Hey all,
I'm currently building a 70 XLCH chopper, I imported the bike into Australia from the US in parts. I bought it already as a hardtail, it's an earlier short frame with an unknown weld on hardtail.
I'm trying to get the rear wheel set up and brake working correctly, chain aligned before i tear down for paint to make sure everything is hunky dory. Encountering a few issues. My rear axle setup goes like this, Axle slots through left side axle plate, then through axle adjustment collar, through the left side spacer, through the hub/drum, then through the backing plate on the right side, then through the right side axle adjuster collar through right axle plate, then through a top-hat washer with 2 flats to locate in the axle slot and finally the nut. As far as i can tell this is a standard setup on any of these hardtails, it's a tight fit getting it all in but fits ok when its snugged down.
The brake stay/pivot point has a top hat spacer, the flat side sits flush up against the backing plate and the smaller diameter slots into the slot for the brake stay on the frame. My understanding is that a bolt is supposed to slip through the top hat spacer and into the thread for the brake stay pivot holding it tight in place. This particular frame has a step in the brake stay on the frame that doesn't allow enough clearance to tighten the pivot bolt up. I'm not sure if this bolt is supposed to be tightened down against the frame or if its free to move back and forth in the slot for chain adjustment. If i install the pivot bolt through the spacer and tighten it down against the backing plate before putting the backing plate in the frame the flats in the bolt will sit nicely in the slot in the frame but i'm not sure if it should actually be anchored to the frame or not. I am aware that there was 2 styles of pivot on these sporties, one where you needed to loosen the pivot bolt to adjust chain and the other was free to move. Not sure what i'm missing from my setup but something is off. Also, the top hat spacer for the pivot seems to cock the backing plate causing an uneven gap at the opposing end of the plate. I decided to reduce the thickness of the spacer a little so that the backing plate could sit straight but seems like there must be some other issue at hand if that was required.
Long winded explanation but to sum it up, i'm wondering if anyone knows what setup i should have for this pivot bolt in this frame, and maybe what could be causing the backing plate to sit unevenly in the drum. Also if it sounds like I am missing anything from my axle setup.
A few pictures might help explain.
Cheers
