INSTALLING NEW BELT

I'm sorry, but I do not have access to the instruction manual for the Ryobi HBT250 Table Saw. However, I can provide you with some general guidance on how to reinstall the motor on your table saw.
First, make sure you have all the necessary parts and hardware before you begin. Before installing the motor, check that the motor pulley is properly aligned with the arbor pulley, and that the belt is properly tensioned.
Next, you will need to mount the motor to the table saw. To do this, you will need to align the motor mount holes with the holes on the saw's base. Once the holes are aligned, use the bolts and washers that were provided with your saw to secure the motor to the base.
Once the motor is mounted, you will need to connect the electrical wires to the switch and power source. The wires are usually color coded, with one wire being black or white (neutral), and the other wire being a different color (hot). The neutral wire should be connected to the white terminal on the switch, and the hot wire should be connected to the black terminal.
After the motor is mounted and the wiring is connected, you will need to test the saw to make sure it is running properly. Turn on the saw and let it run for a few minutes to ensure that the motor is running smoothly and that the belt is properly tensioned.
If the saw is running properly, you should be all set. However, if you are still having trouble, it may be helpful to consult the instruction manual for your specific model of saw, or reach out to a professional for assistance.
Keep in mind safety instructions when working on the saw. If you don't feel comfortable with the task reach out to professional or consult the manual.

Huh??? According to my parts manual you need an "2YFD" belt. ereplacementparts.com has it for $3.88 be sure to check that this is the belt you want BEFORE ordering it.
Sears should have it. How do you know Sears does NOT sell this part?

You must lower the motor down as far as possible and then tilt the saw blade so the back end of the motor where the belt is housed is exposed and accessible as possible. Then remove the cover housing at the back end of the motor. This will expose the belt. Thenyou can remove the old belt and install the new one.

If I understood correctly, you started using your husband's table saw and while ripping boards, you managed to stall out the blade AND motor?! If that's the case, you probably have a very dull blade and are binding your board on the blade. Neither is safe and it sounds like trouble is brewing.

First and foremost, get someone to show you how to safely and properly use and adjust the saw if you are new to wood working and power tools. That saw is capable of turning your lumber into a high speed missal if you do things improperly.

It also sounds like you tried installing a new 10" saw blade. Changing the blade requires 2 wrenches. One to hold the arbor and one to tighten the nut. The blade itself should rest on the arbor between two large washers. Also make sure you install the blade so the front face of the cutter teeth face you and rotate toward you. Make sure the saw is unplugged when changing the blade and never turn on your saw with a loose blade.

Is the belt still on? Does the motor's weight hang smoothly down on the belt to keep tension?

Check nameplate on motor for amp draw, and then check that against your breaker and wire size.

If table saw worked on the breakers before and suddenly stopped working, then see if you can lubricate motor bearings >> look for oil cap on each end of motor and use 3-in-1 oil.
Clean the saw and make sure there's nothing rubbing against drive belt and that saw blade rolls easily when saw is turned off.

if you get the model number of the saw to me, i can get you the part number and source for the correct belt.
