4. a. Select proper size bell clamps and slide one on the arbor.
b. Slide spring on the arbor.
c. Find the centering cone adapter that fits the
center hole of the drum or rotor and slide it on the
arbor.
d. Slide the drum or rotor on the arbor and then the other
bell clamp.
e. Add necessary spacers (double tapered radius adapters may
be used as spacers), alignment washers (make sure they
are installed concave to convex), hex nut and tighten
securely. Do not jerk or over tighten. (See example on
page 15)
5. WRAP RUBBER SILENCER BAND AROUND DRUM, STARTING WITH THE
PLAIN END AND MAINTAIN TENSION UNTIL THE CLIP IS SECURED. DO
NOT ATTEMPT TO MACHINE DRUMS WITHOUT USING THE SILENCER BAND.
Silencer should be nearest open side of drum. Silencers
should also be used for rotor machining.
6. If arbor appears distorted, check for rust, burrs or chips on
cones, drum or rotor, bell clamps, spacers, arbor or other
mating surfaces.
7. Composite hubless rotors may require optional composite
rotor adapters.
Mounting Hubbed Drums or Rotors
1. Select the double tapered radius adapter that properly fits
the inside of the large bearing race. It should sit in the
race similar to a bearing and move side to side in all
directions easily. If it binds in any direction, this is an
indication of an incorrect adapter selection or a damaged
bearing race. Correct problem before proceeding.
2. Slide the double tapered radius adapter all the way onto
the arbor. If the drum or rotor contacts the lathe, a spacer
may be required between the double tapered adapter and lathe.
3. Using the same procedure as in Step 1, select the double
tapered radius adapter for the outside race.
4. Install the drum or rotor and position it on the back double
tapered radius adapter and then slide the front double tapered
radius adapter on the arbor and into the front race.
