Adjusting the differential.

Adjusting the differential.

Adjust the first of the sun gears : Fig. I and II.

Prepare the assembly shown in figure 1.

Set extension B 8.0110 H H, fitted with dial indicator D 8.1504 and a 35 mm spacer, on the housing, with the dial indicator plunger against one of the teeth on the sun gear.

Adjust the dial indicator to zero.

Without moving the extension, rest the assembly on the end of the sun gear at (a).

Repeat this operation on several different teeth. The minimum end float should be approximately 0.10 mm.

If it is not, fit an adjusting washer of the thickness necessary to obtain the required end float.

Fit : Fig. IV

• - the spindle dowel pins (2).

Fit the second sun gear (3) and the second adjusting washer (4) (with its groove against the wheel).

Adjust the second sun gear : Fig. III and IV.

Place the extension fitted with the dial indicator and a 20 mm adapter against the differential flange (1).

Set the dial indicator on zero.

Place the extension against the adjusting washer (4) with its plunger on the differential housing.

Take this reading at several different point.

The minimum difference should be approximately 0.10 mm.

If it is not, fit a washer of the required thickness to obtain this difference.

Fit, to the housing : Fig. V and VI.

• - the flange (1),
• - the crown wheel (with groove (b) on the same side as the bolt heads).

Tighten the bolts to 9 m.daN (90 Nm, 66 lbf ft) (faces and threads oiled).

Ensure that the assembly turns freely, without any tight points.
