Odometer works, Speedo dead.

[timgray]

Ok what would cause the Odometer to work perfect but the speedo stay at 0? Is there a fix or do I need to find a used speedo and try to get the odo set to the right numbers?

The odometer is gear driven.

 

The speedo moves by a magnet spinning inside an aluminum cup. The shaft hangs in tiny bearings, just like the moving parts in a watch. Doesn't take much to gum them up. A bit of cleaning and lubrication may solve your problem.

 

Insect nest or spider web will lock it down tight.

I have a couple of '83 instrument clusters if you can't get yours working. It's not too bad swapping out the speedometer.

How much do you need for a instrument cluster? always good to have parts on hand when I open things up for repair.

I have an 85 speedo I could send you next week for shipping costs, if you still need one. Came with a cluster I bought for a CMU, and I have never used the speedo. Probably works, though. Let me know if interested.

Pull out the Instrument cluster, open it, clean the Speedo parts, also be sure to pull out the drive cable, and clean and lubricate it.

Most likely a good cleaning, and lubrication job will fix it up OK.

 

Good time to also replace all of the Instrument cluster light bulbs !!

 

While your in the area, be sure clean all the connectors on the Plugs for all the relays located in that area.

I am interested, in fact I'm interested in the whole thing minus a CMU or even the other meters. I have an idea that I would like to work on that needs the dash cluster.

chk the cable too Had my speedo cable pop loose on the road once

[timgray]

First thing I checked when I noticed it, then I noticed the Odometer was still ticking away miles.... So that means the cable is good. I do need to give it a good cleaning though.
