5.8 Differential
The differential is a self-locking type, with 6 frictions faces on each side and pressure plates with ramps,
acting either for power or braking phases. The running clearance in the differential is 0.1±0.05mm.
The preload may be adjusted by tightening/untightening the preload nut (see the picture below).
External preload adjustment process:
It is important to know that the lock nut must be pushed while turning (the tool must push the lock nut
completely straight in order to be able to move the nut all the necessary travel). Note that it is made by
"clicks" (20 "clicks" per revolution). Then, it is therefore to stop on a "click" to be sure of the good lock nut
desired position.
-
It is not necessary to remove the left driveshaft.
-
Lock the right driveshaft or wheel.
-
Use the hex-head spanner of 8 mm in order to tighten/untighten the nut marked above. Then you can
adjust the preload :
-
By turning clockwise in order to decrease the preload.
-
By turning anti-clockwise in order to increase the preload.
