Description
Overview:
This genuine Stihl piston pin is a small-end connector that links the piston to the connecting rod in two-stroke handheld engines. Precision-ground from hardened steel for wear resistance and stability, it supports smooth oscillating movement under high temperature and load. Sized 8 mm x 5 mm x 22 mm (0.31 in x 0.20 in x 0.87 in), it is designed for a precise fit in compatible Stihl cylinders and pistons. Suitable for multi-tool powerheads and handheld machines such as trimmers, blowers, hedge trimmers and saws, including KM56C and KM56RC models. Using the correct OEM pin helps maintain compression, reduces vibration from small-end play, and protects the piston and con-rod from premature wear.
Key Features:
- Genuine Stihl OEM component for assured fit and function (MPN: 4241 034 1500)
- Precision dimensions: 8 mm x 5 mm x 22 mm (0.31 in x 0.20 in x 0.87 in) for correct clearances
- Hardened steel construction for high durability and resistance to scuffing and galling
- Smooth, ground finish to minimise friction at the small end under mixed lubrication
- Stable under heat and load to help maintain consistent timing and smooth running
- Direct replacement part for straightforward fitting with compatible pistons and con-rods
- Helps restore performance, reduce rattle, and prevent collateral damage from worn pins
Typical Applications:
Used during engine rebuilds, routine overhauls, or repairs after seizure or pin wear on Stihl handheld equipment. Typical on brushcutters, trimmers, blowers, hedge trimmers, long‐reach hedge trimmers, Kombi engines, and compact chainsaws. Ideal when replacing a piston, con-rod bearing, or circlips to maintain correct small‐end geometry and reliable operation.
Also known as:
Gudgeon pin, wrist pin, piston wrist pin, small-end pin, piston connector pin. Common internal engine pin securing the piston to the connecting rod in two-stroke Stihl power tools.
