MGF Speedometer drive failure

[bigbadbikercats]

What it says in the title really. happily driving up the A14 this morning (top down, woolly hat and gloves on, radio up loud - it's the only way to survive a 5:45 AM start on a Monday morning...) and the speedometer needle just dropped to nothing without any warning wobbles at all, this was shortly followed by the power steering going AWOL (presumably because it relies on pulses from somewhere in the speedo drive chain to decide how much assistance to allow).

Any know "Gotchas" (bits which come unscrewed, particularly easy/cheap bits to try replacing) before I resign myself to paying someone to crawl underneath?

Come to think of it, does anyone know how it works? Is it a mechanical system or a pulse generator feeding an electronic instrument??

What year is the MG? Earlier ones are cable driven and later ones are electronic
Have a look here scroll down the LHS and find the section for the speedo cable....
