Wheel mounting requiring special tooling
A clad wheel must be centered properly from the back
side of the wheel using precision collets instead of a
centering cone. A precision collet is normally a dual
sided centering device with low tapers on each side
and has a length of approximately 1.5 inches
.
A centering cone can break off the tabs. See section
3.2 Optional Accessories (Pin Plate Set - Spacer).
5.1.1
Unclamping the Wheel
Note:
While the jaws unclamp, hold the wheel so that it
will not tilt when unclamped.
• Lower the brake pedal (Fig. 5-2).
• Remove the quick–clamping nut from the chuck (3,
Fig. 5-1).
• Remove the wheel.
