75/5 front axle spacer identification

[henzilla]

Still moving, another long story, putting Smurfette,the 75/5, together enough to roll into trailer. Had front wheel axle in forks and nut/washer. Guess I set spacer elsewhere and found this in general area.
Haven’t tried to wiggle in place as I am limited left hand use, part of moving story, so a challenge this morning

Another approach

Can somebody show me a picture of the front axle spacer on a /5?
NLA and fiche drawing little help.

I found one on table in first post ( it looks way newer than what I expected on this model), the threads go thru but shaft not to install washer and nut. It does seem to be correct width

I am trying with one good hand and wiggling spacer trying to tap axle in place is maddening. Needing to get off lift and in trailer.

Steve -

I had trouble even finding the images of the proper spacer in the online fiche. I was thinking that maybe something from a late model R69US with similar forks would be useful but still can't find the part or any other info. Don't know if you're looked at Brook's refurb on an R75/5:

If I had the other bikes here, I could look at them

Couldn’t see enough detail in either links. If nothing else, tighten pinch bolt, flag tape on fork and axle and deal with it at new place.
I checked around table again but three Tupperware containers with rest of bike bits already loaded and I’m not feeling like searching before I leave.
Thanks guys

What material is it?

It looks like aluminum, if it is it may be a fork spring spacer. I will look at both my /5's tomorrow and get an idea of what it looks like and see if I can dig one up from my mountain of spares for a comparison.

Thanks, def aluminum and only one. I would expect same era patina as axle,nut, and washer

Steve -

Not sure what you mean by patina. I doubt there are any witness marks on the spacer. It should just sit between the top hat on the bearing and the inside of the fork leg. Here's what the spacer looks like on the disk (left) side of my /7.

Saying same look overall, old weathered in road use!

That’s the spacer, the aluminum one I found on table is 15mm and I think gap is 13.
The one I have looks like a Hexhead era part

Ran across this on Hucky's BMW page:

https://www.bmwhucky.com/007536u.html

Listed under part number 34 11 1 233 020u with dimensions 14.3x22x17.7mm. I think the 14.3mm is the axle diameter...22 has to be the length so 17.7 is the OD??
