Do the tapered steering kits replace the bearing races?

Post by thekernal » Sat Sep 22, 2012 11:28 pm

Working on rebuilding a basket case, and I can't seem to find either the lower or upper fork stem bearing races (parts 53211-268-305 and 53212-250-305). In searching through the message board, it looks like people have been using tapered bearing kits when rebuilding the steering- if I go through this route, would I still need to order the races, or would a kit like this replace them?

No the taper-roller kits come complete as the outer and inner races must match the shape of the rollers.

Awesome- thanks. Did you have to use any of the supplied spacers?

I believe that you will need spaces as the bearings are different depth than the originals.

Anybody know if the CA77 Dream can use the same All-Balls kit? The Bottom race is the same part number but the top cone race has a different one than the CB.

dreams are a different size. all balls does not have a kit that fits the dreams. If there is another source for a tapered bearing that fits the dreams, I would like to hear about it as well.

Thank you Randy..

Well all right then. I guess I'll need to rebuild the bearings with what's available. Can anyone tell me--if I have a flat spot in the straight ahead direction at 8300 miles on an early '64 Dream, would that tend to be the races having divots being worn into them, or the balls getting flat spots, or both? I'd like to order parts before I disassemble. If the balls are hard enough that they don't wear, but dig into the races, then I can keep the balls and replace the races. I imagine if the balls got flat spots on them, I'd feel a "detent" at some other places in the steering arc as well, but it's only at the straight ahead point that the detent exists, which suggests to me that the balls are harder than the races and have worn divots into the races. Hmmm.
