I purchased my electric White Mountain ice cream freezer in 1993.  One of the reduction drive gears finally wore out in the head unit.  Like other reviewers, I'm finding that you cannot purchase components (bushings, gear sets, etc.) to repair these great old ice cream makers.  An electric head unit (motor and drive assembly) can be purchased, but they're cheap Chickity-China garbage!!  Hand crank units are still available, but I've heard the late model ones also have cheap Chinese made gear sets (some plastic) and will not last for more than a few batches of ice cream!  What a shame this company is trading off the old reliable reputation of one the last traditional American made products.  Guess I'll just have to design my own drive unit.
