The drive belt turns the lower wheel to turn the blade. If the drive belt breaks, the motor runs but the blade won’t move. Replace a broken band saw drive belt with the manufacturer-approved band saw part.
Position the drive belt on the lower wheel pulley and, while sliding the wheel onto the shaft, wrap the drive belt over the motor shaft. Locate the tension knob on top of the band saw, which typically is on a vertical shaft above the band saw’s top cabinet. So check the alignment with the blade under tension, plus some more tension to account for the additional blade tension due to the cutting forces.
Then with a pair of snap ring pliers remove the snap ring in the center of the lower drive wheel. Then remove the old belt and put the new one on the pulley. Now push on the motor to tighten the belt and tighten the mounting screws.

How tight should a sawmill blade be?
For carbon steel toothed blades (cutting blades) this is typically 15,000 to 25,000 PSI. Slitting type blades typically are tensioned in the range of 12,000 to 20,000 PSI. In general bandsaw blades are never tensioned past 35,000 psi.
How do you maintain a bandsaw blade?

Can you sand with a bandsaw?
Now you have a belt sander that can sand parts as tall as your bandsaw capacity.
