So if it have been my bike, I’d be ordering a 50-pak of these from McMaster-Carr and sharing with mates. Hello-temp PTFE (500 levels max) with ID of 4.3mm and OD of 9mm, thickness from .7 to .9mm. Since they’re PTFE, if they appear cosy on the pins a lightweight contact with a reamer or handheld multi-flute drill bit will dimension them to suit.
$9.70 for 50 washers. There are different choices as nicely in these hyperlinks in submit#10.However, that’s simply me.
Greatest,
DeVern
Spot on – thanks DeVern for parsing the McMaster catalog for me. 500 diploma F max temp score must suffice! And hopefully simply slippery sufficient. Will report again, and if anybody desires to DM me an tackle completely happy to share the stash.
> On the topic: any lube suggestions for the pivots and/or heels/sockets of the advance unit? I’ve a lifetime provide bottle of “lubricam” for the rubbing block/cam interface already.
I’m inclined to make use of some trusted gentle Phil Wooden bicycle bearing grease until there’s a greater suggestion.
> Additionally as regards to advance models: when a washer disintegrated whereas servicing this advance unit off a good friend’s 76 r90/6, I swapped out for a spare advance unit I received used off eBay as a part of a backup factors elements group (was on a visit on a pair airheads working Dyna III ignitions, wished a backup in case of failure).
Solely later whereas researching rebuild elements did I discover on the market are completely different variations of the advance models.
In accordance with EME that sells the alternative springs, advance models with BMW P/N ending in 012 are for r90s and require a selected Bosch “heavy responsibility” spring.
Apparently models with PNs ending in “005, 007, 010” are for all different airheads, 69-78.

*by the way, the Advance unit that got here off this 90/6 is marked 012, and the spare I had that I’ve been utilizing on the 90/6 quickly is marked (the right spec?) 005.
My query: is there an precise perceptible distinction between the alleged 90s spec and the opposite choice?
I’ll swap this 012 unit again on after it’s rebuilt. And see for myself. Simply curious if anybody is aware of there to be a lot of a distinction.
> unrelated/associated, DeVern I see you’re in Utah. I’ve received household in Ogden – nice using out that manner. Did you occur to know the late nice Jerry Holcombe? He was in Layton if I recall. Helped me out on a street journey 20 years in the past and gave me a tour of his deep assortment of BMWs.
Thx once more
