🔹Product Overview

Piston Circlip Clip Retaining Ring Part No.3629516 is an important elastic locking component for cumm-ins K19, K38, K50 diesel engines, widely used on excavators, generator sets and marine heavy‑duty equipment. It is installed inside piston groove, used to limit piston pin axial movement, prevent piston pin slipping out during high‑speed reciprocating operation, and protect piston and connecting rod assembly from damage. This replacement circlip solves hidden dangers caused by original retaining ring fatigue deformation, fracture and elastic attenuation under high‑temperature and impact working conditions. Each piston circlip clip retaining ring passes dimension inspection, elastic performance test and surface defect check before delivery.
