Gear motors and water seals Nugget and flake
Scotsman’s nugget and flake machines make ice with an auger, a screw turning inside a freezing cylinder and driven by a gear motor. At the bottom, a water seal keeps water out of the drive. When that seal wears, it leaks, and if water reaches the gears, they start to whir, grind and wear out.
Colby replaces the seal and, if the gears are damaged, the gear case too.
