I acquired a free sears custom snowblower it was missing half the mount so I made my own. I also made my own extension pulley for the engine. So I can't go off of what the original size would be. As the distance between my pulleys maybe slightly different. Anyways they are 5" pulleys 24" apart. By using the math I come up with needing a 63.7" belt. Which would be a 64". But I will have to get a 65" to give it enough slack for the tensioner to kick it on and off correct? If I get a 64" it will be tight all the time. Am I right?

I would think it will need more than 1" slack to disengage properly. Don

I would use the old rope trick. Wrap a rope around the pulleys and make a mark. Measure the rope for the length; get the next size longer and the next size up. Try the shorter one first. It doesn't take much extra belt length to release. The local Family Farm will take the belts back if they have not been run. I have found that the Kevlar belts will stretch a little. Good luck.

Make sure you get the correct width belt also, i.e. 3/8, 1/2, 5/8 in. for the pulleys you are using.

The amount of slack is a consideration, but you must also plan on where the slack should occur.

 

Belt guides should be installed and adjusted to retain the belt on the pulleys, but also to  direct the slack to be around  the drive pulley, preventing belt creep.
