How can I replace the transmission drive belt on my Troy-Bilt Riding Mower?

The problem I am having is that the largest pulley is about 3/4 of an inch from inside the casing but the belt itself is about a whole inch thick. Do I have to remove the pulley to get the belt around it?

sometimes it is easier to remove the pulley, put the belt around it, and pull the pully into its proper place and once its juuuust on its pin, use a block of wood and hammer to pound it back down.



unplug the spark plug so it doesnt start on youHow can I replace the transmission drive belt on my Troy-Bilt Riding Mower?Everyone here seems to think you are writing of the front of the machine. It is the belt under the seat.

You need to undo the large center nut and pull off the pulley. The pulley is on a spline, so be careful how you release the pulley. You might need to expand the pulley a little by heating it with a blow lamp, then the pulley will slide of the splines easier. Don't forget to use leather gloves, as your hands can get hurt pulling off the pulley, eh. Slide the new belt on and replace the pulley.

Best of luck.
