Starting to lose the will to live....well not quite but having taken an assortment of instrument clusters in and out of my car as well as disassembling my original one about 4 times now. I have reached a conclusion which tractor Dave pointed out a while back.
My car has the 7A 5 cylinder engine ( 20V ) , it seems that this speedo unit is different to all other 5 cylinder Coupes and saloons . Speedo parts are not interchangeable and it seems the speedo part of the motor also drives the odometer.
I took the little motor out as described in MikeS2 article which Slacky posted up, and guess thats all I need plus of course a needle that will fit back into it but finding parts like that are not going to be easy.
I started with an odometer problem caused by the disintegrating miniature plastic cog , but created another problem when I removed the speedo needle and damaged the pin that the needle is attached to.
I suppose another option is to ask tractor Dave to have a look at it/fix it but he sounds rather busy at the moment. Taking the dash in and out of the car every time to see if my "meddling" has fixed the problem becomes rather tedious in the end .....and that's putting it mildly. Still, I guess you'll all be telling me that's the fun of owning these old classics...... yeah right
