Limited Slip Differential (818C5 engine)
Description
t
f 1 t
1. Function
Operation of the limited slip differential is dependent upon the eight pinion gears that are in mesh with the two side
gears. They transfer the driving power to the driving axles as well as permjt the outside wheel to turn more times than
the inside wheel when the vehicle goes around a turn. All gears are helically cut so that this differential action is limited
by the friction created between each gear and differential carrier when either wheel slips.
2. Construction
The unit consists of the two side gears, four short pinion gears, four long pinion gears, two thrust washers, a center
washer, and a carrier that houses the gears and washers. One shon and one long pinion gear are in mesh with each
other and are allowed to walk around the side oears.

The differential carrier and gears rotate together as a unit when both wheels rotates at the same speed. Turning
effon from the final driven gears are directly transmitted to both wheets.
