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.

REMOVAL PROCEDURE
1. Inspect all 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 J 37160-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: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

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.
