Need bolt thread info R11RT

[flhfxd]

The two bolts, furthest aft, that hold down the luggage rack......I just removed and sold an aftermarket top box and I forgot to check the thread pitch on the bolts that were removed and sold with the unit. They are the two recessed bolts. I cannot see from Max microfische. Anybody happen to know this, or is it just trial and error? TY.

I looked at that fiche but I don't think those are the bolts I'm looking for. That appears to be the four recessed bolts on the forward part of that rack. The two aft bolts don't appear on that schematic. I'll just prolly eyeball it......I'm sure I've got something kicking around. Thx.

Item #10 looks right to me too, unless we need a better description of what's different with yours....?
If your after-market box was a Givi, that may have used longer ones of the same thread for their adapter baseplate.

Yes. It was a Givi. And the bolts were longer. So maybe it is #10 in the schematic? There's 4 shorter bolts installed in-line across the front of the rack that attach the rack to the side case brackets and then the two that secure the rear rack to the frame (down through a post / rubber grommet) into the rear frame. Those are the ones I have to replace.

You could ride the bike to your favorite store that carries metric bolts. Sweet talk the manager into taking a handful of bolts outside and try them until you find the right threads.

Just looked at the fiche again and bolts #10 show 4x installed which means they're the shorter ones that attach the front of the luggage rack to the top ends of the side brackets. So I don't see the bolts is question on that slide. Not a big deal. I'll just go get something that fits. Thought someone might have a quick answer. Thx

I just looked at the ones on my '98 R1100RT. The two aft are longer M6s, so it's probably M6 x 35. The 4 forward are shorter but also M6s - likely the 25s. I think the fiche is incorrect. They are all fillister head screws. Last time I was buying something similar, I found a nice selection at Home Depot or Lowe's.

Thx. I'll hit the local nuts n bolts store.
