Thanks Clive and Pete
I have the speedo off now and in bits on my work bench where i cleaned it and greased it up, i must admit i was a little scared thinking it would all just go BOING with springs and cogs everywhere haha but glad to say this didn't happen, i will test it tomorrow with an old speedo cable and a drill.
As for the right angle drive, the new one i bought recently seemed to work fine with my fingers, but it does not come apart, i did however keep the one i took off which does, i will take a look at it tomorrow and chop up the old cable and see if i can repair it, fingers crossed on that mission ( i actually love stuff like this)
any idea on how long it should be?
Best regards
Tim
