2. Rotate the connecting flange to check the runout.
Note: Flange runout value (surface on the inside of the bolt holes): 0.15 mm.
3. Install the dial indicator probe onto the inside of the flange (socket).
4. Rotate the connecting flange to check the runout.
Note: Flange runout value (socket for flange lock nut): 0.2 mm.
5. If the obtained values do not correspond to the norm, perform the following:
- Check the flange runout by rotating the flange 90°. Select the installation position with the minimum runout.
- Replace the connecting flange with a new one if the zone runout is still not within the norm.
- Adjust or replace the pinion shaft bearings with new ones if the runout value is not within the norm even after replacing the flange.
Caution: Each time the connecting flange is adjusted or replaced, the composite spacer must be replaced with a new one.
