Differential Adjustment

Differential Adjustment

• Using a centesimal dial gauge and tool No. 1.820.085.000, measure the distance "P" between the resting plane of the seal cover and the outer ring of the roller bearing.

Given that the fixed number 0.12 corresponds to the negative allowance prescribed for the settling and pre-loading of the bearings for the differential casing, determine value "S" of the thickness of the shim rings by applying the following formula:

S = P - H + 0.12

NOTE: After the exact thickness of the shim ring has been obtained select a ring from among those supplied as spare parts which is as near as possible to this value.

• Using a centesimal dial gauge and tool No. 1.820.085.000, measure height "H" of the seal cover.

If the value obtained in this way does not correspond to one of the shim rings available, or to the sum of two rings, install the next thickness up.

NOTE: Thicknesses "S" of the shim rings supplied as spare parts range from 1.70 to 2.60 mm increasing in steps of 0.05 mm.
