814 Heavy Equipment Safety

Servicing Multi-Piece Rim Wheels

Precautions and Procedures

Prior to initial servicing, workers must be trained by a competent person, review specific instructions provided by the tire manufacturer, comply with the specific OSHA rules in 29 CFR 1910.177, Servicing multi-piece and single piece rim wheels.

Below is a general overview of the steps in safely servicing multi-piece rim wheels:

• Training and Competency: Ensure that workers involved in servicing multi-piece rim wheels have received adequate training on the proper procedures, safety protocols, and hazards associated with the task. Workers should be competent in using the necessary tools and equipment.
• Personal Protective Equipment (PPE): Before beginning any work, ensure that workers are wearing appropriate PPE, such as safety glasses, gloves, and steel-toed boots, to protect against potential hazards.
• Equipment Inspection: Inspect all tools, equipment, and components before use to ensure they are in good working condition and free from defects. This includes inspecting the rim, lock rings, wheel rings, and tire for any damage or signs of wear.
• Deflating the Tire: Prior to removing the tire, deflate it completely using a proper tire deflation device or valve core removal tool. This step is essential to minimize the potential energy stored in the compressed air.
• Lock Ring Removal: Carefully remove the lock ring by following the manufacturer's instructions. Use appropriate tools and techniques to prevent any sudden releases of energy or dislodging of components.
• Dismounting the Tire: Use tire removal tools and techniques to safely dismount the tire from the rim. Take precautions to prevent flying debris or potential pinch points during this process.

• Inspection and Repair: Inspect the rim, wheel rings, and other components for any damage, corrosion, or wear. Repair or replace any damaged or worn components as necessary before proceeding.
• Mounting the Tire: Position the tire on the rim, ensuring it is correctly aligned with the valve stem. Follow proper mounting techniques and use suitable tools, lubricants, or bead seating devices as recommended by the manufacturer.
• Lock Ring Installation: Carefully install the lock ring according to the manufacturer's instructions. Make sure it is securely seated and fully engaged, taking precautions to prevent any sudden releases of energy.
• Inflation and Testing: Gradually inflate the tire to the recommended pressure using a suitable inflation device. Regularly inspect for any signs of air leaks, tire bead seating, or abnormalities during the inflation process.
• Final Inspection: After completing the tire installation, conduct a final inspection to ensure all components are properly installed and secure. Verify that the tire is correctly seated on the rim and that there are no visible defects or abnormalities.
• Cleanup and Maintenance: Clean the work area, properly dispose of any waste materials, and store tools and equipment in their designated places. Regularly maintain and inspect tools and equipment to ensure they remain in good working condition.

Remember, the steps outlined above provide a general overview only, and should not be used for servicing specific multi-piece rim wheels. Comply with manufacturer instructions and OSHA rules in CFR 29 1910.177. Failure to do so could result in a fatal accident.
