KM Manual Clamping Unit • Disassembly Procedures (continued)
6. Clean locking balls, torque screw, lockrod, and bump-off pin of all
grease and inspect for wear, burrs, or obvious damage. If rebuilding the
unit with a repair parts package, we recommend using all new components
contained in the kit. If you are not using the repair package, but are retiming
or adjusting the unit, inspect the external threads on the torque screw and
lockrod, the locking ball contact surfaces on the lockrod, and the mating
surfaces between the lockrod and bump-off pin. Discard any components
of questionable condition and replace with new ones. Note the condition
of the raised taper key on the lockrod as you will need this later.

7. Inspect inside the KM taper for damage and/or contamination. Clean the taper
and canister with solvent. Allow the unit to dry before reassembling. Inspect the
torque screw threads in the body for damage.
8. If the unit is equipped for through-coolant capability, you may want to verify
that the coolant passages are clear. Clean if required.
