3. Measure how far under the standard thickness [20 mm (0.79
in)] the side bearings are.
It will require tools shown below.

4. Place the outer race of the opposite side bearing to the mea-
sured.
5. Place a weight block on the outer race, and a master gauge on
the block.
Tool number:
q
AST32501000

BKV38101900
6. Adjust dial indicator scale to zero.
7. Carefully slide master gauge and weight block out from under
dial indicator.
8. Lubricate side bearing and place the bearing outer race and
inner cone to be measured on the opposite side outer race.
If the bearing assembly is placed on the base plate, the bear-
ing width cannot be accurately determined due to its cage
being in contact with the base plate.
9. Place weight block (ST32501000) on side bearing.
10. Slide dial indicator on weight block.
11. Turn weight block a few times to ensure that bearing is prop-
erly seated.
12. Read dial indicator.
INormal indication:
0.10 - 0.30 mm (0.0039 - 0.0118 in)
IIf the needle fluctuates erratically then bearing is either dirty or
defective and should be cleaned or replaced.
