Drill Chuck Removal

The Model G0463 may have shipped with the drill chuck installed in the spindle. If this is the case, go ahead and remove the chuck and arbor at this time.

Tools Needed:

Qty

Brass Hammer

1

Pin Spanner

1

Wrench 17/19mm

1

To remove the chuck and arbor from the spindle:

1.UNPLUG THE MILL/DRILL!

2.Remove the plastic cap that covers the drawbar.

3.Lock the quill in place with the quill lock.

4.Insert the pin spanner into the two holes at the bottom of the spindle. This will keep the spindle from turning, and allow you to loosen the drawbar (see Figure 8).

5.Using the 17mm wrench, loosen the drawbar but DO NOT remove it.

NOTICE

DO NOT completely unscrew the drawbar before striking it with the hammer. You will damage the threads on the drawbar and the arbor.

6.Tap the top of the drawbar with the hammer. This will unseat the taper of the arbor and the spindle (see Figure 9).

7.Hold one hand under the chuck and finish loosening the drawbar by hand until it falls out of the spindle.

Note: The chuck is attached to the arbor using a JT6 taper. This attachment is consid- ered to be semi-permanent. There should be no need to remove the chuck from the arbor. Inspect the chuck from time to time to make sure it is still tight on the arbor. If it is loose, use an dead-blow or other soft headed ham- mer to re-seat the taper.
