Rear Differential Reduction Pinion Bearing Lock Ring
Mitsubishi FUSO®

The Rear Differential Reduction Pinion Bearing Lock Ring, part number MC866131, is a small but crucial component of a truck's rear differential system. This lock ring is responsible for keeping the pinion bearing in place, which is essential for maintaining proper alignment and preventing excessive wear and tear on the differential gears. Without this lock ring, the pinion bearing could shift or become loose, leading to serious damage to the differential and potentially causing a breakdown on the road. As such, it's important to ensure that this part is in good condition and properly installed during any maintenance or repair work on a truck's rear differential system.
