1 | Install the tapered roller bearings (3) and (11).. . |
2 | Measure and record dimension "A" between the outer faces of tapered roller bearings (3) and (11). |
3 | Measure and record dimension "B" by adding the "C" and "D" dimensions. |
4 | To determine dimension "E", subtract from dimension "A" (step 2) the sum of dimensions "B" (step 3) and "F". |
Determining the thickness of the pinion spacer washer is possible only after completing the adjustment of the basic pinion depth against the crown.
Install the outer races (2) and (10) of the bearings. Measure without the spacer washer (8) and the sleeve (9).
Measuring requires a thrust base (13) to support the caliper ruler (arrow). Use the holding device together with a thrust base (13).
Dimension "C" is the height of the tapered roller bearing (11), and dimension "D" is the height of the spacer sleeve (9).
Dimension "F" is the height of the tapered roller bearing (3).
The spacer washer (8) thickness is determined by the value of dimension "E" less the value prescribed for the pinion bearings preload.
Determine the thickness of the spacer washer without the pinion |
B35.31-0026-11
Only when the tapered roller bearing (11) is mounted on the pinion (12).
Determining the thickness of the pinion spacer washer is possible only after completing the adjustment of the basic pinion depth against the crown.
Determine the thickness of the spacer washer with the pinion |
1 | Install the pinion (12) with the tapered roller bearing (11) at the tapered group box (1). |
2 | Install the fastening device on the tapered group housing (1) and tighten the spindle (arrow) against the pinion (12). |
B35.31-0027-01
Dimension "D" is the height of the spacer sleeve (9). Dimension "F" is the height of the tapered roller bearing (3).
The spacer washer (8) thickness is determined by the value of dimension "E" less the value prescribed for the pinion bearings preload.
3 | Measure and record the distance between the face (arrow A) of the tapered group housing (1) and the inner face of the tapered roller bearing (11). |
4 | Remove the supporting device , the pinion (12), together with the tapered roller bearing (11) and install the tapered roller bearing (3). |
5 | Measure and record the distance between the face (arrow B) of the tapered group housing (1) and the outer face of the tapered roller bearings (3). |
6 | Subtract the measurement found in step 5 from the measurement found in step 3. |
7 | To determine dimension "E", subtract the sum of dimensions "D" and "F" from the value found in step 6. |
