Reverse Rotation
Reverse rotation is used on some vehicles when
excess drag on the vehicle drivetrain prevents
normal on-car operation. The twin cutter insert
holders must be flipped over when using the reverse
function. All other aspects of operation are the
same.
Rotate the twin cutter insert holders as follows:
1 .
Disconnect the lathe AC power cord from the outlet .Loosen
the insert holder lock screws, securing the insert holders to the
cutting tool holder bars .

Disc Resurfacing Procedure
Preparation
1 .
Lift the vehicle and properly chock the wheels .
2 .
Perform a thorough brake inspection . Also check all
suspension, steering, and front drivetrain components .
3 .
Remove the wheel . Disassemble the brake caliper assembly
from the rotor . Observe location of anti-lock sensors and wiring,
if present . Position components out of the way . Support and/or
secure the caliper to prevent damage to the brake hose or other
components .
4 .
Using a micrometer, check the thickness and parallelism of
the rotor from at least three points around the circumference,
about 25 .4 mm (1 inch) in from the outer diameter . If the rotor
parallelism is out of specification, it should be machined .
However, if the rotor thickness is less than the minimum
specifications established by the manufacturer, or if it will
be less after resurfacing, the rotor should be discarded and
replaced .
The minimum refinish thickness specifications may
be found in software or the specification cast into
the rotor. Do not attempt to machine rotors that are
already below discard or "service to" specifications,
or that would fall below after machining.
Mounting Adaptor
The correct adaptor for the vehicle being serviced can be quickly
identified selecting the vehicle in the "Change Vehicle" button on
the tablet . Rotor specifications, lug nut torque and other pertinent,
vehicle-specific data can be found in the same place .
Mounting Options:
For 4-lug nut hubs use four lug nuts to secure the flange .
For 5-lug nut hubs, in most cases, three or four lug nuts
will properly secure the flange .
For 6-lug nut hubs, three lug nuts will properly secure the
flange, mounted on every other stud . This saves time,

allows for clearance, and is stable enough for sufficient
rigidity .
For 8-lug nut hubs, four lug nuts will properly secure the
flange, mounted on every other stud . This saves time,
allows for clearance, and is stable enough for sufficient
rigidity .
If OE lug nuts interfere with mounting, use Accessory Kit 20-1503-1.

1 .
Verify that all mounting areas are clean . Use a wire brush to
remove rust build-up if necessary .
2 .
Attach the proper adaptor to the rotor face by using the
vehicle's lug nuts . Torque the lug nuts to 40 ft-lbs/54 .23 Nm
(maximum) .

Mounting the lathe to the Vehicle
Only mount the lathe to the adaptor with the e-Stop
button depressed
1 .
Mount the lathe the adaptor assembly . Line up the index pin on
the compensation device with the index mark on the adaptor .

2 .
Tighten drawbar with the 22mm wrench provided with the
lathe . Tighten the drawbar entirely and then back it off one
wrench flat . It is important that all contact surfaces between the
lathe and the hub flange assembly are clean to ensure proper
alignment and fit . Double check adaptor and lathe alignment
and all associated clearances .
The following items may slow or prevent ACE
Compensation Procedure
compensation:
1 .
Press the "Comp" button to begin compensating . The LED next
to the button will illuminate .
a) Excessive movement and free-play of vehicle
suspension parts.

b) Excessive movement of the vehicle on the lift
2 .
Speed can be adjusted by either turning the Speed knob on the
during compensation. If necessary, the vehicle
console, or using the slider on the tablet . The tablet also shows
should be stabilized with the vehicle lift placed on
the progress of the compensation .
its locks. The vehicle should not be disturbed during
compensation.

c) Failure to properly assemble and/or tighten the
mounting and adapter to the vehicle before attaching
the lathe. Remove any dirt and rust buildup on the
rotor face and backing plate.
Adjusting the Twin Cutter Assembly and Cutting
the Rotor
1 .
With lathe mounted on the adaptor, loosen the twin cutter
assembly shaft locking bolt and adjust the shaft to the
appropriate distance from lathe to rotor surface, by sliding shaft
inward or outward (see image below) . Retighten the shaft lock
bolt after positioning .
Image 28.
2 .
Remove all tools from the adaptors and lathe .
3 .
Before starting the lathe, position the cutting inserts at the
midpoint of the rotor's inboard and outboard friction surfaces by
turning the rotor feed control until the cutters are in the proper
position .
Verify that cutting inserts are not in contact with the
disc rotor surface at this time.
