Maintenance

To Replace Antifriction Bearings

1. Remove bolts holding end caps to housings.

2. Remove bolts holding bearing housings to yoke.

3. Remove bearing housings.

4. Remove the bearing with a puller. See Figure 6.

5. Check shaft and housing diameter for proper size

with micrometer.

6. Heat the new bearing in an oven (200°F). While

it is hot, slide the bearing onto shaft – make

certain that the inner race makes a firm even

contact with shaft shoulder. Do not subject

bearing to impact.

7. Let bearing cool - pack bearing caps with the

proper grease.

8. Reassemble end caps and housings.

The amount of grease to be used when repacking a
