I have some slx cranks I am going to sell but I’ve lost the washer that goes on the none drive side.
Part (A) on this image

What is its shimano name and where can I get one?
Thx

Doubt madison will stock that spare.. Try a 24mm ID rubber o-ring?

part number should be on one of the other shimano tech PDF’s

Lost my one years ago, is it actually important?

Bit more digging around found it.

I found mine on the garage floor after I changed my BB.

Will I die? 😯

Eventually, yes.

oops – just checked all my hollowtech cranks after seeing this – out of the 3 sets on my bikes none of them have this part intact (all bought used) 😯 – so I guess I’m doomed!

DOOMED DOOMED YOUR ALL DOOMED 😈 😈 😈

But… What does it dooooooo!

I just got some new Deores that had one.

What does it do?

Have you sold them yet? Email in profile if not, may be interested! And the missing part is no problem 😀

Isn’t it just an o-ring there?

It’s apparently to stop water going inside the Bb.
I can’t confirm that, it’s from a Google.

Yup stops water n shit

I dropped one of those on the garage floor last week, took ages to find ! Was replacing a 10 month old XT BB on my shop build Soul. Embarrassingly I have ridden it since last spring and not noticed how, going by the spacers on the BB, it is quite unique, with a 70.5mm shell width…good ole bike shops eh 😈
