drill chuck arbor
your machine includes an r-8 drill chuck arbor
and Mt#3 drill chuck. Before use, the drill chuck
must be installed onto the arbor. this drill chuck
installation is intended to be semi-permanent.
tip: For a permanent installation, chill the arbor
in the freezer for 15 minutes before performing the
following procedure. The taper will expand as it
returns to room temperature, permanently locking
the chuck.
to install the drill chuck onto the arbor:
1.
Clean the grease off the drill chuck and all
taper mating surfaces. pay particular atten-
tion to the Mt#3 bore in the drill chuck—it
must be free from all grease, oil, and debris.
2.
retract the drill chuck jaws fully by turning the
body of the drill chuck counterclockwise.
3.
insert the arbor into the drill chuck. tap the
arbor lightly with a brass or other soft-headed
hammer, as shown in figure 38 to get a
good fit.
note: While it may not seem like there is
anything keeping the drill chuck in place, the
MT#3 taper fit provides a strong bond and will
hold the drill chuck tightly.
