RING - PISTON SET .50MM (4) (Doosan DWMB91H20-00860)

A worn piston ring set can lead to reduced compression and increased oil consumption. The part type is a retaining ring, which secures components in position within an assembly. A plain mechanical function of this type is to hold a piston in place during operation. A concrete generic failure consequence is that a broken ring may cause scoring on cylinder walls. This aftermarket replacement part references Doosan as the OE maker and carries the cross-reference number DWMB91H20-00860. The catalog lists a spec of 50MM.
