Use of Mounting Hardware
1. The lathe mounting hardware was designed for
use on vehicles with a pressed hub/knuckle/rotor
assembly or where removal of the rotor is difficult or
inefficient.
2. The vehicle’s caliper bolts can be used to mount
the lathe if the holes in the steering knuckle or caliper
mounting bracket are threaded and on the inboard side
of the rotor, Fig. 6. Also, the vehicle’s caliper bolts
should be 1-1/2" in length or longer. Otherwise, the
mounting bolts and nut plates provided in the hardware
package will be needed.
3. Whether you are mounting the lathe with the vehi-
cle caliper bolts or with the mounting bolts provided in
the hardware kit, various combinations of spacers may
be required to take up the space between the bolt
heads and the lathe mounting bracket to keep the bolt
from interfering with the rotor.
Note: When using more than one spacer, care should
be taken to use the tongue and groove configuration to
prevent misalignment, Fig. 7. If the small 1/8" spacer is
required, it should be placed on the caliper bolt last
since it does not have the counter-bore the other spac-
ers possess.
4. The spacers may also be used to achieve the
proper lathe position on the rotor, by placing the spac-
ers on the caliper/mounting bolts between the lathe
mounting bracket and the caliper mounting bracket,
Fig. 8.
5. The flat washers, provided in the hardware kit,
should be used between the caliper bolt head and the
spacers to insure a good seat for the bolt head, Fig.8.
