BUSHING - PISTON PIN (Mitsubishi MB1200840)

A worn piston pin bushing can lead to excessive clearance and noise in the connecting rod assembly. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1200840. The bushing serves as a bearing surface between the piston pin and the connecting rod. Its plain mechanical function is to reduce friction during the piston's reciprocating motion. A common failure consequence is increased wear on the piston pin bore, which may cause knocking sounds. Keeping the bushing in sound condition helps maintain proper alignment within the assembly. Verify the serial number or application, then call (562) 693-7748.
