YOKE ASSEMBLY
1. Heat the tapered bearings, 1, and both needle
bearing races, 2, in a bearing oven to 80 - 85°C
(170 - 180°F). Position the eccentric shaft in a
holding tool with the drive end down.
CAUTION
The bearing and race are very hot!
2. Drop the heated outer bearing, 1, onto the shaft
with the tapered end up. Ensure that the bearing
slides down the shaft evenly and completely
against the shoulder. Allow the bearing to cool
and shrink before moving the shaft.
3. Rotate the shaft in the holding tool so that the
drive end is pointing up. Drop the heated race, 2,
(larger) onto the shaft with the flanged end down.
Ensure that the race slides down the shaft evenly
and completely against the shoulder. Allow the
race to cool and shrink before moving the shaft.
