Small Engines (Lawn Mowers, etc.): my grandfather is trying to..., power path, crankshaft

Question
my grandfather is trying to install a belt, but he can figure out how to get it back on. i was wondering if you could send the insturctions on how to do it?

Answer
Hi Michelle,

Sorry, I don't have detailed instructions.  He will need to trace the power path, starting from the crankshaft.  While noting the rotation of the crankshaft and the blades, follow each pulley.  The backside of the belt will probably go around the idler/tensioner pulley.  The belt will usually fit only one way, so after some trial and error, it should work out easily.

Good luck,
Michael
