Never Been In Here Before, Inside My Speedometer/Odometer Options

[kconway]

I have an non-functioning odometer and figured one of the gears inside was broken. Following the Pelican DIY article I carefully opened it up expecting to find something broken. I don't see anything out of the ordinary but I've never been inside before.

With the trip reset cable inserted in the speedo port I spun it up with a drill. The speedo works just fine but the mile don't increment on the odometer. The trip reset works when turned except I can never get it to 0000. The "ones" column never turns to 0.

Anybody see anthing out of the ordinary or is this just a lost cause?

You can also use a pair of side cutters and put some diagonal dents or small cuts in the shaft where it fits in the gray wheel and it will hold. It's like knurling te shaft. The gray wheel probably starts slipping because the torque needed to turn it all is increased from lack of lubrication in the mechanism. Lack of lubrication in old stuff causes most of the problems from door hinges to latches to wheel bearings to steering boxes or whatever. If it moves it needs lube.

This works best along with distorting the ID of the grey gear. To distort the gear ID I use a small center punch and place a punch on opposite sides of the ID then turn the gear over rotate it 90 deg. from the first two punch marks and make two more punch marks. You should now have four punch marks ( two on one side and two on the opposite side ) at 45 deg. from each other around the ID. Note that the gear ID is now distorted. With the material on the shaft distorted and the grey gear ID distorted you will find it to be a very tight reassembly. I use a very small finishing hammer to gently tap the shaft through the final grey gear. You should now have a long lasting odometer/trip odometer. Just remember to NOT reset the trip odometer while the car is in motion.
