Drive, Final: Description
The 62TE's final drive system is driven by the underdrive compounder's output hub/ carrier assembly. The final drive consists of the remote pinion gear, a ring gear, and a conventional differential assembly. A 23-tooth pinion gear in mesh with a 79-tooth ring gear results in a final drive ratio of 3.43:1.

The 23-tooth remote pinion is a helical gear driven by the output hub/carrier assembly. It is supported by a bearing retainer and two tapered roller bearings, which centers the gear on its axis. The bearing preload is adjusted with a selectable shim, located between the outer bearing race and the bearing retainer. The preload measurement and adjustment must be made with the differential assembly removed.

The differential assembly is supported by two tapered roller bearings and contained in a structural "clamshell" housing. It is a conventional, open type (non-locking) and is contained in a two-piece, closed case. Differential bearing preload is set with a selectable shim, with the pinion gear removed. The preload for the internal/spider gears is set with shims, as well. The 224 mm (8.82 in.) ring gear is bolted to the differential case.
