If you remove the housing, drill a small hole at each end of the crack to prevent further travel. Sand anywhere the epoxy will contact. Then drill a couple of holes along/through the crack. Push the epoxy through all of the holes adding a light coating of epoxy to each side of the crack connecting the drilled through holes...good to go forever.

Good luck!!!
