Expert Tip #3 – What to do about Bead damage
Many costly Earthmover tyres are scrapped due to minor damage in the Bead area. The solution is Monaflex’s XLBRS – the only system that can conform to the complex profile of the Radial Bead area.
Here’s a step by step guide to preparing the injury for curing with the Monaflex system.
- Cut away loose rubber around the Bead damage with a knife
- Remove and buff the rubber around the injury with a rasp on a low speed buffer. Texture to RMA#2
- Taper perimeter edges of the injury to a 60° angle – keep the texture to RMA#2. NOTE: If necessary, it is ok to remove chafer strip from the damaged area. On a bias tyre a maximum of one ply of fabric may be removed. If the Bead cable shows any sign of damage do not attempt a repair.
- Apply two coats of black cement to the whole area, allow each to thoroughly dry
- Cover the buffed area with a layer of cushion gum, ensuring it is thoroughly stitched down with no trapped air bubbles
- Fill and stitch down the remaining area with tread gum to a height of 1/8″ above the surrounding area
- Ensure that there is no trapped air
- Use a knife to trim any excess rubber to the contour of the Bead
- Cover the injury with high temperature poly or Holland cloth to protect and prevent adhesion to the Heat Pad
- Use a specialist Monaflex Bead Repair System to cure the injury – see this process here.
- Allow to cool to room temperature and use a rasp in a low speed buffer to match the contour and texture of the Bead.
Please always adhere to the guidelines set by repair material and tyre manufacturers.
