Re: (ET) Mower motor bearing replacement

["SteveS" <ssawtelle fcc net>]

Look in the files section of the site:

http://groups.yahoo.com/group/elec-trak/files/ET_PARTS.txt

When I was searching for similiar info, I put everything I found in this
file to help out the next person(s).

Now, I have the small diameter motor, so I can't vouch for the bearings
listed for the large dia motor, but I believe the info to be right as it 
was
listed a couple times in mesages and never contradicted.

anyone have the actual bearing numbers for the 4.5" dia motors handy?  I
need to re-cross reference them.
