FAQ
Q1: Is this piston ring set compatible with the Doosan DL08 engine? The part number 65.02503-8047 is primarily designed for the DL06 engine. While the DL08 shares similar architecture, the bore size and ring profile may differ. Please verify your engine’s bore diameter and ring specifications (e.g., ring gap) against the DL06 manual. For DL08, we recommend part number 65.02503-8048 or contacting our support team for cross-reference assistance.
Q2: What is the recommended installation procedure for these rings? Installation should follow standard diesel engine rebuilding procedures: 1) Clean the piston ring grooves thoroughly. 2) Check ring end gap using a feeler gauge (refer to the service manual for gap specifications). 3) Use a piston ring compressor to install the rings onto the piston. 4) Ensure the oil ring expander is properly seated. 5) Lubricate with assembly lube before installing into the cylinder. Incorrect gap or orientation can cause ring breakage or excessive oil consumption.
Q3: How can I verify the authenticity and quality of this aftermarket part? Each set is supplied with a traceable lot number and a Certificate of Analysis (COA) upon request. We recommend checking the ring’s surface finish (should be smooth, no burrs) and verifying the part number laser-engraved on the ring against the original. Our 12-month warranty covers failures due to material or workmanship defects, providing peace of mind for fleet operators.
