Hello, friends.
I have a question about 50cc scooter transmissions. I have had multiple exhaust failures, and now belts are breaking in about 30 miles. I took the CVT cover off while it was running, and the shafts that the clutch rides on is not true. It wobbles, causing the clutch to wobble. That is causing belts to snap, and the vibration is causing the exhaust to crack.

What is that shaft called? Do I just replace it? Is there bearings I have to replace? I have replaced virtually everything on a scooter before, including a crankshaft, except any gears. Will I be able to do this?

Thanks.

Thanks. You are saying that it is the rear wheel axle bearings?

Do I need to replace the final drive shaft, and those bearings, plus the clutch shaft?

I normally get stuff on ebay, but I don't know what bearings to get, or what they are called. Are they hard to get out? Do I need a puller?

You'll see immediately if anything is loose or broken.
