PISTON RING SET 4 CYL 0.50 (Doosan DWKM4942155)

DWKM4942155: A worn piston ring set can allow combustion gases to escape past the piston, reducing compression and causing power loss. This aftermarket replacement part references the Doosan catalog number DWKM4942155. The set includes rings for a four-cylinder application with a 0.50 oversize specification. Piston rings seal the gap between the piston and cylinder wall during operation. A common failure consequence is increased oil consumption as rings lose their sealing ability. The part type generally functions to control oil distribution on the cylinder wall. Verify the serial number or application, then call (562) 693-7748.
