Product Details
Product Overview
This is a high-quality DB58 Piston Ring (Part Number: 65.02503-8058) designed for use in Doosan diesel engines. As a critical component within the engine’s power cylinder group, this piston ring ensures optimal compression, oil control, and heat transfer, directly impacting engine performance and longevity.
Commonly utilized in a variety of heavy-duty applications including excavators, trucks, forklifts, bulldozers, buses, and loaders, this part is an essential replacement for maintaining the operational efficiency of your Doosan-powered equipment. While primarily associated with the DB58 engine model, it is always recommended to verify compatibility with your specific engine serial number and application.
This product is supplied by and is manufactured to OEM size specifications, offering a reliable balance of quality and value for maintenance and overhaul projects.
Key Features & Benefits
Precision Engineering: Manufactured to OEM dimensions, ensuring a proper fit within the cylinder bore and piston grooves of the DB58 engine.
Durable Material Composition: Constructed from high-grade materials to withstand extreme temperatures, pressures, and friction within the combustion chamber.
Enhanced Compression & Power: Designed to create an effective seal between the piston and cylinder wall, maximizing compression pressure for improved engine power and fuel efficiency.
Superior Oil Control: The oil ring effectively scrapes excess oil from the cylinder wall, preventing oil consumption and reducing carbon buildup in the combustion chamber.
Reduced Blow-by: Proper sealing minimizes the escape of combustion gases into the crankcase (blow-by), protecting the engine oil from contamination and maintaining engine cleanliness.
Reliable Fit Confidence: Manufactured to OEM standards, reducing the risk of premature failure associated with non-standard or inferior aftermarket parts.

FAQ
Q1: How can I confirm this piston ring fits my specific engine? A: This part is designed for the Doosan DB58 diesel engine. To confirm fitment, please check the part number on your existing piston ring (65.02503-8058) or consult your engine’s service manual for the correct ring set specifications. If your engine is a DB58 variant, this part is highly likely to be compatible.
Q2: What is the recommended installation procedure for this piston ring? A: Installation should be performed by a qualified diesel mechanic. Key steps include cleaning the piston ring grooves, checking ring end-gap in the cylinder bore, using a piston ring compressor to install the assembly, and ensuring ring gaps are staggered (not aligned) to prevent gas blow-by. Always follow the torque specifications and procedures outlined in the DB58 engine service manual.
Q3: How should I store this piston ring before installation? A: Store the piston ring in a clean, dry environment away from moisture and corrosive materials. Keep it in its original packaging to prevent scratches or deformation. Avoid exposing the ring to direct sunlight or extreme temperatures, as this could affect its material properties and dimensional stability.
