The bush in the top of the motor seized up due to water ingress and corrosion. Stripped and cleaned,and replaced the brushes, in the process of rebuilding I have broken fingers off the bush locator in the top plate, this resulted in the unit being very noisy, (but working). Latest attempt was to glue the bush in with Devcon, much better result. Do you think this will last if not where can I get a new top plate? After market replacement of motor in Aus is $400
