These AMMCO brake lathe adapter sets are for use with applications that include cast hubless rotors, composite rotors, drums and ﬂywheels. The ﬂange plates included in the sets simulate actual vehicle mounting. These sets are for use on any brake lathe with a 1 inch arbor.

Before You Begin

It is important in any machining operation that all adapters and mounting hardware, as well as the rotor, drum or flywheel to be machined, are clean and free of nicks.

Typical Adapter Usage for Rotors

Figure 1 illustrates the typical adapter usage.

1. Determine which flange plate is most appropriate for the current application and place it on the arbor.

IMPORTANT: The ﬂange plate must contact the ﬂat portion of the rotor hat, but must not contact the rotor anywhere around the outside radius. Always use the largest ﬂange plate possible.

2. Place the spring onto the arbor and into the ﬂange plate. Twist it counterclockwise to hold it in place.

3. Select the cone that best fits the rotor center hole and slide it onto the arbor wide end ﬁrst.

4. Slide the rotor onto the arbor, locating the center hole over the cone. Push rotor and cone back against spring and ﬂange plate.

5. Slide the largest remaining ﬂange plate (that ﬁts rotor as speciﬁed in step 1) onto the arbor.

6. Fill out the arbor with spacers as required to secure entire rotor assembly to the arbor.

NOTE: On AMMCO lathes, the last item placed on the arbor before the arbor nut must be the self-aligning spacer.

7. Tighten the arbor nut by either rotating the rotor while holding the arbor nut until they lock up, or by using a wrench to turn the nut until the rotor begins to turn and then continuing to advance

the wrench Z\zn of a turn. Do not overtighten.

Odd Conﬁgured Cast Hubless Rotor Mounting

Figure 2 illustrates these mounting procedures.

1. Determine which flange plate is most appropriate for the current application and place it on the arbor.

IMPORTANT: The ﬂange plate must contact the ﬂat portion of the rotor hat, but must not contact the rotor anywhere around the outside radius. Always use the largest ﬂange plate possible.

2. Place rotor onto arbor. Note that some rotors may need to be mounted backwards so that the rotor’s machined surface contacts the first ﬂange plate.

3. Slide the 29573 reversible centering cone onto arbor and into the rotor center hole with the cone taper facing the rotor.

Mounting Drums and Flywheels

For drums and ﬂywheels, refer to Figure 1. Use the same techniques as described in Typical Adapter Usage for Rotors.

NOTE: When mounting drums, use the largest flange plate possible inside the drum. The flange plate must be as large as possible but still allow clearance for the boring bar. On smaller drums, use the 29573 Reversible Centering Cone as the inside ﬂange plate to allow for proper boring bar clearance.

Always refer to your lathe operating instructions for additional information and procedures about reconditioning rotors, drums and ﬂywheels.
