Tachometer gear

[Fourthegoodtimes]

Hi, last year when I rebuilt the top end on my cb550, I discovered why my tacho reading was so erratic. I found that the end of the Tacho drive gear was bent. I couldn't get the part from anywhere and after talking with Nurse Julie I opted to have a local welder heat it up and carefully straighten it. It was partially successful, in that it certianly was less bent but he didn't want to risk fracturing it so left it at that. Now I am back on the road running the engine in it's really bugging me to have the errratic needle all the time. I don't suppose anyone on here has one - part number 12431323000 - that they would be willing to sell?

I will have a look tomorrow, does yours have the shim/washer on as, this can cause it to snag

I will check tomorrow. Thanks.

Hi Trigger, yes it does have a shim on it. It seems to be perfectly flat and doesn't have any obvious marks on it. However, if you suggest it will be ok to run without it I shall if and when I find a replacement.

No, if the shim is not fitted then they snag.

Found one for you. PM me your details and i will get the post woman on it
