371 Repower Project and Belt Question

[sbanks]

Hello all. I recently acquired a 371 project and am pulling out the Wisconsin and putting in a Predator 670 22hp. The Wisconsin drive shaft is much larger (I think 1 3/8") vs the Predator (1") and so I need new pulleys. In order to purchase the new pulleys I need to know the V belt sizes and unfortunately the 371 came without either of the belts. So, I'm needing to know what the belt sizes are supposed to be. One runs the hydraulic pump and the other is for the primary drive. The length isn't important since it looks like the new belts will need to be a bit longer than the originals since the engine will sit a little further back, but the belt width and depth measurements are important. If anyone has part numbers I can look up the specs. Thanks.

You should be able to work out what style belt it is by measuring the V, there will be specs on the net to tell you what width it is. Length, without the specs, you can use a piece of rope when the motor is is place to measure how long it needs to be.

The OEM numbers are:

6500720 variable speed drive

6500959 hydraulic pump

My big book of belt cross reference doesn't have the variable, don't know why some bobcat part numbers are omitted.
You can google the oem numbers and get the widths and cross sections, the drive belt is about 5/8" wide vs. 7/16" for the smaller one.
