Monaflex, a Guernsey, Channel Islands, company that specializes in vulcanized repair solutions for the industry, recently offered a checklist that can be used by tire-service teams to ensure that OTR tire repairs are done in the most efficient and effective way. The tips recommended by Monaflex include:
• Use Quality Supplies – From tools to rubber, patches and vulcanizing equipment.
• Train Your Team – Ensure technicians are properly trained in all aspects of the tire itself as well as the repair process. Do they understand:
-How all the tire components — tread, sidewall, bead, bead wires, body plies etc. — work together?
-The correct way to use all tools and equipment?
-How to properly build up and install a repair to ensure maximum adhesion?
-The best protocols for safe working?
-The importance of a clean working environment and how to achieve?
• Inspect the Injury – Include a comprehensive inspection process assessing the injury’s size and its location in the tire:
-Is there an economic case for making the repair? What is its general condition? How much tread is remaining?
-Is there more than one injury or less obvious damage to consider?
-How far below the surface does the injury extend?
• Assess the Repair – Consider the following:
-What tools are required?
-How can you remove the structural damage?
-What is the correct skive angle and buff texture?
-What is the right patch? Consult patch manufacturer application charts.
-What is the best and safest method of using the chosen vulcanizing system?
• Understand Your Vulcanizing System – Get to know your OTR vulcanizing system. Get the right training and adhere to best practice usage guidelines. Use the correct components for the job to ensure a perfect fit and optimum results. Always consult component application charts.
• Conduct a Final Inspection – This stage is as important as the initial inspection.
-Did the technician find and repair all damage?
-What does the repair look like? Are there signs of under cure, bubbles or separation?
-Record the Shore Hardness.
-Can you return the tire to its original operation, or should it be downgraded? Example: Use the repaired tire on a slow-moving water-wagon versus a production hauler that travels long distances at higher speeds.
