🔹Product Overview

This high‑quality piston ring set 65.02503‑8236 is a critical internal‑engine component specially designed for the Doosan D2366 diesel engine, widely fitted to Doosan excavators and heavy‑duty construction equipment. Installed on engine pistons, the piston rings perform multiple core functions: sealing combustion chamber pressure, scraping excess engine oil from cylinder walls, and transferring piston heat to the cylinder liner. Made of high‑grade cast‑alloy steel with advanced surface hardening treatment, this aftermarket ring set delivers outstanding wear‑resistance, high‑temperature endurance and stable sealing performance. It is the ideal replacement part for engine rebuild, overhaul and solving problems such as oil‑burning, power loss and excessive exhaust smoke caused by worn‑out original piston rings.
