my bike came with mismatched wheels, being an early kick start N model I concluded the front was wrong. Rear has short slots, it all silver with no plastic inserts.
The front has long slots in the spokes, and the spokes are a metallic grey colour.
So I now have a wheel matching the front, all seemed fine until I take them apart.
The discs on my bike are bolted as per manual, the spindle has a nut and pin on the left side.
The correct looking wheel has discs held on with through bolts (discs are same) a different centre hub with different holes in it when the discs are removed and a totally different spindle which has no nut on left but an unscrewing barrel from the right with a different spacer/oil seal on bearing.
Is this spindle/disc fitting arrangement a later bike CB400?
I have messed up, I wish to use the wheel from one and the hub from the other!! the disc spacing is wrong on the wheel that looks correct using that hub. I do not think I can remove the hub though?

Generally you have,
The N & NA with the MT 1.85 tubed rims (1978-1981).19" front 18" rear.
5 x UBS bolts securing the discs or cover each side of the tapped hub.
The 400NB-Early ND / CB250NDB-CB250NC with reverse comstars, tubeless MT2.15 rims, same diameters, through bolted disc securing. (1981-1083 M/F)
1984 up, mostly europ, Australia & NZ, CB400ND & CB250NDD, Boomerang plate spokes with circular lightening holes, 18" front, 18" rear, tubeless MT 2.15 rims, discs bolted through.
Spindles all the same on all the models as the fork cases externally are all similar geometry at the spindle position. Tightens to the left leg, with washer nut and cotter pin.then clamped at the right.
Pictures may help.....

ok, something not right then, the wheel I have was said to be off a CB400N, BUT wrong spindle so is either a bitsa or off another model. I will post some pictures, but is there a way to remove the hub from one t the other?

    picture of style of wheel on the bike to rear. on bottom pic plus top pic is its markings....400n kick start in red with fat blue stripe. Also the more grey front wheel with long slots that was on it is 3rd picture...want to replace.. Then also the silver wheel, twin disc that looked like the rear one, and is the same (but tubeless it says) . However wrong hub/spindle. |

My 400n, red,       
Are your fork cases the same as this? Got a magnet? are the front wheel spokes magnetic? If a 19" wheel, could it be off a 1977-78 750?? but they tended to be 35mm for diameter and 182mm spacing compared with the SD 33mm and 172mm spacing tube centre to centre... so don't know. Very early CX? but still MT 1.85 & tubed marked on the rimAre your forks generally same as mine? |

44610-443-611  could be the correct wheel if you frame number is = or less than -2008579, very early in the production run, may have the same steel spokes as the dream wheel?? (My red kicker is second half of the production run, I don't have anything earlier except perhaps a dream front wheel if it's sill in the storage).

my forks look correct and I am sure they are, its the rogue wheel I got to put on it is the issue. I think the wheel that was on the front is simply a later model, it has steel spokes, magnetic and slight rust. If the hub would change then the nice matching wheel would be perfect haha!
The rear wheel and correct looking front rim with wrong hub is ally, not magnetic.

You can’t take the hub out of the Comstar wheels - you may be out looking for another

why do you think its the wrong hub? am I missing something here? as far as I can recall the early superdream wheels (alloy rims,spokes and hubs) have 10 short front disc bolts for the 400 models and not the later through bolts

It is possible that the discs were swapped at some point and the through bolts fitted after drilling through the wheel and removing thread
Question are the nuts standard ones or lock ones - they will have metal stick outs in them

So it must be off something other than a 400n though was told thats what it came off! anyway....I need an early style front wheel. Will a 250 wheel be the same as a 400 and receive the twin discs. |

Yes it will, but not a CB400T dream or a 1981 CB250NB wheel although the left side is the same the right is not

I wonder if the rogue wheel I was supplied as CB400 but has differing hub/spindle is a CX500.

CX has the same spindle type I'm not sure that it is a rouge wheel just a rogue spindly if the distance, disc mounting to disc mounting surface is the same as the SD if it is 10mm more CB650/750 1978ish perhaps. (and can't see tubeless on the rim...)  |

perhaps 650/750 then.....the 2 discs mount a little wider than the superdream on the hub. Its no good for me haha!
