Installation Tips for Automatic Brake Adjuster (79620)

Proper installation is critical to ensure the automatic brake adjuster functions correctly and maintains vehicle safety. Follow these essential guidelines:

1. Vehicle Safety Preparation: Park on a flat, stable surface, chock the wheels, and fully depressurize the air brake system before beginning any work.

2. Clean and Inspect Components: Thoroughly clean the brake camshaft splines. Any dirt, corrosion, or damage can prevent the automatic brake adjuster from seating properly and impair its automatic adjustment function.

3. Correct Positioning and Alignment: Align the splines and slide the adjuster onto the camshaft. Ensure the control arm is positioned correctly according to the vehicle manufacturer’s specifications (often indicated in documentation) to allow for its full range of motion.

4. Secure the Mounting Bolt: Tighten the clamp bolt to the manufacturer’s specified torque value. This is crucial to prevent the adjuster from slipping on the camshaft, which would disable its automatic function.

5. Connect the Control Linkage: Attach the control arm to the brake chamber pushrod or its designated linkage point. Ensure all connections are secure and that the movement is free without any binding.

6. Pre-Operation Check: Before finalizing, manually back off the adjuster (if required by the specific model) to provide initial clearance. Refer to the product manual for any specific pre-set instructions.

7. Final Verification: After installation, re-pressurize the air system. Apply and release the brakes multiple times in a safe, controlled area to allow the automatic brake adjuster to self-set and perform an initial adjustment. Always conduct a full brake system test before returning the vehicle to service.

Important Note: This is a general guide. Always prioritize and consult the official vehicle service manual for model-specific procedures, torque specs, and safety warnings.
