Oh, XSessively wise GURU's, I have a question....

[eroellig]

After mounting my front wheel, I found it was draging instead of spining free. The problem is that the right brake rotor is scrubbing the outside of its fork slot. The left rotor is perfectly centered in its slot.

WTF?????

What did I do wrong???? I've reviewed the exploded parts diagram and I'll swear that all the parts are there. Both wheel bearings have been replaced. Both replacement bearings were identical. This condition did not exist when I tore it apart.

This is the only thing keeping me from having rolling stock (as in I would be able to push it across the garage).

Rear wheel spins free (even with the rear brake caliper in place.)

fix it

release the pressure on all attachment points.......

install the fender
torque those bolts first
aligns easier in this order.....
then tighten everything else.....

sometimes you get a little crooked

works when I do the front tire replacement everytime.

Ok. I'll tear it apart & try again. But, FWIW, I had the fender on first.

Hey Eric,

After you torque up the large castle axle nut, you then use a screwdriver or such to push the right lower slider outwards away from the tire to center the rotor within the rotorslot in the slider, THEN you tighten the axle Pinch bolt to hold the slider in that position around the axle. The axle has a shoulder on it that allows you to torque the large nut without relying on it's position in the right slider!

If you go to the tech tips from the MAIN FORUM PAGE, and look up maintainance, you'll see a new pictorial on tire changing, and it also has photos of this technique for your special!

This Guru has spoken!

OH!!!! That makes sense. The rotor looked like it was parallel to the fork slot, so I didn't think anything was crooked. That's why I was scratching my head. Clymers doesn't say diddly squat about re-assembly.

That was it. I HAVE ROLLING STOCK!!!!

I'm so EXcited!

Thanks TC!

Now I can put "bleeding brakes" on the active To-Do list. I think I may be able to start tuning up the engine next weekend (but I do have to take down a tree next weekend as well. )

I think I figured out how I got into this predicament. I had started to tighten the castle nut first, but the axle started spinning. So I tightened the pinch bolt to hold it still while I torqued the castle nut down. Never thought about the fork being able to slide on the end of the axle to center the rotor.

There are instructions in the Clymers manual. In my book it's in chapter 8, page 194, paragraph #6. It says:
"On Special models, tighten the axle nut to 76 ft.lbs (103 N*m) and install new cotter pin. Move the front forks up and down several times. Move the right hand fork sideways until the left hand disc (that must be a typo, it should read right hand disc) is centered within the caliper assembly. (Figure 13), Tighten the axle pinch bolt to 14.5 ft.-lbs.(20N*m)"

Well, there are a couple of mistakes I made here.

1) I was actually looking at Haynes, not Clymers. The Haynes book is the one that rather glibely skips overy re-assembly. In Clymer, it is as plain as day.

2) Having both books, I should have referenced the other one, like I have done for other things. Don't know why I didn't this time....

Thanks for pointing it out, John.
