CB750K7 Big End shell bearing identification

(1/5) > >>

ginger_jim:
Hi all, I cant see a number anywhere on the conrods to identify which bearing to buy.  Am I missing something?  Help!

Hi ginger Jim.
Mind went totally blank for ages I could not remember what to look for.Crank case not a problem then it came to mind the big end shell numbers are printed on the two halves of the conrods.When you put them together you will see a number 1 to 3 if I remember right.Sorry for the sketchy view but you will see what I mean.
Hope this helps

Oh dear, I thought you were going to say that!  It looks like there may have been a mark at some stage - looks like it was written in black marker pen but its impossible to make out for sure!

Looks like it might be a job for SEP http://www.sep-kegworth.co.uk/page1.htm

For sure it does look like a marker pen but for Christs sake I hope you dont have to look for the scribed number for the main bearings really hard big magnifying glass for this.I have done a few fours in my time 400 750 and to say conrod marks have been fine.I had a lot of trouble once trying to find out main bearings  and got in touch with an ex racing Honda man who told me with the sohc engines fit the biggest shells you can get and run it in gently and you will have no problems because of the age.I have to say I did not take that advice.We all learn something new every day so sorry leave it to you.
All the best
Bitsa

Aha! I spot an opportunity for me to learn something before I need it! I thought the big end shells were colour coded ( color coded for US spec ) and that the colour was on the outside of the shell? If they are numbered any chance of a pic from somone to show what to look for?

Could the numbers on the rods b to identify which cap goes with which rod? ( and perhaps which cylinder the rod goes in? )
