Description
Overview:
The Stihl Piston Circlip 9463 650 1000 is a small but critical engine fastener used to retain the gudgeon (wrist) pin inside the piston. This genuine Stihl OEM part is made from hardened spring steel to cope with high RPM, heat and vibration in two‐stroke engines. It seats in the piston groove to stop the pin migrating sideways and damaging the cylinder. Suitable for a wide range of Stihl machines, including cut‐off saws like the TS400 and chainsaws such as the MS340, as well as brushcutters, blowers, sprayers and augers. Using the correct genuine circlip helps ensure reliable performance after top‐end rebuilds, piston changes or routine overhauls, reducing the risk of internal engine failure.
Key Features:
- Genuine Stihl OEM part for exact fit and compatibility
- Hardened spring steel construction for strength and long service life
- Securely retains the wrist pin to prevent lateral movement
- Engineered for high‐vibration, high‐RPM use in two‐stroke engines
- Consistent dimensions for dependable seating in the piston groove
- Helps protect cylinder and piston from pin walk and scoring
- Suitable for routine maintenance and full top‐end rebuilds
- Installs with basic hand tools; replace whenever a piston is changed
- Supports reliable starting, smooth running and overall engine longevity
- Stihl MPN: 9463 650 1000
Typical Applications:
Used during piston and ring replacement, wrist pin service, and complete top‐end overhauls on Stihl cut‐off saws, chainsaws, brushcutters, blowers, sprayers and earth augers. Ideal for preventative maintenance when rebuilding engines that operate in dust, heat and continuous duty, helping maintain reliability on site, in workshops, and for domestic garden machinery.
Also known as:
Piston wrist‐pin clip, gudgeon‐pin clip, internal circlip, C‐clip, retaining ring, snap ring. These terms refer to the same type of spring‐steel ring that locks into a piston groove to hold the wrist pin in place.
