The parts list shows item 50 part 14501-323-000 Clip DS £9.48 each.
Mine look okay but is it something that must be replaced due to age - pricey for what they are?
Ive just bought 2 Ted, Mr silvers had £500 off me this week, I recon the overall cost will be £1000 for my engine build. I suppose that’s what you get when buying bikes that come in a box I’ve been pricing a few more bits up today. Generator cover 11632333010 £82.80. The best one has to be the bolt that goes above the cam chain adjuster bolt, no 177, 25911500000 £40. Im going to make 1 tomorrow out of stainless

I bought a set for a 400/4 not fitted them yet but they seem bang on for the money. Nurse Julie recommended them and uses them in their rebuilds so that was good enough for me. Mine came from the Cruzing Image eBay store, that way you do get buyer protection if they don’t turn up

If your figures are correct BTW, you'd need Brown, Brown, Brown, Green, Green. As all your figures are within the middle column and are thus No2.
Thanks for that, Ted came up with the same colours so I'm happy to go with that. Just need some overtime in now to pay for them

Where's that from Daz, my info came out of the official Honda parts book.
Well that's interesting, the workshop manual and the parts book show the same figures but in a completely different way. Seems Ted was right, I presumed it was a misprint as I've not seen Honda do that before, they tend to go up in sizes on the charts not down, so 1 would be 32.000 to 31.99 (who the hell writes figures like that) 2 would be 31.99 to 31.98 and 3 would be 31.98 to 31.97. Very odd and not something I've ever noticed before, the 500/550 shell bearing selection is far easier to understand.
I also have a Mitutoyo digital gauge and whilst it's good I don't think it's that good.
Its out of the 400 workshop manual in the Aladins cave download section http://info.sohc.co.uk/download/cb350f-cb400f-shop-manual/

Trouble is you need a REALLY good micrometer to measure them accurately. By good I mean professional engineers workshop good. Probably costing hundreds if not into the thousands I'd imagine.
I have a new mitutoyo digital micrometer that i used but ill get it checked tomorow at the engineers whos doing my rebore

I would suggest remeasuring as the smallest size listed by Honda for the crank journals is 32.000.
Ive checked them a dozen times

Have you tried heating it up with a hot air gun ? obviously don’t melt it but it brings all the mould oils to the surface and shines again, mine came out like new.

Thanks i'll have a look when i get home from work and see if i can work it out. Im no engineer and moneys tight so I cant afford to order the wrong bearings, I'm sure i'll get the hang of it in the end

So is it possible to get the bearing size without measuring the crankcase ? The cases are marked BBBAA
The main crank journals measurements are
No 1 – 31.986
No 2 - 31.986
No 3 – 31.987
No 4 – 31.988
N0 5 – 31.985

Did you find any markings on the shell edges ?
I had to do a bit of educated guesswork from the ones that were colour coded then try them in an unmarked conrod using Plastigauge to check the clearance.
My understanding is that you do not have to measure the crankcase as they are stamped with the codes.
No unfortunately, the crank had been removed from the engine by a previous owner years ago and the shells had been lost. Luckily the con rods were still attached but pistons had gone

You cant always find the crank markings, on my 350F (or it could have been the 750K4 memories eh) they simply had disappeared. I tried the petrol trick and used a very bright LED magnifying lamp but never did find them. If that's the case you will need to measure them very accurately with a calibrated micrometre (this is to tenths of thou's), if you cant do it go to a machine shop and get them to measure them for you. It's very important that you get the correct size shells.
I’ve tried but can’t read anything. I have treated myself to a new Mitutoyo digital micrometer and successfully measured the crankshaft journals but I have nothing to measure the crankcase with yet
