75 MK3 correct assembly of parts for axles

75 MK3 (7-75 333947) Looking for the correct assembly of parts for front and rear wheel

Does anyone have or know where to get a correct part layout or have pictures of the front and rear wheels for the spacers, washers, felt seals, nuts, and such for the axles. I have mixed up the parts and or misplaced them and the parts books do not show or give enough info to sort this out, and I have found them to wrong at times and now I don’t trust them.

For example: The rear wheel spindle is shown in Clymer, Haynes, Old Brits, and Andover Norton as being threaded on both ends but mine is threaded only on the one end that goes into the dummy axle, the other end is a hex head 15/16” .

The Clymer service book shows that front wheel, page 142, should have a spacer # 7. My bike never had this spacer as I am the original owner.

I am just trying to get the front and rear wheels back on the bike correctly and wish I would have taken more pictures when I took it apart.

Thanks for any help you can give.

The factory 850 MkIII manual contains diagrams which show the correct sequence of assembly, but without the part numbers.

Yes, every MkIII rear wheel parts diagram I know of, is wrong, including the one at Andover Norton!

However I think the front wheel diagram at AN is correct? http://www.nortonmotors.de/ANIL/Norton% ... &Plate=022

Here's a previous thread on the subject which you may find useful? post30561.html#p30561

I always get a chuckle out of those parts illustrations. There is no way mechanically possible to insert a threaded, shouldered axle into place as shown, with the sprocket sub-assembly and wheel installed. There is also no way to install it first, then install the rest of the stuff!

Les,

Thanks for your help.

I now have both the front and rear wheels back together and they look correct.

I can't believe the manuals can be so screwed up. I was getting very confussed and then the thread you pointed me to had pictures and that helped a lot along with you pointing out that the part manuals were wrong. BTW in that thread the washer was listed as 06-5459 (cylinder head steady bracket). I am missing the washer 06-5549 that goes on the outside of the speedometer gearbox but I think it was like that for a long time but I will try to find or make a replacement.

Thanks again

Thanks, Chuck. I have edited all references in that thread to include the correct part number.

As you probably read in the other thread and saw in the photo neither has mine, as it needed an extra washer between the spacer and the bearing to prevent the drive gearbox from rubbing against the sprocket.
