Description
Overview:
This small end bearing is a non-genuine replacement for the connecting rod small end on Stihl two-stroke engines, used in mist blowers and other handheld machines. Built as a compact needle roller bearing in durable steel with a caged design, it supports the gudgeon (wrist) pin and provides smooth rotation under high RPM, reducing friction and wear. It is suitable for Stihl SR 340 and SR 420 models and other listed machines that share the same bearing specification. The part replaces OEM reference 9512 003 2344, offering a reliable fit for routine maintenance or top-end overhauls. Made for tough outdoor use, it helps restore correct clearance at the small end, reducing play and helping protect the piston and pin during demanding operation.
Key Features:
- Non-genuine replacement part designed to replace OEM 9512 003 2344
- Needle roller construction for low friction and stable load distribution
- Hardened steel components for durability in high-temperature, high-RPM use
- Precision fit to help minimise play at the gudgeon/wrist pin
- Resistant to oil and fuel exposure common in two-stroke engines
- Straightforward to fit during piston, ring, or top-end servicing
- Helps reduce wear on the con-rod eye and pin, supporting engine longevity
- Suitable for blowers and cut-off saws used in landscaping, grounds care, and construction
Typical Applications:
Used when rebuilding or servicing the top end of Stihl two-stroke engines, especially where rattle or wear is present at the small end. Common during piston and ring replacement, gudgeon pin changes, or preventative maintenance on mist blowers and backpack blowers, as well as cut-off saws operating in dusty, high-load environments.
Also known as:
Small-end needle bearing, gudgeon pin bearing, wrist pin bearing, con-rod small end bearing, top-end needle cage, engine needle roller bearing, crankshaft end bearing (small end).
