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 bent or distorted, check for rust, burrs or chips on the 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 on 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.
Bearing race should be clean and free from excess grease.
2.
Slide the double tapered radius adapter all the way onto the arbor. If the drum or
rotor contacts the lathe, a spacer (double tapered radius adapter) o f the largest size
available may be required between the double tapered adapter and the lathe.
On
hubless drums, this extra double tapered radius adapter will be required
before the bell clamp is installed on the arbor almost 100% of the time.
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.
5.
Use adapters or spacers as necessary to space out to the end of the arbor.
(See Fig. 1). Double tapered radius adapters may be used as spacers. Install nut
and tighten using a slow steady pull. Use spanner wrench on spindle to hold spindle
while tightening.
Do not hit or jerk 1 1/2" wrench while tightening.
6.
Wrap rubber silencer band around drum, starting with the plain end and maintaining
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 specified for
rotors should also be used for rotor machining.
7.
If arbor appears bent or distorted, check for dirty or damaged mounting surfaces and/or
adapters. Loosen and re-tighten arbor nut as described above in Step 5.
