Compressor, engine and gearbox casing repair
Bearing-bore wear, split-line distortion and oil-leak paths at gasket faces retire compressor, engine and gearbox housings before the internals wear out.
What is failing
Bearing bores wear oversize, split lines distort, and oil weeps from gasket faces long before the internals reach end of life. A cracked or eroded housing pulls the whole machine out of service. Replacing a compressor, engine, or gearbox casing means OEM lead times measured in months and a capital line item that dwarfs the original defect.
How AAS does it
AAS rebuilds worn bearing bores and split-line faces cold in our climate-controlled shop or at your site, with no welding heat to warp the casting. The crew prepares the metal, applies a machinable repair composite such as Belzona 1111 or 1121, then machines the surface flat and back to dimension. The bore and gasket face return to OEM tolerance without an arc.
Typically applied with Belzona 1111, Belzona 1121, matched to the service conditions.
The housing goes back into the same outage instead of waiting on a replacement casting. The plant keeps its alignment datum and avoids a long-lead capital purchase.
