84 900T odometer

[eric43]

My odometer (total and trip) stopped working a week ago, so used john-w's description (06-12-01) of how to take the thing out and fix it. Got the speedo out, took it apart, put it back together, but couldn't find anything wrong. Spun it with a drill, and it seems to work fine. Sadly, I broke the needle off trying to pull it off, so will have to fashion a new attachment. I'm reluctant to reinstall it not knowing why it didn't work before. Any ideas on what happened?

Also, what's the purpose of the tiny drive cable in the upper right quadrant of the speedo?

I think it drives a counter for the oxygen sensor light (comes on at what, 80K intervals?).

As for the odo working - chances are that you "shook" the errant gear back into position while pulling the instrument cluster out - if you didn't re-fasten (glue) the gear into it's correct location I predict that your odo will stop working somewhere down the road -

'Course, I couldn't determine what gear was out of place. I don't look forward to taking the thing out again (just hope I can get it all back in right!), but I better make sure I make the needle removable. Thanks!

There's a gear attached to a shaft that drives the odometer - if it's sliding on the shaft (you can move it along the shaft) I'd suggest fixing it with a bit of epoxy (careful not to get it on the surfaces where the gears engage!) before you put the cluster back into the dash - I THINK there's a picture in one of the repair locked threads - in fact there is - on the second page of this discussion thread there are some really good pics and explanations -
