Hello All,

Hopefully, we're all out enjoying our little toys now - or at least we 
were enjoying them over the weekend... whatever.

My car has driven exactly 16.2 miles this year, according to the 
odometer. Now, while I did sleep rather a lot during college physics 
classes, I do know that there is this time/space compression thing 
defined by Einstien (and others, probably most of them women, I might 
add), but I also know that from my house near Boston, MA to Nashua, NH is 
something more like 45 miles, and so forth.

Having driven the car on about 6 or 7 similar jaunts in the last three 
weeks, it is safe to say that the odometer is not working. Well, neither 
is the speedometer, but seriously - who looks at that! ;-)

In other words, I've already chalked up something like 600 real miles to 
the 16.2 indicated. The car is running quite nicely thankyou.

At any rate, when the speedo first acted up, I was sure the the cable had 
broken, so I pulled out a space speedo cable from one of the parts carZ, 
and low and behold - still no speedo. Well, undaunted, I proceded to 
place the car safely on jack stands and then run a test to see if I could 
determine the point of failure. There's no doubt in my mind - the speedo 
driven gear seems to "skip" a bit if you hold the end of the cable at the 
end where it goes into the speedometer drive, you know - that little 
squared off end thingie, while the car is running and in gear.

Now I know this should not be, so I figured look at the Bentley manual 
for guidance. The reference indicates: "remove the bolt and then withdraw 
the assembly". Well, it does not appear that this operation is quite that 
simple... I've tried if on two different 'boxes, all with the same 
negative result.

So list - anyone know a trick to change the driven gear on a regular 1:1 
TR6 transmission??? I'm looking to see of maybe there's a tool or 
something that could be used to make the job easier.

And please reply off list - I'm about three or four weeks behind on the 
digest - spending _waaaay_ too much time on Khartu that last few weeks. 
But don't forget to cc the list for those others that might be interested 
in your wisdom...

regards, 
rml
