Removing Chuck or Faceplate

The Model G0516 spindle nose mounting system uses a circular lock plate with slotted holes that are oversized at one end (keyholes). When the lock plate is rotated counterclockwise (as facing the chuck), the chuck or faceplate studs with mounting nuts can pass through the spindle nose. When the lock plate is rotated toward the back of the lathe, the oversized holes narrow to the size of the studs, allowing the mounting nuts to be tightened against the back of the lock plate, thus, securing the chuck or faceplate.

To remove a chuck or faceplate from the lathe spindle nose:

1.Disconnect the lathe/mill from the power source!

2.Move the lathe eyeshield back and out of the way of the lathe chuck so you have access.

3.Familiarize yourself with the spindle nose components shown in Figure 15.

4.Place a piece of plywood over the bed-ways to protect your hands.

ALWAYS place a piece of plywood over lathe

bed-ways before removing or installing a lathe chuck. This cov- ers the sharp corners of the bed, protecting your hands and fingers from a pinch injury.

5.Hold the chuck/faceplate with your hand or a chuck key, and using a 17mm wrench, loosen the 3 chuck mounting nuts on the back of the knurled lock plate. DO NOT back the nuts out all the way or they will scratch the metal cover when you rotate the lathe chuck.

6.Rotate the knurled lock plate toward the front of the lathe.

7.Remove the chuck/faceplate from the spin- dle nose by pulling it out (Figure 16). Note- —the tolerances are tight, so you may need to wiggle the chuck/faceplate back-and-forth, rotate it 1⁄4 of a turn, wiggle it, rotate it and continue repeating this process until the chuck comes out. Never use a pry bar or other similar tool to force the chuck/faceplate out!
