Description
Overview:
This Genuine Stihl piston pin links the piston to the connecting rod in Stihl two‐stroke engines, maintaining accurate alignment and smooth movement at the small end. Manufactured from high‐strength, hardened steel with a precision‐ground finish, it resists wear under high load and temperature. Sized 8 x 5 x 22 mm (approximately 0.31 x 0.20 x 0.87 in), it is an OEM part engineered for a precise fit and correct clearances. It helps keep engine friction low, reduces play at the piston, and supports dependable compression over time. Suited to a wide range of handheld power tools such as brushcutters, hedge trimmers, blowers, drills and Kombi engines, including Stihl SP90 and SP90T, it is an ideal replacement when overhauling a top end or addressing small‐end wear.
Key Features:
- Genuine Stihl OEM piston pin for assured fit and specification (part no. 4137 034 1500)
- Dimensions: 8 x 5 x 22 mm (approx. 0.31 x 0.20 x 0.87 in) for correct clearances
- Hardened, precision‐ground steel for excellent wear resistance and durability
- Stable running with reduced piston slap and smoother reciprocating motion
- Direct replacement design for straightforward installation with the correct circlips
- Compatible with a wide range of Stihl two‐stroke machines for simplified sourcing
- Supports reliable performance when used with clean, quality two‐stroke oil and correct service practices
Typical Applications:
Replacement during engine rebuilds, top‐end refreshes, or when addressing small‐end knock or visible pin wear. Common in routine maintenance of Stihl brushcutters, hedge trimmers, blowers, drills, Kombi engines, and pole pruners operating in landscaping, groundskeeping, agriculture, and construction site use.
Also known as:
Gudgeon pin, wrist pin, small‐end pin, piston pin (small end), piston gudgeon. These terms describe the same component that secures the piston to the connecting rod and allows the piston to pivot smoothly during engine operation.
