2. Slide the lock plate away from the lock nut.
3. Rotate the lock nut using both hands until it is snug. This is the zero reference
point.
4. Mark or note the angular position of the lock nut.
5. Use the offset spanner wrench in the tool kit to rotate the lock nut approximately
1.25ā1.5 additional turns.
6. Reapply the lock plate. If necessary, additionally tighten the lock nut until a slot
in the lock plate is aligned with the retaining screw holes.
7. Reinstall the retaining screws.
3.4 ID-mount bearing support
The ID-mount bearing support assembly can be placed inside of the workpiece at any
position along the bar.
1. Clean the bore with solvent to remove grease, oil, and dirt.
2. Examine the bar for nicks or cuts. Dress the bar smooth if necessary. A bar with
nicks or gouges can severely damage mating parts, including the tool carrier
assembly and RDU. Clean the bar with solvent to remove dirt and chips.
3. Measure the diameter of the bore into which the bearing is to fit.
