Differential Assembly: Description and Operation

A new final drive unit designated 14HU is fitted to the XK8 and is externally similar to the current 95MY sedan unit. The internal design features a stiffened pinion for improved refinement and a new main gearset with reduced offset, increased contact ratio and reduced sliding for greater efficiency. This unit is oil filled-for-life and does not have a drain plug fitted. The only serviceable components are the output bearing and seal and the pinion oil seal. The pinion is on the center line of the vehicle which improves the driveline alignment. The pinion oil seal is a cassette unit. Dedicated tools are required to remove the cassette unit.

The weight of the final drive unit is 46 kg (101 lbs).

Oil capacity is 1.76 litres (0.46 US galls).
