PIN-SPRING (Mitsubishi MB0455106)

A worn retaining ring can allow a pin to shift, leading to mechanical misalignment or detachment. This aftermarket replacement part is cross-referenced to Mitsubishi part number MB0455106. The pin-spring assembly functions as a retaining ring, securing a pin within a bore or housing. Its plain mechanical role is to hold the pin in position under normal operating loads. If the retaining ring fails, the pin may walk out, causing sudden loss of connection between linked components. During a service check, a technician might find a loose pin that indicates a degraded retaining ring. Verify the serial number or application, then call (562) 693-7748.
