Thanks for
Your feedback!

Hi Guys... Thanks for your inputs!

I have thoroughly cleaned the Crankshaft with BP's finest and can't find any markings on the Crankshaft! I know where they should go as DS sent me a picture of a new one!!

I will try and post here some pictures but failed last time i think due to the size of iPhone pictures.

The only clear marking I have on the crankshaft is a N or a Z next to No 1 Big end!! (Depending where you look at it!)

Is it possible that they are all the same size therefore and maybe originally should have been all Yellow?

If pictures do not upload if you PM me then your email address then I cold send you them via Email!!!

Much appreciated with your input this is driving me mad!!!

Hi guys

Would really appreciate your assistance on this one!!

Recently broken engine down and sent away to Engineers as I thought i'd get the tolerances checked by a reputable professional!!

Unfortunately, they don't know and I forgot to advise them of the various different size shells and they weren't ever aware!! Anyway they removed and bagged them all up but have advised the the bottom end was fine and nothing needed changing but advised just to replace standard size shells!! Thats when panic set in and I had realised what they had done!!

On checking the Crankcase it is coded AAAAA. However, I cannot read the codes from the crankshaft so do not know exactly what colour shells are required for what journal!! Having spoke with David Silver they advise with AAAAA it can only be either Yellow or Green but don't have any Yellow in Stock!!

I was just considering whether to take pot luck and replace existing shells but don't know which came from where!!! Alternatively try using Plastigauge and trial and error. All the shells look exactly the same and there is no colouring on them and the engineer could not advise of different sizing!!

Could it be just possible that as its AAAAA they also happened to use the same Shells?? The engineer tried to measure but as we all know the tolerances are so fine... Fortunately he kept the big-ends in situ with the con-reads so happy there!!!

Any suggestions gratefully received!!!

Paulbaker no worries!! I’m referring to my CB500 my CBR is injection!!!

I’m a MAC/iPhone user I gave up on windows years ago ! Does that have an impact on uploading pics??

Cheers
