* Machine the worn area down 3mm (0.125 in) to produce a square shoulder on part. The material is stronger with a square edge versus a feathered edge.
* Machine a spiral cut in bottom of area to be repaired to provide mechanical keying into surface.
* Apply excess product to ensure small shrinkage during cure does not produce depression. Machine the surface to original dimensions prior to full cure, as the product is very wear resistant.
LOCTITE® EA 3478™ is a two-part ferro-silicon filled, 100% solid epoxy resin system. It is ideal for restoring parts worn by mechanical impact and/or corrosion. Typical applications are restoring tolerances to worn shafts, repairing worn keyways, repairing damaged housings, filling pitted surfaces in worn machinery, and restoring fit to bearing housings.
