COUPLER A (Mitsubishi MB2M2689)

A worn coupler can disrupt the transfer of rotational force between connected shafts. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB2M2689. The coupler type generally serves to join two rotating components while accommodating minor misalignment. A plain mechanical function is to transmit torque from one shaft to another without slippage. A concrete generic failure consequence is that a degraded coupler may cause vibration or noise during operation. Keeping a coupler in sound condition helps maintain consistent power transmission in rotating assemblies. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.075 pounds.
