type 9 speedo options
whats involved to change a type 9 from mechanical cable speedo, to electrical output ??
also a standard cable driven speedo, is 1000 rev a mile
anyone know how many pulses per mile for a type 9
(guess the last bit depends on the diff)

speedo
Hi. have just purchased a revotec speedo direct - much cheaper than Demon Tweeks. Very easy to fit and callibrate - sensor uses back of wheel studs
on any wheel hub. Took half an hour to fit including making sensor bracket and putting hole in dash. No more cables!!!

Did that with my former seven. I bought a pulse-thingy that fitted directly onto the mechanical output of the gearbox.
I bought it at a company that installs the 'tacho'systems on trucks (the thing that logs the hours they have driven and rested). It cost
me a whole 2 euros and no brackets or anything were needed.

I Think you will find that some of the Granadas with Type 9s had an electronic speedo and IIRC there were two or three types of sender.

If anyone can post a link to an adapter that goes into the Type 9 mechanical hole then that would save a lot of issues with glueing magnets to props
etc....

i was wondering about something similar. already have the cable in the gearbox, so will maybe end up mounting the sensor somewhere near the dash
(at least until the cable breaks)

This is a picture of my sender when it was partially completed - it fits into the speedo cable hole, held in by the same circlip.
 
speedo sender
It's a steel toothed wheel that spins between a magnet and a hall effect sensor (which isn't in the picture - it's fitted to the lid
that covers the wheel). The wheel has a tapered square shaft that goes into the hole that used to drive the cable inner. As you can guess,
you'll need a lathe.
No dimensions, I'm afraid - I drew up some initial sketches, then modified details as I went along. It no longer bears any relationship to the
sketches!
However, it gave some problems a while ago, so I was planning to investigate the ideas shown on
this page. This looks like a fairly easy way of making a sender. In the end I fixed the
original one so didn't take it any further.
I have also seen a web page that described how to adapt a London black cab speedo sender to make it fit a Type 9... but I've lost the link.

I have a sender from a Granada in my garage somewhere if anyone wants to give it a try.
Note: sender now gone.
Also if you are using a Sierra dif then ETB does a speedo that works on a disk clamped between the prop and dif.
I understand that some people with live rear axles have used this setup but as the whole axle moves I don't know how they have fixed the
sensor.
