OEM electronic speedo

[PorkChop]

Could you get a 90 degree speedo drive, like you can fit a Toyota one with the MX5 gearbox?

Finding out the Scorpio final drive ratio etc. shouldn't be an issue to figure out how different the Scorpio and Sierra specs are and whether you could swap from one to the other with no further work.

There are companies out there who can recalibrate speedos (the one I know of is Speedy Cables in Swansea). They charge £65 + VAT and up.

I think the cheapest and the easiest thing to do would be to get a 90 degree adapter. It could be pretty cheap if you can get it off a scrap car.

Thank you for the reply.
The 90° adapter is a great idea. But the only one I found for my gearbox is from Burton at £127
All the other ones I found are not for flanged cables...
Does anyone have another source for that?
Thanks.

Taxi company may be able to help as they calibrate for taxi meters,can you swap the electrical head from dash to dash ?

[voucht]

Thanks for the input Paul.
what do you mean by "the electrical head".
My current dash is mechanical, and the idea was to replace it by an electronic one, using the electric sensor of the MT75.
Thanks.

That was the thought Sylvain,remove the dial itself and replace, not sure if the MT drive would fit the type 9 and would also question the ratio of the drive.

Late model Granada had an electroic speedo IIRC. and should be easier to modify than a Scorpio one. The 2.9 Scorpio uses a 3.62 diff the same as the Sierra 2.9 although the speedo drive rate may be different on the Auto and Manual. ( if you can find a L8 Granada 4x4 with electronic speedo then your onto a faily good result I Guess.)

Would a new after market one not be an option. They're built to accept a wide range of inputs and should be programmable.

Thats if theirs a cheap enough one available.

If not, there's a million and one bike speedos that could be adapted. They look nice and are generally cheap and plentiful.

Thank you for the tip TT.
For now, I bought a new drive cable and it is working very well. I could reroute the cable a little to have a nicer bend, but still, it is pretty tight, and I think it won't last for ever. But I'm not driving a lot with the Roadster, so it will do for now. But next time I have a problem, I will check this Granada option for adapting an electronic speedo on my cluster, very good info. Thanks

Thanks for the input. Yes, it would be very nice indeed. But if I put an aftermarket electronic speedo, I will need to change my complete instrument panel, and add a tacho, fuel gauge, water temp, oil pressure, etc. of the same range as the speedo. And redo my dashboard. That is an improvement I'll do one day on the car, but I definitely don't have the funds for that at the moment, so I need to keep my Sierra's instrument cluster, and adapt an electronic speedo on it when times comes. Also, I'm not a big fan of the motorbike or motorbike like digital dash. But it is just a question of taste there ;-) Thanks!

You should be looking at a flange-thread adapter, like this:

It should not be able to get one made by someone with a lathe. I printed one on my 3d printer for the speedo hall sensor from a Mondeo (I made the plunge to VDO gauges with an electronic speedo. 5 gauges from ebay £50, the speedo £200). The standard thread for speedo drives is M18x1.5, just like oxygen sensors, etc. The disk might have a tab that would prevent it from spinning when you're trying to undo the thread.
