Last year I purchased a Toro 724 with a seized motor. this year I purchased the Predator 6.5 hp motor from Harbor Freight. I have attached some Pictures of the progress so far but any info on what else I will need to purchase would be great! I also have read the Thread on a similar Toro 724 that was repowered, but still not exactly 100 percent on everything I need or where to get it! thank you all in advance!

If you're not able to get a part number off the old belt, or have to modify the engine position or bought a larger pulley, then just bring the old belt to an auto parts store and they can measure it. If worse comes to worse, but a few of them in different lengths and try each one until you find the best one, then return the unused ones

To select belts by size or part number.
http://outdoorpowerinfo.com/belts/
Select show/hide belts pick list
Select -T for Toro
Select- Toro
Look for the belt part number (if you know it)
Next to the part number will be a size such as Toro belt number 110376 is a 1/2"x38.5"belt or 4L385.
-OR-
You can use this calculator. Remember to add about a 1/2" inch? to the measurement if you need the belt to be slack, such as on an auger drive.
http://www.calculatoredge.com/mech/vbelt%20length.htm
You can go to Toro's web site and download the parts list for your model which will show the Toro belt numbers.

You can put the 3" adaptor on it for more stability. If you stick with the double stock pulley in the picture you can get away with a shorter one. You can get a 3" long one on ebay. If you decide to use different pulley set up and it is too long you can always grind a bit off or cut it down.


This comes with a stepped key that fits the 3/16 key in the Predator and steps up to 1/4" for the 1 inch bore pulley. Your pulley would need a 1/4" key for it to work as intended.

You may also want to put an appropriate length bolt and washer on the end of the PTO shaft. On the predator it is a 5/16-24 UNF thread.

IT IS best to do it under load.

I bought my first impeller mod from Clarence. It cost $30 + $10 shipping. I just did a second one and it cost me $18 for 5 feet of belt and then I paid like $2 for a big bag of nuts, bolts and washers. I ended up cutting out a metal plate to put on the top from an old piece of sheet metal I had. The dip in the Ariens impeller was pulling the rubber down with the washers so I had to make a bigger spacer. I also have most of the belt, nuts bolts and washers left.

I bought some rubber paddles for a Toro S-200 off eBay for $20 with free shipping. They are nice and thick so they should last awhile. I cut them to the lengths I needed and bolted them onto the impellers of the Toro 826 and my 42" John Deere blower and they worked awesome.

Bailer belt works great you can get it from Tractor supply or Mills fleet or any other place that sells farm equipment. My entire kit only costed $5.00 It only took a foot of bailer belt and bolts and fender washers and lock nuts to make the kit.
