Even though they came equipped on (some or most all?) Marine based M939’s, I’ll post this here for those that are considering to add such Detroit Lockers to their truck. Randomly there seems to be interest and questions about these. I have 2 which are uninstalled, so I thought I would post some pics as info about them. Hat tip to CSM Davis, all of the cool stuff I have has come from him.
The 5 ton Detroit Lockers are mechanical unit inserts which reside in the ring gear differential carrier, taking place of the spider gears and cross shaft pins.
The outer halves which are splined to each driveshaft are cogged to a cogged central ring which is fixed to the carrier via the 4 spider gear cross pin bosses as a single common piece, and held together via spring pressure forcing each half into the central ring.
