Looks like blade hung in rock, the motor kept turning,belt fried.18 IN HP. I need advisement on the easiest and proper way to put a new one on.Looks like the only option is to pull the outside bearing off,correct? Need puller,etc? Any help would be greatly appreciated. These are uncharted waters for me. Thanks, snuffy

I replaced the leather one on my 14" HP by finding a regular black belt that was the right size cut it in half and used a strong staple/wire to hold it together hardest part was punching the holes for the staple/wire

Hmmm...either that or go with one of the "braided" ones they sell for table saws, they can be put together without piece removal. Not sure that description makes sense, will try to find the info from the one I bought. Was running a 3HP table saw with it and hogging some pretty tough cuts with no problem, would think it would work..??

This would be easier (unless I don't see the issue in the photos): I think you can just unbolt the left bearing, loosen the right bearing, and slip the belt over the pulley and bearing. No need to take the bearing off the shaft.

The collar on the outside of the arbor should have a set screw in it. Maybe 2 set screws. Loosen the screws and slide the collar off. Remove any burrs left on the shaft with sand paper or a smooth cut file. Next, remove the bolts holding the outside pillow bearing, and slide the bearing off. You mat have to clean the shaft real good, and tap the bearing off with a mallet. Now you should be able to remove the old belt, and put a new one on. It would be helpful to scribe a mark at both ends of the pillow bearing before removing it. When you put the bearing back on, line it up exactly on these marks. If you move that outer bearing to the front or rear just a little bit, your blade won't be in line with the travel of the vise. This will cause the blade to pinch in every cut you make.

If the outer bearing has two setscrews remove them and slide bearing off after removing bolts. If there is one set screw and a dimple, remove the set screw and with a punch or screw drier in dimple tap opposite rotation and remove collar. Then unbolt. When you reinstall tap concentric collar in direction of rotation. As said above mark bearing location and put back exactly where it was. Make sure vise/carriage is perpendicular to blade when done. Poor man's dial indicator is a marking pen in vise that just touches blade. Slide along entire blade surface.

Thanks everybody for your input. The solution boiled down to removing 1 bolt that held the aluminum belt guard, loosenig the other and moving the guard over to allow the belt inside. The belt just looped over the assembly.This after I loosened the bearing enough to slide the belt under it and realized that was wrong. I'll know next time. She's sawing away now.
