Technical Advice: Dust seals are the first line of defense for the excavator's arm bearing system. Their damage or absence causes grease to mix with sand, creating an abrasive paste that can destroy the pin and bushing in a very short time. When replacing bushings, always install new AZERI PARTS seals. Before seating the wiper, ensure that the housing in the boom lug is cleaned of rust; this will prevent it from being pushed out by grease pressure during machine lubrication.
