I broke off all 4 rear disk bolt tabs on the hub. Half of the holes exist but I imagine it would be impossible to build them back up with weld then drill and tap?
So my question is has anyone laced a rear wheel on here, is it possible without a truing stand and dishing tool. Maybe just mount it back up in the swingarm for truing.
Or for the cost difference of purchasing a hub and spokes I should just buy a whole new wheel.
Anyone have a used one for sale? Wheel or hub for a 2007 Sherco.
I'd probably get a new hub to be safe and it may even be cheaper in the long run. If you want to try it yourself,
just remember that it's a long, slow job to do it correctly the first time, but you'll learn a new skill in the process.
Truing can be done on the swingarm after the wheel is assembled although a truing stand makes it a lot easier.
If your rim is bent or warped, it will add a lot of extra work as you'll need to compensate during the truing process (if you can).
Check to see if the rim is "offset" or "centered" by looking at the wheel directly from the back of the bike and seeing if the
rim is to the left, right or center of the hub centerline. If it's offset, you'll need to measure how far to set the rim center out
from the hub center and on which side.
Most Trials models use centered rims and there will be two lengths of spokes. The longer spokes will go on the outside of the tabs on
the hub as they have to wrap around the outside of the tab. The shorter spokes will have their bend on the inside of the tab on the way
to the rim.
Spoke patterns for dirt bikes are almost always what's known as a "cross-four" pattern, which provides the best strength. If you look
at the wheel from the side, you'll see groups of two sets of crossed spokes close together. ie. "cross-four".
Buy a really good spoke wrench, as they are specially designed with a wide gripping surface that does not strip the nipple flats.
When you get to the final truing, you can tape a wire on the swingard to use as a wobble gauge. Sometimes a wide felt tip pen can
be held near the rim and will give a black band on the rim where the rim runs out and the center of the band is the area of greatest
run out. You'll want to give the nipple a few turns at the center of the band and a lesser number of turns proportionally to the nipples
going out from the center of the band. Wipe the pen mark off with a little solvent on a rag and repeat.
