ya so whatever u call that thing that the belt goes over at the rear tire has some pretty substantial play.
 normal? or time for new bearings?

Thanx Serowbot

Normal, but not good. When the bike's new, the pulley's kept running straight by being squashed up against the cush drive rubbers between it and the hub. Once they wear it flops around a lot. You could live with it, replace the rubbers, or fit a wider double row bearing and turn down the spacer to suit (must be a fully sealed bearing 'cos you'd be ditching the standard separate seal).

You'd be looking for bearing with internal diameter 25mm, external 62mm, and thickness 24-26mm. E.g. NSK 5305DDU.

or, as i posted in another thread, slices of inner tube.

"there are rubber triangles built into the hub to absorb power pulses & clutch engagement shock. they arent perfect. i sliced up an inner tube & shimmed them up. that decreased the amount of deflection the pulley goes thru under acceleration, decreasing belt wandering,m

contact cement is your friend,

pieces of inner tube cut too big, partially inserted on each of the long sides of the v shaped rubber will drag down into place when the v is pressed down, IF you smooth things up on the wheel 7 slime it with some glue.then trim to fit after its dried. i didnt mess with the outter edge, just the sides of the wedge.

this is a good time to decrrease brake shoe contact area so it doesnt lock up at the thot of using the rear brake".
   I got it JOG i just don't have any idea what yall are talking about. probably time for me to get a clymers. Being a broke artist sucks!
Dave, its not rotational slop, It's the bad slop.
  The only thing I can see or feel that is rubber next to the sprocket/pully is a rubber piece that seems to be in between the pully and the rear hub. Is there like a diagram somewhere on this site of the rear assembly? because y'all are given me key advice here, but since I've never been through it and can only see this nonsense from the outside I'm having a hard time understanding what yall are telling me.

oh sweet thnx

Yep, number 4 is the wear item in the cushioned drive hub. If you've damaged parts 15 or 16... somebody set your drive belt entirely too tight (and really overtightened the axle nut). And will likely have damaged at least the seal behind the front (drive) pulley (rear is the driven pulley). Fixable, but a major league migraine to deal with. The front seal, 15 and 16 aren't too hard to change out.

BTW. I also have the belt loosened a bit because i have the ryca cs1 kit on. ...or should I just torque it up a bit to maybe 60
