Description
Overview:
The Piston Circlip 19 mm for Yanmar L40 and L48 engines is a small but critical component that locks the piston pin (gudgeon pin) securely in place. Made from durable, hardened steel for strength and resilience, it prevents axial movement of the pin and protects the cylinder and piston from costly damage. This non-genuine part is manufactured to consistent dimensions for dependable seating in the piston groove. It matches the 19 mm pin size (0.75 in / 3/4 in) used on these compact air‐cooled diesel engines found in construction and garden machinery. Compatible with OEM reference 22252-000190, it offers a reliable, cost-effective replacement for maintenance or rebuilds where a fresh circlip is essential to engine integrity and smooth operation.
Key Features:
- 19 mm fit for piston pin/gudgeon pin applications (0.75 in / 3/4 in)
- Non-genuine part offering practical value while remaining compatible with OEM No. 22252-000190
- Hardened steel construction resists fatigue and deformation under load
- Precision-formed profile ensures positive retention in the piston groove
- Clean ends and accurate tolerances for straightforward fitting with standard circlip pliers
- Stable performance in demanding engine environments and continuous running
- Helps maintain piston alignment and reduces risk of pin walk and bore damage
- Suitable for routine overhauls, preventative maintenance, and repairs on small diesel plant
Typical Applications:
Used during piston and connecting rod service on Yanmar single-cylinder diesel engines in light plant and garden machinery. Typical equipment includes plate compactors, generators, water pumps, small mixers, and site tools where L-Series engines are common. Ideal when replacing pistons, piston pins, or after removing an old clip during inspection.
Also known as:
Snap ring, retaining ring, piston pin clip, wrist pin clip, gudgeon pin clip, C-clip, piston retaining clip. These terms refer to the same style of ring that locks the piston pin within the piston to prevent side movement during operation.
