Description
Overview:
The Yanmar Pin, Spring 4.0 x 8 (MPN 22351-040008) is a small, slotted spring pin used to secure components on Yanmar single‐cylinder engines. Made from hardened spring steel with a dark protective finish, it provides a resilient, vibration‐resistant interference fit in a 4.0 mm hole. Its size is 4.0 mm diameter x 8.0 mm length (approx. 0.157 in x 0.315 in). Typical duties include locating and locking levers, shafts, and gears to prevent creep under load. This genuine Yanmar part is suited to compact plant and garden machinery engines, including the L48N5SJ1 mixer spec engine and the L100, where reliable retention of parts is essential for smooth operation and long service life.
Key Features:
- Genuine Yanmar part for assured compatibility and fit
- Hardened spring steel construction for strength and resilience under vibration
- Slotted design provides constant radial tension for a secure hold
- Compact 4.0 mm x 8.0 mm size (approx. 0.157 in x 0.315 in) for small assemblies
- Helps prevent component movement, reducing wear and noise
- Stable in harsh environments typical of site and agricultural equipment
- Simple to install with a suitable punch and correctly sized hole
- Supports routine maintenance and quick replacements with minimal downtime
Typical Applications:
Used to retain pulleys, levers, linkages, and small gears on Yanmar engines powering site mixers, generators, water pumps, plate compactors, and similar equipment. Ideal wherever a compact, vibration‐resistant fastener is needed to lock a component on a shaft or within a bore without adding bulk or weight.
