Oil Pump Epoxy Repairs for the Aerospace Industry

Although Component Repair Management offers a variety of metal welding, electron beam welding, brazing, and metal blending repair and salvage services, the veteran company turned to epoxy for the repair of components for one of their customers in the aerospace industry. The customer requested a salvage repair of gear bores and gear pockets for the bodies of Rolls Royce 250 oil pumps, requiring the replacement of bearing cages and bushings when needed. Following conventional machining, Component Repair used epoxy polymers to repair magnesium and aluminum gear bores and pockets on oil pump bodies up to 1" thick. Epoxy repairs were followed with sanding and cleaning before the components received an epoxy coating finish. These 8" long by 6" wide components were repaired to tightest tolerances of ± 0.0005", all to rigid customer specifications and all applicable airworthiness standards. Dimensional inspection in addition to fluorescent penetrant inspections were used to eliminate the possibility of defects in these pump components. Component Repair repairs 20 to 35 of these oil pump body components per month in only one to two weeks.

Component Repair’s certified staff has the experience and ability to bring the proper repair process to restore the air worthiness of aerospace components. For further information, contact Component Repair Management today.
