Drive, Final: Description
| 1. | PINION GEAR |
| 2. | RING GEAR |
| 3. | DIFFERENTIAL ASSEMBLY |
| 4. | TRANSMISSION CASE |
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.

| 3. | SELECTABLE SHIM |
| 4. | BEARING RETAINER |
| 5. | BEARING RACE (CUP) |
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.

| 6. | SIDE GEAR |
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.
