DIFFERENTIAL
DESCRIPTION
The T850 differential is a conventional open
design. It consists of a ring gear and a two-piece dif-
ferential case. The differential case contains the pin-
ion and side gears, three floating pinion shafts, and a
pinion shaft retaining ring (Fig. 96). The differential
case is supported in the transaxle by tapered roller
bearings.
OPERATION
The differential assembly is driven by the interme-
diate shaft via the ring gear. The ring gear drives the
differential case, and the case drives the halfshafts
through the differential gears. The differential pinion
and side gears are supported in the case by pinion
shafts and thrust washers. Differential pinion and
side gears make it possible for front wheels to rotate
at different speeds while cornering.
