Crank bearing shell sizes
« on: May 24, 2019, 04:30:23 PM »
Hello. Quick sanity check if I may (Oddjob, Julie, etc...)

I have a case with BBBAB on it, and my crank looks like this:
[ Guests cannot view attachments ] [ Guests cannot view attachments ]

I think I need 4 sets of green and one set of brown mains and four sets of green big end bearings.
B1, B1, B1, A2, B2
2B, 3A, 3A, 3A

That seem right?

Crikey they are some of the clearest numbers and letters ever. I never did find the numbers on my 350F no matter what I tried nor how hard I tried.
Current bikes:
TriBsa CCM 350 Twin
Honda CB350F in Candy Bacchus Olive
Honda CB750F2 in Candy Apple Red
Triumph Trident 660 in Black/White
Triumph T100C
Suzuki GS1000HC
Honda CB450K0 Black Bomber
Honda CB750K5 in Planet Blue Metallic (Current Project)

I think the camera flash had a lot to do with it. I was highly unsure about the number on its own until i looked at the pics.

I thought yours looked very clear but my 400/4 ones were quite easy to see also. But maybe a flash photo is the answer. But, it's the very early 750/4 ones that are scribed in Japanese I can't see and then when I do manage to pick them out, there is a 'translation bulletin'......my brain doesn't recognise Japanese script at all, so its real fun and games.

Yep, I was looking at it first as a whole picture and thought the crank was broken  ;D

So next question then; is David Silver the only supplier? My Japanese isn't good, so i fear the answer is yes.
