Abstract

A system for repairing leaks, cracks and crevices in a stator assembly of the type having a fluid cooling system. The system includes an anaerobically activated, liquid polymer curable sealant supply which is circulated through the fluid cooling system of the stator assembly. Sealant connectors place the sealant supply in fluid communication with the cooling system and a pump circulates the curable sealant supply through the cooling system to repair the leaks, cracks and crevices in the stator assembly. In the preferred embodiment, a secondary curing system provides an initial curing of the curable sealant to form a protective 'skin' after the removal of the excess curable sealant from the fluid cooling system.
