Determine the thickness of the spacer washer without the pinion
Install the external races (2, 10) of the tapered roller bearings in the differential case (1) . Measure without the spacer washer (8) and the spacer bushing (9).
1 | Install taper roller bearings (3, 11). |
2 | Measure and record the "A" dimension between the outer faces of taper roller bearings (3, 11). |
The measurement requires a caliper holder (arrow). Use the supporting device together with a thrust base (13). |
3 | Measure and record dimension "B" by adding the "C" and "D" dimensions. |
The “D” level is the spacer bushing height (9). The “C” level is the height of the tapered roller bearing (11). |
4 | To determine dimension "E", subtract from dimension "A" (step 2) the sum of dimension "B" (step 3) and dimension "F". |
The “F” level is the height of the tapered roller bearing (3). |
The spacer washer thickness (8) is determined by the level “E” amount less the amount indicated for the pre-load of the pinion's tapered roller bearings. |

Determine the thickness of the spacer washer with the pinion
Only when the tapered roller bearing (11) is mounted on the pinion (12).
5 | Install the pinion (12) with the tapered roller bearing (11). |
6 | Install the retaining device on the differential case (1) and tighten the spindle (arrow) against the pinion (12). |
B35.31-0027-01
7 | Measure and record the depth (arrow A) between the differential case face (1) and the inner face of the tapered roller bearing (11). |
Use a depth caliper with an appropriate size so it can be supported on the differential housing face (1). If no depth caliper with an appropriate size is available, use two parallel supports for the measurement. |
8 | Remove the pinion (12) together with the tapered roller bearing (11) and install the tapered roller bearing (3). |
9 | Measure and record the distance (arrow B) between the differential case (1) and the outer face of the tapered roller bearings (3). |
Use a depth caliper with an appropriate size so it can be supported on the differential housing face (1). If no depth caliper with an appropriate size is available, use two parallel supports for the measurement. |
10 | Subtract from the measure found in step 7 the measure found in step 9. |
11 | In order to determine the the dimension “E”, subtract from the value found out in step 10 the sum of “D” plus “F” dimensions. |
Dimension "D" is the height of the spacer sleeve (9). Dimension "F" is the height of the tapered roller bearing (3). |
The spacer washer thickness (8) is determined by the level “E” amount less the amount indicated for the pre-load of the pinion's tapered roller bearings. |
