Step 5:
Verify concentricity of the mandrel. Using a dial indicator, measure the runout (wobble) at the end of
the mandrel by manually traversing the table. Runout should not exceed
0.001”.
Step 1:
Remove power from unit and allow all components to reach room temperature.
Step 2:
Clean the counterbore in the idler end of the drive screw shaft that extends through the end block using
a clean cloth and acetone or alcohol. Remove all oil or foreign material that might be present.
Step 3:
Apply a light film of Loctite 638 to the counterbore.
Step 4:
Install the wedge into the end of the mandrel and insert mandrel/wedge assembly into the drive screw
shaft counterbore until the mandrel bottoms out at the shoulder. Install the long socket head cap screw and
tighten.
Step 11:
Install the brake cover making sure the wires are snug inside the brake cover including the strain relief,
and the yellow cable is placed in the wire cavity so that it is not pinched. Install and tighten two (2) socket head
cap screws.
Step 8:
Install the clutch with clamp collar onto the mandrel. Use a feeler gauge to set the clutch gap to
0.006”.
Tighten clamp collar screw and recheck gap.
Step 10:
Remove 24V supply and check that brake engages.
Step 9:
Manually traverse the table over the entire travel and check for unusual noises or dragging while the
brake is energized. If rubbing occurs, check mandrel runout. If runout is within tolerance and rubbing persists
then reset clutch gap.
Step 7:
With the brake energized, slide the magnetic housing over the mandrel. Orient the housing so that the
mounting holes align with the tapped holes in the end block. Install and tighten two (2) socket head cap screws
