RING - PISTON (Mitsubishi MB1147256)

MB1147256: A worn retaining ring can allow a piston to shift, leading to loss of compression or mechanical noise. This aftermarket replacement part cross-references Mitsubishi part number MB1147256. The retaining ring secures the piston within its bore by snapping into a groove. If the ring fails, the piston may dislodge, causing sudden stoppage or internal damage. During a rebuild, a technician often replaces the retaining ring as a precaution. Verify the serial number or application, then call (562) 693-7748. The ring is a simple, circular fastener that holds the piston in place under normal operating forces.
