"Craftsman" is an entire range of tools and equipment and YOU haven't even said what the tool is !
How do you expect a reply giving you a proper answer.
put it on the tension srewand push back towards muffler
Pry up on the tensioner pulley.
The tension pulley has a 3/8" square hole in it. Using a 3/8 drive ratchet or breaker bar, simply put it in and pull the tension pulley.
u need to relaese tension on the tension pulley. this is usually done with a long socket wrench handle. when u release tension and remove belt you then release tension on pulley until you have routed new belt . you then move tension pulley again until you can put belt on it, then release pulley and it will automatically provide correct tension
You need to line up you belt with the pulley except for the tensioner pulley according to the picture in your engine bay. You will need to put a wrench on your tensioner pulley and twist it to relieve the tension then slip the belt on and let off the wrench to return the tension.

A guide pulley helps to change the direction of a moving belt or cable, while a tension pulley is used to maintain the proper tension in the belt or cable.
Try leaving the belt on for tension on the pulley. Also you can very carefully use a pry bar to put extra tension on pulley while belt is on.
To adjust the belt tension on a 42-inch Craftsman riding mower, first, ensure the mower is turned off and the key is removed. Locate the belt tensioner, which is typically near the engine or the pulley system. Use a wrench to loosen the tensioner bolt, adjust the tension by moving the arm, then re-tighten the bolt to secure the new tension. Finally, check the belt for proper alignment and tension before starting the mower.
The tension equation for a pulley system can be calculated using the formula T 2F, where T is the total tension in the system and F is the force applied to the pulley.
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.
