CVT rebuild belt recommendation

Folks,
I am rebuilding my cvt trans after the belt blew up. I pulled it down today and thank the lord, no damage to anything but the belt. No broken gear teeth or damaged casing. So the big thing I need to replace is the belt. Any recommendations on where to buy it. I'm n the U.S. Virginia. Thanks

You will need to clean the valve body, as it will have ingested, some of the debris, or you will be taking it apart again.

I just rebuilt mine and am having issues if anyone can help. I replaced the belt, differential, idler, and replaced filter/fluid. After starting the car and placing into gear nothing happened. Not sure what to do at this point and if anyone has any suggestions that would be great. Thank you.

Thanks. I blew high pressure air through it all, then shot transmission fluid through it. Thanks for that info.

I have pulled the transmission down. No damage to any of the gears. I got the belt in and put the transmission back together. I just got the new flywheel bolts in, so I will mate the transmission to the engine on Friday. I noticed that the lower engine mount is missing so I have to hit the junkyard and see if I can find one. I was also waiting on the automatic shifter. Since the guy I purchased it from was swapping out the automatic for a six speed, i didnt have the correct shifter.
Anyhow, once I get the lower mount, I shoudl be able to put it all back together. I am working on another R50 that I purchased at the same time. That one is a 5 speed manual with a spun rod bearing. I will drop the engine on that on Thursday to do a lower end rebuild with a new crankshaft.
