I have a Rockwell/Delta 17-600 variable speed drill press with a
variable speed pulley problem. According to delta it is from the
early 1960's and the part is no longer available. The problem is the
variable width pulley mounted on the motor has a nasty wobble which
results in big vibrations. This is the older style, without a spring.
The fixed part of the pulley (where the wobble is) is mounted to a
splined shaft that mounts on the motor shaft. The pulley is pinned on
to the splined shaft, and evidently it wasn't true when it was pinned;
hence the wobble (axial play). Does anybody know where I might get a
good used part, or has anybody had any luck with machining off some of
the splines and installing a bushing??? I have tried Ace tool repair
and Joe at Plaza machines, with no luck.
Thanks in advance for any help or advice.
Isn't the 17-600 the old "stand-by" 16" floor model that as far as I know is
still sold today? Sure I saw it for sale at WWW a year ago before they went
under. You may want to check again with Delta again.
Maybe they are trying to do you a favor and tell you to simply buy a new
one...knowing the prices of Delta OEM parts too well, it may be cheaper to
replace than to repair especially if your time is worth anything...doesn't
make much sense to me but fact of life I guess...
But if you insist on repair, then I'll add that any Delta DP I've owned
never had springs...loosen the knobs on the sides then move the lever
handles in or out to get a proper belt tension, then tighten the knobs. If
you are truly out of line, then maybe your motor shaft got bent (don't know
how so dubious). Maybe your vibration comes from the fact that the base
isn't sitting on a level surface???
Just some thoughts...
