Overhauling of electric motor means renewal of worn out
ball bearings, cleaning of winding/ internal with CTC,
inspecting the winding with Megger, inspecting of rotor
with growler, inspecting for any bend in shaft, inspection
of bearing housing, grease route, making any defects
alright, ensuring it is rady for further operation of
another two years. Rebalancing of running parts
recommended. The motor should be water proof after the
overhaul. Anticorrossive paint should applied externally.
