    Hi All
    Changed rear disc today, everything came apart easy enough but after resemble have found that once I tighten up the rear wheel main nut I cannot turn the wheel. It goes solid then as soon as I loosen nut again it frees off.
    Very odd caliper is not mounted so no drag from that, had it apart a few times , nothing appears to be missing and bearings are good.
    Any ideas ?

    What nut are you referring to as the "rear wheel main nut"? The 4 lug nuts, or have you converted to a single nut rear wheel?
    Or did you totally disassemble the whole rear drive hub and are referring to the main nut that holds the whole hub in place?
    What year VFR is this?

    If you removed the axle to install new disk, I would suggest you put something back to front or left something out.

    Oops, noticed it was the rear wheel brake disc. That would require removing the whole thing.
    My mistake. You really only have one choice: take it back apart and check everything against
    the Service Manual to make sure all is correct. Then reassemble.

    Had it apart a few times now and cant see anything wrong, going by the parts fishe online nothing is missing, I didn't check his much drag I had before removing the wheel in the first place but obviously couldn't have been as bad as now. It's on a 2000 Aniversary addition VFR pre V tec, just the single large nut. When its nipped up by hand everything is fine but as soon as I tighten further the problem begins.

    Do you have a copy of the Service Manual? There's one online here I believe. You've mentioned
    checking against a parts fiche, but sometimes that may not work as well. There could be an
    assembly procedure that isn't obvious, but is specifically mentioned in the Service Manual.

    Does this distance spacer wear over time, my only thought is that its not spacing off the sprocket carrier enough and when I tighten up the main nut its clamping the carrier to the outside of the bearing. Is there a minium thickness quoted anywhere for this spacer

    Hey All, Has anyone got any thoughts on this? I've got the exact problem. When i removed the stub axle nut it was just nipped up, to stop the rear wheel
    locking up. It can be locked on the shaft with top rim of the nut punched into a groove along the shaft. Changed the bearings but now have this problem
    Don't want to put it back and leave it like this. The recommended torque for the nut is 200nm. Any thoughts would be great. Cant make heads or tails of it.

    The only theory i have is that i replaced the bearings inside the housing (left side) with some from a bearing supplier, two of 6908rs 40x62x12 bearings.
    The two i replaced weren't original ones. but from a pic in the service manual one bearing looks slightly smaller in width. like one is 12mm and one is 10mm.
    by my measurement on the stub axle that two mm would allow the stub axle nut to be fully tightened. Only thing i cant find anywhere what the exact dimensions are of the genuine honda bearing. (part no 91061 mlo 731) . any help would be awesome

    I'm quite late to this but about the picture in post #13, it looks like you have replaced the original 5th gen rear brake disc which has the disc and the plate (parts 15 and 16 here https://www.bike-parts-honda.com/ho...FIX/Frame/REAR-WHEEL/13MBGW41/F__1600/2/10450) with an EBC MD1164 which is of the type and dimensions of the 6th gen disc and goes in without the plate (like part 17 here https://www.bike-parts-honda.com/ho...002/Frame/REAR-WHEEL/13MCW2E1/F__1700/2/10324) and still put the plate back in with the disc. I don't know whether this causes the problem you described but it might make the disc misaligned.
