First check the adjustment of the cable. You need to reach inside the LF 
wheel, grab the cable, and slide it in and out to find the limits of its travel. 
Then put it in the middle of that travel so the center wire is putting any stress 
on the speedo head.

Lubing it may help, it may only need some light oil around the shaft, which 
you can do without opening it up. I lube the gears, etc when I rebuild these to 
fix non-functional odometers. I charge $55 for this. 

Yes, careful of the tabs and the chrome ring. It's easy to really mess them 
up as they are very soft.
