Centering the rear wheel.

[SimpleMan_Omen]

I have put the rear wheel back on. I got it together and adjusted enough that there was proper tension on the belt and the wheel was spinning parallel to the belt then noticed that it was scrubbing on the right side inside the fender (against a screw).

Looking at it I'm not sure how to get the rear wheel centered in the fender.


You can see here that it is shifted a little to the right.


Plenty of gap on the left side between fender and tire.


Very close on this side and touching further in where the picture doesn't show.


Right side of the bike. Small spacer inside with the lip against the bearing and the medium spacer outside between the frame and rear brake bracket.


Left side. Large spacer installed with lip against the bearing.

The bike is a 2003 Pitbull. If anyone has an idea let me know. Or if you have a 2003 Pitbull I would love to have pictures of yours.

That's weird Aaron, what tire was on the bike before? Same size? Same brand? I know my shinko is just a little wider than the Avon I had before, other than that what else could be different? Spacers are only gonna effect the brake location unless you totally fuk'd up and put the left on the right, which would not really even be possible, is there any way to shorten those bolts? They do look a little long, hopefully someone can offer some better help.

Was it centered before you took it off. I would swap the two long spacers. Its not the tire and that's the only thing you changed. I would look at the spacer placement.

The new tire is an Avon and the old one was a Dunlop E3.

The screws in the picture aren't touching. It's the screws that go into the chrome piece that the fender and signals bolt on to.

I can't swap the inner spacer with the other side because then the caliper wouldn't line up with the disk. If it tried to swap the outer spacer then if would be pushing brake caliper bracket off of its slide that is on the frame.

Two of the spacers have a protrusion than that goes toward the bearings on both sides. Swap those two from right to left and see if that fixes it. What are you using to align the wheel.

They won't swap. The one on the left is rather thick and the one on the right is thin. If I swapped them then the brake caliper wouldn't line up with the disk.
So far I have only aligned it so that the tire stays the same distance from the belt the whole revolution as it spins.

Once you have the belt close to correct tension, you need to match the distances from the center of the axle. On a softail it goes to the center of the swing arm bolts. Someone here can weigh in on where to measure from on the hardtail. This needs to be exact. Use a metal shirt hanger or tape measure and get it exact. Then adjust the belt tension by turning the allen screws the same amount. Then blue Loctite the outer set allens.

The Pitbull is a rigid so there are no swing arm bolts. I followed the directions called for in the manual.

The manual states the following:

2002-2003 Models

On the 2002 and 2003 PitBull, measure the distance from the front of the axle plate slot to the axle. Make these measurements equal from left to right. Again, be sure to set belt tension in the process.

I put it back together, set the belt tension and aligned the wheel. After following the manual's directions I then used the stem of my calipers like a concentricity gauge while my daughter spun the tire and it spun true. So I loosed the rear fender screws and adjusted that to sit evenly over the rear tire. Now everything looks good.

Nice job. You also need some Dyna Beads so you can get those lead weights off your wheels.

Are you on the Georgia coast? Your pulley looks like it lives in salt air.

I'm closer to the mountains but I have only has this bike for a little bit. It has changed hands at least three times this year and I've been spending all my times since I join the group April 14th playing catch up maintenance.

I've looked at the beads and have read and heard all kinds of things online about them. How has your experience been?

I think they work flawlessly. The great thing about them is they dynamically adapt to the tire as it wears. Each time the tire spins up the beads find the light spots and balance the tire. I have hit 110 with no wobble. And the wheels just look better without the lead weights. Just make sure you use enough. Curtis can tell you what you need for your Pitbull's tires. My tire shop got it wrong and it was noticeable.

Is the chart for the beads? What does the right hand column represent?

 

[pknowles]

Ounces per tire??

Yes its for the beads, the column to the right is the number of oz

Thank you. Silly me was thrown off by capital OZ. Everyone seems to like them so I guess I'll give it a shot.

I got a 180 tire and put 1 ounce for now. There’s actually instructions in mine which state to add x amount per tire weight. Tofu king bad that I had it on the rim already when I saw it. But it seems to run fine with 1 so far.
