From the Speedometers suck department:

I replaced my speedometer driven gear last night. My speedometer is still wrong. Damnit.

First off, I jacked the car up, and I got the cable undone. Getting the housing that holds the gear out was a bitch. I finally had to just grab it with some channel locks and twist the bastard out.

Once I had it out, I peered in the hold. CRAP! Orange drive gear. Orange is 11 tooth. I had done all my math hoping it was a 10 tooth gear. My 29 tooth driven gear wasn't going to be right. It'll be closer than the 24 tooth gear that was in there, but it won't be right. I had it apart, and I decided to put it in anyway.

Except I have messed up the threads on the housing with the pliers. Off to H&S hardware to get a thread file. While I was there, I also grabbed some new bolts for the exhaust.

At home, I cleaned up the threads on the housing, and put it all back together. I also replaced three of the four exhaust bolts, and tightened them down. Less leaking now. If I keep this up, I might have a bug-free car in two years or so.

Off to order another speedometer gear...
