PISTON RING SET 4 CYL 0.50 (Doosan DWD490613)

A worn piston ring set can allow combustion gases to escape past the piston, reducing compression and power output. This aftermarket replacement part references the Doosan catalog and carries the part number DWD490613. The set includes multiple rings that seal the gap between the piston and cylinder wall during operation. A common failure consequence is increased oil consumption as the rings lose their ability to scrape oil from the cylinder surface. In a four-cylinder application, this set is sized at 0.50 oversize to accommodate a rebored cylinder. The item ships at approximately 0.5 pounds. Verify the serial number or application, then call (562) 693-7748.
