Belt change on an SM is not terribly difficult:

1 - Loosen (unscrew) both the generator and water pump adjustable sheaves. Do this by unscrewing the locknut and 1/4" set screw in the rear halves of the water pump and generator sheaves, then unscrewing the each sheave half as far as it will go. This will loosen the belts. Plan on finding the adjustable sheaves being stuck on their threads - a liberal application of WD-40 and some quality time with a hammer and punch are often required. (Note: This is usually the most difficult step - often it's easier to simply cut the old belts off THEN attack loosening the adjustable sheaves.)

2 - Once you get the sheaves opened up all the way, walk the fan belt off the crank sheave, then off over the fan blade and out of the fan shroud. Then repeat the process with the generator belt (despite how small it looks, the gen belt WILL fit over the fan blade!)

3 - Now reverse the process to first install the new gen belt, then the fan belt.

4 - Once the belts are in place, set the belt tension by tightening the adjustable water pump and generator sheaves. Lock the sheave adjustments with the set screws and locknuts.

Note: These belts don't need to be very tight to work properly. About 1-1/2" of mid-span slack in the fan belt and 1" slack in the generator belt is good.
