Odometer Stopped

I took out the dash console to see why the odometer stopped turning on my 88' Silverado. There are two plastic gears visible a small black gear that rides on a larger white gear. The black gear was cracked and rode itself off the white gear, might have binded and ruined motor. I took off superglued the black gear back together and slipped it all back together. Buttoned everything up and took it for a test ride. Still not working. :banghead:

I can only think it's the motor that drives the white gear has died. While it was apart a added a few miles on by turning the white gear and it has a serious wobble to it and the motor made a weird whining sound as I turned. I just thought it wasn't made to turn so fast.

Anyways can I get a odometer motor only from a dealer or do I have to buy a whole new odometer? Any suggestions?

Get one from a wrecking yard

Did you superglue the black gear to the shaft or did you just glue it and then put it back on the shaft--If you did not glue it to the shaft it will still slip.

I only glued the black gear back together. I was concerned if I got sloppy with the glue I might glue the two gears together. However, I was able to turn the white wheel and the black wheel did not slip. Maybe I should strip it down bare and give it a test on the way to the salvage yard, that way i can see whats going on.

I have fixed these on several trucks and if you don't glue it to the shaft it will still slip. JB weld will also work to secure it to the shaft and should be easier to keep from accidentally getting it where you don't want it. I also take the shaft with the odometer numbers on it out to prevent glueing anything else together.

Here is the pertinent part of the above thread:

"There is no speedo cable on 88 and up C-K series trucks. They are all electronic. These odometers are not hermetically sealed. In Texas and other dusty locations fine dust gets into the odometer and gums up the works so to speak. The black (on some is white)gear referenced as broken is the gear on the odometer shaft--it cannot take the torque caused by this and breaks or spins on the shaft. If you don't want to buy any new parts or can't find them you can fix the gear with a drop or two of super glue. After this dries, soak the odometer down good with a silicone spray lubricant to wash out the dust and lubricate it. Pat it down with a soft cloth to remove excess silicone spray and it should now work. All of the above assumes that you have removed the odometer from the instrument panel and are working on it at your workbench."

Yep, thats the thread where I got the idea to glue it back together. So I take it you haven't came across any bad odometer drive motors as of yet. BTW, the odometer was very clean, probably the only clean thing in this old truck. I didn't bother to lube cause it turns easily by hand.
