‐Inspect the variable transformer drive belts, sprockets, gears, cams, etc. for signs of slippage or wear
and adjust as required.
‐Check the variable transformer radiator(s) (the die cast part that holds the brush assembly) for signs of
slippage, and see if all brushes driven by the same motor are aligned with each other. The alignment
of the radiator and brushes depends on the setscrews that hold the variable transformer center tube(s)
