[Farmall] Super M Fan Belt

Hi Mike.  Guess I should go check the belt tension... :-)

Dean's procedure will work, but it won't get your new belt tension set 
correctly - you need to undo the set screw on the fan pulley and turn 
half the sheave in or out to adjust the tension. A flat bar and a small 
hammer might be needed to get things moving in the right direction 
(there are raised lumps on the pulley hub for that purpose, but it 
doesn't/shouldn't take a lot of brute force; a little penetrating oil 
will help to make things easier). It helps to have a copy of the 
operator manual for an illustration.

If you spread the sheave out first, you can pull the belt off the 
crankshaft pulley relatively easily and not bother with removing the 
plugs, etc. You will likely skin at least one knuckle on the radiator 
fins, but that seems to be about normal for me.
