[C320-list] Schaefer 2100 furler bearing replacement

[Chris Burti]

As an additional FYI...when the bearings are not flushed properly over
a long period of time and are forced by using a winch or by brute
force, they will become damaged and no amount of flushing will cure.

The inability to easily and properly flush the bearings is an
acknowledged design flaw. As a result Schaefer has been supplying
existing owners of these damaged units a replacement drum at a heavily
discounted price.

The new drums have openings in the top so they can be flushed from the
top down and they use larger bearings with wider spacing to allow gunk
to wash out more easily.
