[Farmall] OT-Need help with Sears 20HP Onan powered garden tractor

[Frank DeWitt]

That clutch was probably NOT made by Sears or onan.  It was probably made 
by Warner Electric
http://www.warnernet.com/

You may be able to get some help by studying there web site.

There are 3 main parts.
one part attaches to the drive shaft (engine) and spins all the time.
The second part contains the pulley and spins with power applied.
The 3rd part contains the coil and never spins.  This part is usually keept 
from spinning with a single lose pin or shoulder bolt or a sheet metal 
bracket to just one place on the clutch. (it is not hard mounted because 
that would put stress on the bearing.)  It will look very weak but that is 
intended.  The engine shaft does all the work.  I would not be afraid to 
make a link if the correct one has been destroyed.

Sorry I don't have a more specific answer.
