Chuck Removal - Grizzly G0750GV Owner's Manual

7. Verify that chuck fits spindle properly by
checking for any gaps between mating
surfaces.
— If there is not a gap, proceed to Step 8.
— If there is a gap, remove chuck, re-clean
mating surfaces carefully, and re-install.
If problem persists, contact our Tech
Support.
8.
Verify that chuck/spindle tapers are seat-
ed firmly together by removing chuck, per
Chuck Removal instructions on following
page, and pay close attention to how easily
tapers release.
— If it was necessary to bump chuck or use
a mallet to release tapers, then they are
seating together properly.
— If tapers released easily with little interven-
tion, they are not seated together firmly as
required. Remove chuck, re-clean mating
surfaces carefully, and re-install. If prob-
lem persists, contact our Tech Support.
Registration Marks
Lightly stamp registration marks across the mating
seams of chuck components. These marks will
help you re-install the chuck in the same position
after removal, which ensures consistent chuck
balance and turning results, and allows the
same camlocks and studs to operate together for
consistent locking and unlocking.

Chuck Removal

To remove chuck:
1.
DISCONNECT MACHINE FROM POWER!
2.
Use appropriate lifting, support, or protective
device to protect ways and support chuck
(refer to Chuck Safety & Support Devices
section for more details).
3.
Loosen camlocks by turning key counter-
clockwise until each cam line is aligned with
its corresponding spindle mark, as shown
below.
Cam line and spindle mark aligned
Figure 29. Camlock is fully loosened when the
cam line is aligned with the spindle mark.
Tip: Camlocks can become very tight. A
cheater pipe may be used as a last resort to
add leverage when loosening. After loosen-
ing, you may need to wiggle the chuck key in
the camlock to fully disengage the stud.
4.
Using dead blow hammer or other soft mal-
let, lightly tap around outer circumference of
chuck body to loosen it from spindle.
5. Remove chuck from spindle, using light rock-
ing motion to carefully slide studs out of cam
holes.
— If chuck does not immediately come off,
rotate it approximately 60° and tap it
again. Make sure all marks on cams and
spindle are properly aligned for removal.
