DANGER!
Risk of injury from burns! Use protective gloves.
Heat the ball bearing to a maximum of 90 °C and fit the bearing so that
it makes contact with the pinion gear.
Fit the pinion gear once the bearing has cooled down.
Fitting the sealing ring
1. To seal the gear wheel against the gear housing a sealing ring (e)
must be fitted. Before fitting the seal, use LOCTITE
®

surfaces that come into contact with each other.
2. Use a press to push the seal in until it makes contact.

2. Use tool 257412 to press the pinion gear into the gear housing until
it makes contact.

4. Apply grease sparingly to the seal. Apply LOCTITE
®
574 to the out-
er edge of the seal.
5. Use tool 257414 to push the seal in until it makes contact.
