This is only a question as to how would you determine belt sizes.
The reason I ask is because my kevlar belt had a lot of play in it when the drive face has enough centrifugal force to go into highest gear.
Somewhat noticeable during idle. The belt smacks the walls. I actually think I'm receiving a power loss over it.
I ordered an exact replacement and I'll see what happens as it might of stretched, but I really need to find out if there's another way to determine the belt size. I'm sure there's a chart or something.?.
But for now if there's a way I can measure from the variator to the clutch and convert it something idk ffs idk anyone might know lol!!

Long case, I think I can fit put a 13 inch wheel on "14 max".
The belt seems almost perfect except for the slack in it that could be caused by heat, I could be wrong

Yes, that's one of the first parts I checked. I was lazy and snapped a picture of the belt.
The wheels are 10 inch rims with 3.50 on the tire.
The belt is "723 17.5 28"
I haven't seen one with a wider width and or anything that would say racing.
I honestly think it might of just stretched to be honest, the sides have a waxy look and the outer edges have turned white.

What is the engine # ?
How many bolts attaching the cvt cover?
What size belt is the one giving you a problem?
It's ok to answer you not sure or "I don't know".

Sorry for the late reply, I had a lot going on during the time of the post and sadly forgot.
Engine model number is: JN1P39QMB
The belt the seller sent with the motor was a 723. Which apparently was the wrong belt, and ensured me there was no way he did that..
He says it's supposed to be a 729..
The bolt count is 9.
I can measure pulley to pulley if you'd like?
*If you are a vendor, there's a few things I would like to look into. Taller rims that are a little on the cheap side that as well tires won't be expensive to get. Future champion battery cover. I also had odd OEM mirrors that had red running lights. If I can get pictures to finally upload I will post those mirrors.

He tried help you several times and you wouldnt answer any of his questions, then you started another thread for the Same problem.I'm sure like the others has given up on trying to help you, He has a web site to click on or you can call him, but your done trying to fit taller 12" or 13" wheels on a Fiddy. That new Motor is shipped complete from China to them, they shelve it and sell it complete as it came to them, the add or subtract no parts in house. |
