Transmission countershaft 25mm lock washer fitment
Dolomite_:
Im rebuilding the transmission and cant quite figure out who the 25mm lock washer goes on. Its part 90462-323-000 and seen here on yamiya https://www.yamiya750.com/index.php?main_page=product_info&cPath=179_273_206_210&products_id=2860.
Is it meant to sit flush with the thrust washer? The outward splines wont fit underneath the splines on the thrust washer. I just want to double check that it seems correct before I put it all together.
I didn't do the rule of you never have enough pictures...
McCabe-Thiele (Ted):
It was more than two years ago now but I do remember trying to fit mine and it just did not want to fit flat so as to speak.
IIRC I took it off and put it back on again and it suddenly decided to fit after at least 6 or 8 attempts that seemed identical.
I might still have my old disassembly photos in my archive - I will take a look and post it if I find it.

Unless it is meant to fit with the bent splines facing away. Like this:
McCabe-Thiele (Ted):
I'm pretty sure mine fitted with the bent bits opposite to your photo so they located into the gear.
When you have the two parts in your hand so they fit in place together that's how they sit against the gear.
I could be wrong it was closer to 3 years ago but I remember having your problem. Not sure if they become distorted so you have to fit them in the same position they were in before you took it apart.
Looking at my downloaded parts book its with the tangs in against the gear with the flat part in the middle as you would expect.
I uploaded this photo when I was having your issue so it might be in my 400 project I will take a look.

Hmm, so the washer washer with the bent splines then the flash washer?
In the parts list it shows as the flat washer in between the gear and washer with the bent splines. There is no way the bent splines fit under the flash washer even trying to fit them together not on the shaft doesn't work.
Edit, reading through my haynes manual again, it does mention that the splines go inwards into the washer but I don't see how it fits. I think the diagram is also wrong. Its not showing the correct washers or gears.
