Rotor Mounting - AMMCO 3000 Installation Instructions Manual

Rotor Mounting

Review the descriptions of mounting a brake drum on
page 6. The same directions apply when mounting a
brake rotor. Hubbed rotors are mounted on adapters
that fit into the bearing races. Hubless rotors use a
cone in the center hole and a hubless adapter on each
side of the rotor. Spacers are used to fill out the arbor
shaft so that the arbor nut can be tightened. The
setups illustrated in Figure 20 are typical of the many
mounting configurations necessary to meet the
requirements of brake rotor reconditioning. The
adapters, cones, and spacers supplied with the lathe

will allow reconditioning of the majority of the rotors
found on current production vehicles. Optional
adapters, cones, and spacers are available to meet spe-
cial needs.
Note: Adapters may also be used as spacers to fill out
the arbor shaft if care is taken to prevent damage to
their machined surfaces.
The patented self-aligning spacer prevents diagonal
thrust on t he adapters. The self-aligning spacer should
always be used adjacent to the arbor nut.
