6.7 Cleaning The Chuck
Over time, the inner mechanism of the Chuck can become dirty, causing it to operate poorly.
Cleaning the inner mechanism can help the Chuck work smoothly again.
1. Remove the Chuck
Remove the Chuck from the Chuck Shaft. Refer to section 6.6.
2. Remove the Chuck Jaws
Remove the Chuck jaws, noting the location of each jaw so it can be reinstalled in its original
location.
3. Clean the Chuck
Clean the Chuck with brake cleaner, spraying the inner mechanism as much as possible. If the
operator has access to a parts washer it is recommended the Chuck be cleaned in this manner
4. Lubricate the Chuck
With the Chuck clean, lightly lubricate the inside with a quality spray lubricant.
5. Re-install the Chuck Jaws
Re-install the Chuck jaws, ensuring they are installed in the same location and on the same
rotation of the Chuck key.
6. Re-install the Chuck
Re-install the Chuck. Tighten the Chuck mounting screws then give each screw another
quarter turn.
6.8 Y-Axis Backlash Adjustment
The Y-Axis should have no backlash. The Y-Axis Drive gear should rotate freely on the axis,
needed.
1. Loosen the Y-Axis Motor
2. Reposition the Y-Axis Motor
Reposition the Y-Axis Motor so that the Y-Axis Drive Gear meshes against the Nylon gear
without any backlash. Adjust it to the tightest point in order to avoid binding when the Y-Axis
rotates.
