Useful research.  After all these years I now know my engine was built in 1995 and is actually one of the youngest we have in the club, one of the last off the line before they took away the dizzy and went for wasted spark.  (Probably how Richard Stewart got them cheap, the ultimate 'bin-end' :))

 

And it was originally destined for a Rover 220, fitted with an air conditioner.  Which explains the Heath Robinson way the alternator is mounted, the original builder has put it on the mounting brackets for the aircon compressor unit.

 

Happy bunny.   Makes searching for spares SO much easier.

I think the 3-sizes is for a Type 9 gearbox (happy to be proved wrong).  Ours is just different teethed plastic inserts, easily accessible on the box.

Just seen this quote in an old post:

 

"...The MT75 was designed for many cars with different axle and wheel size.  So if you look at the mechanical design the speedo drive cog engages a helically cut gear in the box and can hence can have a variable number of teeth..."

 

Does that make sense ?

Nice idea, but the error is not as large as the Km/miles converter.

 

You will find that back in 2005 there were lots of people discussing this as all the Superspec kits came with the Yellow 22-tooth drive (Standard on the Granada).   What they should have come with is the grey 25-tooth drive from a Transit.   Quite a few seem to  have swapped the drives without any problem (that was when the 25-tooth one was available from Ford) to get it through the SVA.

 

See Post #5 at http://www.rhocar.or...=+speedo +driveas an example.
