speedo cable
I had the speedo serviced by VDO so all is good there, installed a new speedo cable so all good there, 87 k down the track and the speedo stopped
working, removed it this morning and the cable has broken off at the point it goes into the speedo, anyone had this happen and can hazard a guess
why?
Thanks
Don

How does the cable run to the speedo, does it have a tight bend near the speedo, this is the only thing that i can think of that would fatiguge the
inner cable enough to break. th bigger the bend radius the longer the cable will last.

The cable runs almost directly into the speedo, virtualt no bend at all, the thing is that the previous cable lasted long enough to round off the end
down at at the wheel grease cap, so it had been in as long as I've had the car, this one broke right at the point where the cable ends and the solid
bit that goes into the speedo starts, very strange.

Might just be a poor quality cable.

It's getting twisted off because there is too much resistance somewhere. There are only two places the resistance can be: in the cable or in the
speedo. Get a new (good quality) cable, put it in the car, leave it disconnected at both ends and try turning it by hand at the wheel end - does it
turn freely or stiffly? Now connect it to the speedo and try turning it by hand at the wheel end again - does it turn freely or stiffly? Now you
should know where the problem is. (Don't assume that the speedo must be spinning freely because it's just been serviced, we're all human and
mistakes can happen)

Odd one..
I can't remember ever breaking one but have replaced them over the years [a long time ago]
but once the needle starts swinging I replace them as usually the strands break one by one
but I cannot ever remember one breaking off at an end..??
there shouldn't be any resistance at the wheel end of the cable..
cheers

thanks once again fellas, the speedo spins nicely by hand and the cable can only enter the speedo in a straight line as there is a hole in the body
where it comes into the "cabin" that keeps it lined up, if the cable wasn't turning freely in the outer then surely it would have broken off at the
stub axle end. I've replaced it with a longer second hand cable that I had but havn't tried it yet, the length of the cable shouldn't be a problem
as once it goes through the panel it can loop around till it enters the rear of the front stub axle, so no tight bends, really wierd situation but as
cam070 said I'm leaning towards a faulty cable, I'll take it back to the supplier to see what they reckon.
