Title: rear wheel drag question.
Post by: chuck on July 18, 2010, 09:28:12 PM
When I tighten the axle nut on my Penton 125 the rear wheel does not rotate freely. The tigher the nut the more drag. I also have a Penton 100 that does not have this problem. Same set up on both bikes. Any ideas.

Thanks,

Did you change rear wheel bearings?? Did you put the center spacer back in correctly?? Are any and all other spacers replaced correctly??

Bearings and spacers are all correct. I swapped wheels from my 100cc with my 125. The 100 wheel spins fine on its frame but when you move it to the 125 and tighten the axle nut it drags. Also, when I move the 125 wheel over to the 100 it spins fine. Its as if the swingarm on the 125 is fatigued and when the nut is tightened down it binds the wheel.

Is the chain adjuster rubbing the sprocket carrier?

Doesn't appear to be.

Distance the same across both swingarms? Both swingarms parallel??

Chuck,
Switch the axles and see if your problem changes. I suspect you may have an incorrect axle.

Chuck,
  I agree with Randy and check to be sure your swingarm isn't bent and that you have the proper axle adjuster on the correct side.  I hope this helps.

I did swap sproket carriers. The only thing I didn't swap was the axle. I'll try that.

Thanks for all the quick responses.

ditto on "thrownchain" response.  The rear wheel chain adjuster has a spacer attached to it, and it must be oriented in the correct direction, that is, toward the sprocket hub bearing.  It amazes me how many of these are incorrectly installed.  It can cause a binding in the rear wheel assembly.  The brake backing plate must be spaced correctly, too.

Joe,

You're right. I had the chain adjustor on wrong. I don't know how many times I've had the wheel off and never noticed there was a difference. Dumb luck I always put it on correctly before. Obviously, a mechanic I am not.

Thanks,

Chuck
