powered machinery. Common on ride‐on mowers, commercial turf equipment, compact construction machines, generators, and similar equipment that uses the listed Kohler engines. Ideal for preventative maintenance to avoid internal damage from a drifting piston pin.
