Changing the Spindle
INVICTA TECHNICAL BULLETIN
Subject: Correct Procedure for Changing Spindles
Pre-installation Instructions
Remove all cosmoline from interchangeable spindle and
mating main spindle before mounting tooling. It is very
important that the locking nut, threads and taper be
clean. Make sure O-ring is in place just below the
bottom lip of the spindle. This acts as a dust shield.
Failure to have O-ring in place will allow dust and
debris to filter down into spindle threads, making it
very difficult to remove the spindle. Lightly oil lower
spindle with 10wt oil before seating.
1. Screw the locking nut (A) up on the fine threads of
the interchangeable spindle (B) until the rubber O-ring
(C) is flush with the bottom lip of the spindle.
2. Then place the interchangeable spindle assembly into
the main spindle and tighten by turning with the nut.
IMPORTANT: Allow spindle assembly to turn with the
nut. Turn until hand tight.
3. Take the spindle nut wrench and turn nut ¼ turn
clockwise to tighten.
CAUTION!!
Do not turn the spindle separately and always return
the locking nut to contact the bottom of rubber O-ring
each time the spindle is removed.
IMPORTANT: All tooling used on the spindle
must be balanced.
