The Honda 94601-18000 Piston Pin Clip (18mm) is a genuine OEM retaining clip designed for a wide range of Honda outboard motors, generators, tillers, water pumps, lawn mowers, snow blowers, and horizontal and vertical shaft engines. As a direct Honda OEM component, this clip is manufactured to the exact dimensions required to secure the piston pin in the connecting rod and piston bore. This part is listed for an extensive range of Honda equipment including BF35, BF40, BF45, and BF50 outboard motors, GX140, GX610, GX620, and GX670 horizontal shaft engines, GXV270, GXV610, GXV620, and GXV670 vertical shaft engines, and many generators, water pumps, and tillers — verify your model and serial number against the fitment table before ordering.
Key Features
- Genuine OEM Retention — manufactured by Honda to the exact 18mm diameter specification required to lock the piston pin securely in place, preventing lateral movement within the piston bore
- Broad Cross-Platform Fitment — listed for Honda outboard motors, horizontal and vertical shaft engines, generators, water pumps, tillers, commercial mowers, and snow blowers across multiple product families; confirm your model in the fitment table
- Serial Number Verification Recommended — Honda supersedes piston components at serial breaks; always check your unit's serial number against the fitment table to confirm part number 94601-18000 is correct for your serial range
- Engine Integrity at Stake — a failed or missing piston pin clip allows the pin to walk laterally and score the cylinder bore, leading to rapid loss of compression and engine damage
The piston pin clip is a small circlip or snap ring that seats in a machined groove at each end of the piston pin bore, locking the wrist pin in position so it cannot shift sideways as the piston travels up and down in the cylinder. It is a critical internal engine component — without it, the piston pin is free to migrate toward the cylinder wall, gouging the bore and destroying the piston and connecting rod. When performing any top-end engine service that requires piston removal, replacing this clip with a fresh genuine OEM piece is standard practice, since the clip is deformed during removal and must never be reused.
