NP 205 Speedometer worm gear

[Elutheros]

My speedo quit and I'm trying to diagnose the problem. Replacing the speedometer cable had no effect, so I pulled the VSS out of the T/c and found that the worm gear will spin using my finger through the hole for the VSS. Seems like that should not happen. Anybody ever encounter this?

i have split them before....is it a white 7 or 8 blade?


usually the driven gear gets worn in the center.

I can't see which color or number of blades due to the position of the hole. I'll have to get a mirror and take a look. I'm using a white drive gear on the cable end and with my 3.73 gears and 33" tires it's more accurate than my vehicles with electronic speedos.
