HOW TO CHANGE SPINDLE ADAPTERS
One of the unique features of 17" Key Chuck Drill
Presses is that they come equipped with a lower spindle
assembly having a 1 1/16" - 20 thread (A) Fig. 10, and
the Cat. No. 15-830 Drill chuck which has a threaded
mounting collar (B) Fig. 10. Various spindle adapters,
shown in Fig. 11, can also be adapted to the threaded
spindle of your 17" key chuck Drill Press. These
adapters are available as an accessory.
The spindle adapters, shown in Fig. 11, along with the
Cat. No. 15-830 Drill Chuck, shown in Fig. 10, can be
used on 17" Morse Taper Drill Presses when the lower
spindle cartridge (Part No. 402-07-301-5001 is installed
in the drill press instead of the standard #2 Morse Taper
When removing either the chuck or the spindle adapters,
we recommend the use of the Cat. No. 15838 spanner
wrench which is supplied with Key Chuck Drill Presses.
Turn the locking collar of the adapter or chuck with the
spanner wrench while keeping the spindle from turning
by either holding belt or holding the chuck with the-chuck
key in one of the pilot holes in the nose of the chuck, as
shown in Fig. 12.
When attaching adapters to the spindle, it is very
important to wipe clean both the spindle taper and taper
hole in adapter. Then place the adapter on the spindle
and tighten the locking collar (A) Fig. 12.
If in checking the spindle for accuracy, there should be a
run out, we suggest that the adapter be removed and
turned perhaps one quarter or one-half turn and
replaced. This may reduce or eliminate the run out, it
may also increase it, in which case, remove the adapter
and turn it some more on the spindle.

the right hand side of the drill press head.
The spindle return clock spring should be oiled twice a

The spindle splines should be lubricated every three
months with SAE-140 Gear Oil.
