[Healeys] angle speedo drive BJ8

Hi Mike,
After about the same number of failures I found that the problem was actually in the speedometer itself.
In both cases where I have encountered the problem the odometer itself was actually seizing causing the cable to sort of corkscrew and then the angle drive failed.
If you hold the speedometer loosely in your hands and use a drill to run the drive, anticlockwise when looking at the back of the instrument, after a while you will probably detect resistance to turning.
I took mine apart and sparingly lubricated the odo and trip shafts and in both cases the problem was solved.

In the three years that I have owned my BJ8, I have gone through three right angle speedometer drives.  The failure is that the short coil spring drive from the transmission to the helical gear fails; it looks like a birds nest of broken wires.  I am aware of the critical spacer washer that must not be forgotten; in fact, this last time, I put in two spacer washers, trying to overcome any marginal tolerance issues.  I also lubricated the speedometer cable liberally with lithium grease.
I checked the autox archive and this question went around in 2009; at the time, the remedy was to use only graphite (no grease) to lubricate the speedometer cable.  Is this still the conventional wisdom?  Any advice on how to clean out the outer part of the speedometer cable?
Thanks, Mike
