Description
Overview:
The Kohler Piston Pin Retainer (OEM No. 24 018 01-S) is a small but vital engine component that locks the piston pin (gudgeon pin/wrist pin) securely in the piston to prevent movement during operation. Made from hardened spring steel for strength and elasticity, it maintains a reliable grip under heat, vibration and oil exposure. This genuine Kohler part ensures the correct fit and retention force required by the manufacturer. Suitable for a wide range of Kohler twin-cylinder petrol engines used in construction and garden machinery, including CH18 and CV25, it supports smooth running and helps protect cylinders and pistons from avoidable damage. Ideal for engine rebuilds, overhauls and preventative maintenance where OEM accuracy and durability are essential.
Key Features:
- Genuine Kohler part for assured compatibility and performance (OEM 24 018 01-S)
- Hardened spring steel construction for wear resistance and long service life
- Precise OE dimensions to seat correctly in the piston groove
- Helps prevent wrist pin movement and associated piston/cylinder damage
- Stable retention under heat, oil and vibration typical of small engines
- Straightforward push-fit with standard circlip pliers, aiding fast maintenance
- Suitable for routine top-end rebuilds and repairs across many Kohler engines
- Supports reliable starting, smooth running and sustained engine efficiency
- Matches Kohler specifications for correct tension and sealing
- Trusted brand quality for workshop and DIY use
Typical Applications:
Used during piston and ring replacement, top-end overhauls, and routine maintenance on Kohler-powered ride-on mowers, garden tractors, zero-turns, chippers, log splitters, generators and compact construction equipment. It keeps the piston pin correctly positioned to reduce wear, protect the cylinder bore, and maintain consistent engine performance.
