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.
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,
1
rotate it
of a turn, wiggle it, rotate it and
4
continue repeating this process until the
chuck comes out. Never use a pry bar or
other similar tool to force the chuck/faceplate
out!
