Size of wheel shaft washers

Lost one of them rotating and balance wheels. How bad is it to ride missing one and which would be the best one to leave off?? Right now I made sure the rear motor wheels have one on each side of the wheel and am now missing the outer one on one of the front wheels. Do these little washer/spacers come when you order a new wheel bearing? Will try riding it tonight and see how much of a "screeching" noise I get.

 

Are you talking about the "speed rings"? if so its important to have the correct number in the rear but you can probably be minus one up front just don't crank down on the nut tight. Order some online they are super cheap.

 

Thanks. That's what I thought and it was one in back that was missing, so I robbed one from front. Ride was real smooth and I really noticed the difference in balancing wheels. Anyway did some research and order some speed rings online. Actually needed some more cause a couple of them are pretty worn and a little miss-shaped??? Will probably replace them all. You're right. They're real cheap, but apparently necessary to keep bearings from wearing.

 

Yeah that sounds correct, misshaped evolve speed rings is pretty common. FYI they shouldn't get worn out if everything is done up correctly.
