RING SET - PISTON STD (Doosan DWMB91H20-00830)

DWMB91H20-00830: A worn retaining ring can allow a piston to shift, leading to loss of compression or internal damage. This aftermarket replacement part references the OE maker Doosan and cross-references part number DWMB91H20-00830. The ring set secures the piston within its bore, preventing axial movement during operation. A failed retaining ring may cause the piston to contact cylinder walls, resulting in scoring or seizure. During a rebuild, inspecting the ring set for deformation or breakage is critical. The set includes standard-size rings for a piston assembly. Verify the serial number or application, then call (562) 693-7748.
