Speedo cable servicing
Has anyone devised a means of lubricating or otherwise servicing the speedo cable(s) with a view to lengthening their life before having to replace them - and endure the wind-screen-wiper-like speedo needle behaviour so BX typical?

I have tried lubricating them with aerosol lube from the top when I was changing dash bulbs, but have been warned that oily stuff could creep up the cable and get into the speedometer workings, mine is currently wavering lots, a passenger remarked "Vegila speedo, vaguely around thirty MPH" and to cap it all the thing has started ticking too! especially when its cold, I suppose something very thin and liquid might help a bit.

I've yet to own a french car that doesn't have a wobbly speedo!
You have to be careful though, as if oil gets into the speedo head, it will read massively over the correct speed.
All I've ever done is taken the inner out, cleaned it with wd40 or similar, and then dried it before putting back together. Aparently they're designed to run dry.

this might be a signature

Hello mine is the same, did toy with the idea of using a couple of right angle gear boxes ( because 2 sharp bends because ot the change from LHD to our RHD is the problem.) but thought the cost would be prohibative, when the dash bulbs go then am going to try dry lube ie graphite to see if that will do the job.
Cheers

I have just had a flash of inspiration, when I used to play with tuning air rifles we used to use a molybdenum powder in a solvent suspension, it went in as a liquid then the solvent evaporated leaving slippery moly powder, that would do the job, all my dash bulbs are working at the moment so I will put off the moment.

Bob Smith told me when he visited me a yaer or two back that he had sprayed silicone spray at the back of his right on where the cable fits into the back. Thn he worked the fitting round and back and forth until it felt smooth as he claims (and rightly so) that any tightness at the point where it actually spins must have a big effect on the smooth running of the speedo. He tells me his speedo was as steady as could be long after he did this and no nasty side effects. Silicone spray doesn't attract dust and I'm pretty sure it also doesn't "creep" so is a safe conveyance around that fitting.
Also read this write up I did a while back which I found quite successful also.

By the time you're old enough to know it all, you can't remember why you were learning.

Have tried fitting new cables? and if so are they run in the correct routing, it's much easier to run them in an incorrect route but you will get tight bends and thus problems.Gareth Wales wrote:So, Ken, any hints or tips. In the past I've tried for months to get rid of the quivering needle.
the correct route can be difficult but worth the effort. I put one in MNDEs BX16 in about 10mins went in with no poblem, but when I did Tims TZD it took much longer.
