[AT] IH cub

[George Willer]

Mike,

Cecil has had the second Cub for only a short while, but I think he's been
responsible for maintaining Lucille's Cub for a while.  :-)

The main transmission shaft has two bearings.  (and the PTO shaft bushing)
The front one and its' seal are subject to corrosion problems if the hand
hole cover is left off and the mice build a nest in the torque tube.  The
rear one is more likely to be the noisemaker due to its' poor design.  It's
a roller bearing running directly on the shaft, and the shaft surface
wears... leaving no way to replace it with original parts unless the shaft
is also replaced.  Some of us have done a modification to the shaft that
allows using a real bearing.

I'll be taking two Cubs to the Cub Fest that have the noise problem.  When I
think about the work required to make the noise go away, it doesn't seem so
loud!
