Anyone out there have a '35-'36 star hub and rear axle with correct sleeve, spacers and spacer nut for a 45? I'm trying to research the parts and assembly. Not looking to buy, just doing research.

I have a '37 that's together and should be the same other than there is no speedo drive on the earlier drum.
What are we doing?

I believe a few of the parts were '35/'36 only and may have changed in '37 but I'll look into it tonight and let you know which ones.
I'm working on a manual for the early ('29-'36) 45's and just trying to fill in a few blanks (photos, dimensions, assembly diagrams).
Any help is greatly appreciated and of course photo credits are standard protocol.

Did some cursory research and for drum brakes, everything from 35-37 is the same excepting the drum, already mentioned.
The one piece spacer came out during the '38 production run although it could have been applied with the new 37 models.
(2 piece for a speedo drive unit driving from the star cover and replacing the shorter of the 2 spacers.)
Now I need to go to the garage and see if in fact I have the proper 2 piece spacers.

You betcha, although installed wrong, they are there.
I haven't decided that I'll restore this monster yet and to get accurate OD dimensions will required removing the crud!!!
I'm resistant to that but will try to assist as needed.
Going racing this weekend so let me know what you want and I'll see what I can do next week.
The bike is "buried" but needs to be moved up as it had the wrong motor and tranny when purchased and I've picked up most of what I need to get it back roadworthy.

The parts in question are:
#4001-35 Axle spacer ('35-'52)
#4004-35 Axle sleeve ('35-'40)
#4005-35 Axle sleeve nut ('35-'52)
$4008-35 Axle short spacer, right side ('35-early '38)

I assume the axle sleeve fits inside roller bearing sleeve #3963-35, but not sure of orientation or where axle spacer #4001-35 goes, etc.
I've scanned the parts book hub and axle diagram and I'm trying to modify it to be correct, but not all parts are shown.

Steve, I really appreciate the help.
Rudy, long time brother..... I'll be in Milwaukee this summer for a weekend and would really enjoy getting together.

I'm home early and pretty stiff this AM (your conclusions are correct), took a pretty good tumble yesterday. Not the flathead and it ran and felt great all day.
I'll pull the axle and see what we have one evening this week.
