Installation Tips for Automatic Slack Adjuster (79365)

Proper installation is critical to ensure the slack adjuster automatic functions correctly and maintains brake system safety. Follow these essential steps for a successful installation:

1. Safety Preparation: Park the vehicle on a level surface, chock the wheels, and fully depressurize the air brake system before beginning work.

2. Inspect and Clean Components: Thoroughly clean the brake camshaft splines and check for wear or damage. Remove any dirt, rust, or debris to ensure the automatic slack adjuster seats properly and functions correctly.

3. Align and Secure the Adjuster: Carefully align the splines of the automatic slack adjuster with the camshaft. Push it into place until fully seated, and tighten the clamp bolt to the manufacturer’s specified torque to prevent slippage.

4. Connect Linkage and Verify Movement: Attach the brake chamber pushrod to the clevis and secure it with a new cotter pin. Ensure all connections are tight and that the adjuster moves freely without binding.

5. Initial Operation Check: After installation, re-pressurize the air system and apply the brakes several times in a safe environment. This allows the slack adjuster automatic to self-adjust and set the correct brake clearance.

6. Final Testing: Conduct a thorough brake test to verify proper operation before returning the vehicle to service. Check for air leaks or abnormal noises during braking.

Note: Always refer to the vehicle manufacturer’s service manual for detailed instructions and torque specifications to ensure compliance with safety standards.
