Wouldn't help me much. My 403 speedo needle waves around like an unlatched barn door in a storm !

Hi Dave,
My speedo does the same, its like a demented clapometer from the old game
show days or swingometer used on election nights. On a long trip I use my
sat nav at least I have some idea and the rev counter is at least accurate.
Has anybody a cheap dependable cure?
Has anybody any tips on removing a 406 onwards dashboard, to fit a new
clock, mine is only correct twice a day!

I did not open Greg's posting, but I believe it to be a spoof that I have
seen before.

Well, I never read your posts either Nic the .....

But this may solve your timing problems ! -- and of course the bezel could be changed / coloured black to match /fool the car wash judges !

And if you want perfection, this company will copy the original clock face for you.

dial restoration, uk

Or maybe you could have a face transplant and have one that is more pleasing on the eye !

Like mine :-)

Looking forward too not reading your reply !!

If you buy the clock gasket from Bristol and it is the wrong size - alter it until the hole suits your demanding needs.

Love and piece

wayward speedometer is often caused by a sticky or damaged / bent speedo cable.
The extra resistance in the flexible cable causes it to wind up like a spring and then unwind,
resulting in the speedo needle waving about all over the place.
First aproach is to take the cable inner out of its sleeve, clean and lubricate it.
If that doesn't fix it then it's usually a case for a new cable.
My speedo is dead steadybut 10% fast - and I've no idea why...

A spoof from Greg? His previous 247 posts must have been designed to lull us into a false sense of security!

Most of you will be running modern tyres which result in a lower tyre diameter than your car had originally, so your speedo will say you are going a bit faster than you actually are.

As Martin says, it's probably a case of poor lubrication or a worn cable. Premier Instruments in Canberra say that this is the most likely cause. Mine does it too and is due for attention. John Keighley

Yep - a new cable fixed my 408 speedo

Bought from Bristol Cars for about £20 and a piece of wee to fit - Just attach to the old one with gaffa tape a pull it through.

I think the old one would have been fine if I had made a plasticine funnel and let some light oil soak through overnight before reattaching to the speedo head.

I use the old cable with a cordless variable speed drill to test other speedo's. It's the only time I have had a Bristol speedo to 150 MPH !

Aha! I will try this on my old Land Rover when the weather improves -
hadn't thought of the cable being the culprit.
Mine waived around but then stopped close to it's top speed of about 40 mph.
Okay, 35 mph.
In this case the needle must have jammed as well. I recall all that's inside
those speedos is a magnet that rotates and a needle that tries to follow it,
attached to a weak coiled spring. Something to do on the kitchen table in
winter.... but too cold now to take it off!
Eric must be snowed in by now, up in them hills?

Difficult to judge this one — the wavering needle on two of my Bristols (one a 408) was caused through previous owners over-lubricating the cable and the oil (probably 20/50!) getting into the speedometer head.
