7. Verify that the chuck fits the spindle properly
by checking for any gaps between the mating
surfaces.
—if there is not a gap, proceed to Step 8.
—if there is a gap, remove the chuck, re-
clean the mating surfaces carefully, and
re-install. if the problem persists, contact
our tech support.
8.
Verify that the chuck/spindle tapers are seat-
ed firmly together by removing the chuck,
per the chuck Removal instructions, and
pay close attention to how easily the tapers
release.
—if it was necessary to bump the chuck or
use a mallet to release the tapers, then
they are seating together properly.
—if the tapers released easily with little
intervention, they are not seated together
firmly as required. remove the chuck, re-
clean the mating surfaces carefully, and
re-install. if the problem 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.

cam line is aligned with the spindle mark.

cheater pipe may be used as a last resort to
add leverage when loosening. After loosen-

the camlock to fully disengage the stud.

using a dead blow hammer or other soft
mallet, lightly tap around the outer circumfer-
ence of the chuck body to loosen it from the
spindle.
5. remove the chuck from the spindle, using
a light rocking motion to carefully slide the
studs out of the cam holes.
— if the chuck does not immediately come off,
rotate it approximately 60° and tap it again.
Make sure all the marks on the cams and
spindle are proper aligned for removal.
