Rotor Mounting Adapter

^ Tools Required
- J 37160-A Rotor Mounting Adapter
- J 37160-50 Rotor Mounting Adapter Sleeve

Important: Verify that the mounting surfaces of these components are clean and free from nicks, burrs or rust.

1. Inspect all of the mounting hardware for the following conditions:
^ Rust
^ Nicks
^ Dirt
^ Abnormal wear
For proper results, ensure that all components are in good condition and clean.
2. Inspect the rotor:
^ Measure the lateral runout. Refer to Brake Rotor Lateral Runout Check.
^ Measure the thickness variation. Refer to Brake Rotor Thickness Variation Check. Ensure that the mounting surface of the rotor is clean and free from rust and nicks.
3. Mount the J 37160-A on a spindle arbor.
^ Use a suitable combination of spacers or collets in order to tighten the J37160-A to the arbor.
^ When using lathes with a 7/8-inch spindle arbor, use the J 37160-50 with the J 37160-A.
^ The J 37160-50 is not required with lathes using a 1-inch spindle arbor.

Notice: Refer to Fastener Notice in Service Precautions.

4. Mount the rotor onto the J 37160-A
^ Mount the clamp plate to the rotor using the enclosed bolts/screws.
^ The rotor may be installed and removed while the J 37160-A is mounted on the machine spindle.
^ Tighten the rotor mounting adapter nuts in a cross pattern to 34 Nm (23 ft. lbs.).
5. Install the anti-chatter silencer onto the rotor.
6. Set the spindle speed to approximately 150 RPM (or mid-range).
7. While the machine is running, bring the tool bit up and touch off.
^ Stop the machine.
^ Inspect the witness mark. If the witness mark goes 3/4 of the way around, the rotor is mounted properly.
^ Continue turning the rotor using normal methods in order to resurface the rotor.
8. If the witness mark does not go 3/4 of the way around, repeat the above steps.
