Crossbones wheel/dyna hub alignment
So ive got a 2012 Wide glide that i found a smoking deal on a cross bones wheel for. Figured that i would have it laced to my WG hub and not have to worry about alignment/spacer issues.
While i was at it also sealed the inside with an Outex tubless kit. so i got everything ready to slap together this weekend...stuffed the tire and wheel up under there. have a new avon cobra 200mm tire mounted on it.
Take a look at it and its sitting 1/4 off to the left side. i hooked the shocks back up...they are slammers so the tire is stuffed into the fender and removed the caliper mount. if i position the tire center in the fender
im pretty much exacty one groove off on my spacer on the brake side. (one groove to wide) not sure how that that this is..i havnt mic'd it but if u have looked at the grooves in the spacers....then you would know...
Also i looks like there should be enough play in the caliper mount, where it has the recessed area that slides over the frame tab to keep it from swinging.
im curious why on my bike with all the spacers in place, i had slop between the width of the swing arms and my hub. i could bring that in just turning the axle nut with my hand..but still i figured it would be
snug fit before hand.
soo....anyone have an idea why its not centered now?...maybe it never was and was just less noticeable...or the rim wasnt laced dead center..or?
Three day holiday weekend and now i cant do anything.....ugg

so looking at this some more, it appears that since the wheel has to move to the RH (brake) side that the brake caliper mount would have to be milled down rather than the spacer? other wise wont it mess up the alignment on the rotor?
seems to me the bracket would have to retain the same clearance where ever the rotor moves. but then there is the issue of...is there really enough clearance where the frame tab goes into the caliper mount bracket.

My guess is either you have the spacers wrong or the wheel is not true...did you true the rim yourself? If so was it zeroed out?
Also did you set the rim up prior to mounting the tire? Most builders I know. Myself included usually mock up the rims first, making sure the rims are true, fit is proper and no interference with rotor or pully (for rear)....

it was be better to center tire with in the fender itself.
the spacers are correct because the smaller spacer is on the RH side and that is the direction the wheel needs to go. as far as the pulley i did have to get a spacer to clear the tire.

[QUOTE=cggorman;17646766]It's not unusual for Dyna rears to be offset a bit. Mine was. Nemo's was, too, IIRC. We both fixed ours the hard way.[/QUOTE
that is interesting. I dont remember my wheel being offset before but im not sure how much i paid attention. i have a turn signal relocation bracket and run a removable backrest. this sets the wires for the turn signals back further, but i
did noticed that the cover for the wires had been chaffed. which seems it would have been pretty hard for my 180 stock rim set up to do...
is it possible to have the wheel true but offset to one side?
if your rears were offset....where they sitting to the left (belt) side to far ?

Yes, it is possible to lace an offset but it may require different spokes (shorter on one side, longer on the other) if you have to shift it much. FYI, there is an offset dimension in the service manual for the stock parts. I don't know if that number centers the rim or not. Mine is far from stock.
I don't remember which side mine was closer to. I know it had a bad habit of tearing out the right turn signal wires from tire chaffing...so probably to the right. Edit...oh, and that was with a dealer-installed MoCo mag wheel...before I started modding amd fixed the offset.

remove it from the outside of the of the caliper bracket...then it will bind the caliper on the rotor...i thought about the possibility shimming the caliper on the bracket but not sure how smart that is.
btw ....are the rear rails on a dyna just steel?.... they almost look cast just looking at them. (where the fender bolts on)

The fender struts are cast steel. Solid. Very heavy and strong.
Shifting the hub either way will affect the rotor/caliper alignment, but I believe you caliper is a floating unit so there should be a certain amount of adjustment available. I just don't know how much.
Unfortunately, my experience is two generations removed from yours. My 99 had the Evo-style single piston brakes. On mine, the entire caliper bracket could be shimmed in or out to maintain a position relative to the hub. (A thin shim between the bracket and swingarm.) Perhaps yours is the same?

Ive seen a couple posts about people bending the struts out, im surprised there is any flex to them though if they are cast still..i'd hate like hell snap/crack one. id imagine caliper can compensate a little but like you..i dont know how much. would be easier if i had a spacer to throw in there and find out before cutting mine down and finding it wont work. my caliper bracket sits directly against the wheel adjuster inside the swingarm...no shims or anything... so...hub bearing, spacer, caliper bracket and then swingarm. the caliper bracket has a recessed area in it that slides over a tab on the swingarm and that locates it it dont just swing in circles. its also part of the apprehension about milling down the outside of the bracket because i dont think there is much room left depth wise for that tab. other than grinding the tap down some.
