Latest challenge with my new 55...Speedo will not go over 30 mph! I lubricated the cable, so I presume the problem is in the head. Could it need lubrication? Is there a way to do that without removing Speedo?
Thanks.

To avoid any damage you might want to take your speedometer to a speedometer shop and have them check it out and repair/lubricate the speedometer if necessary.

I agree with the above.
The needle may be toching the face but I would remvoe the speedometer and have the head cleaned lubricated, and recalibrated

Apparently my biggest problem is my memory. I removed the gauge cluster and checked the cable...it was dry. I lubricated it with chassis grease and put it back. I removed the speedometer, found a short piece of cable in my attic and connected to my drill. It went way past 30. Since I had the Speedo out, I pulled the small plug but found no wick. Shouldn't there be a wick to hold a few drops of oil? I added a few drops of clock oil, and replaced the plug. To test it I attached the cable to the back of the Speedo (without the gauge cluster) and took off down the street. The speedometer again went past 30, but it wavered up and down by about 5 mph. I thought maybe the cable needs a little more grease?

The grease may not have gotten far enough down the cable, try a little oil.

You would have been better off using either regular speedometer grease or a white cup grease instead of the chassis grease.

What could I make a wick out of? Cotton twisted?

I made a wick from a small piece of cotton and lubed it with clock oil. When I reassembled the gauge cluster and installed it in the car the speedometer would not go past 30. I tried several things, but finally realized that the Speedo needle was being stopped by the "L" shaped needle of the reproduction temp gauge. To correct the problem I bent the needle of the temp gauge to straighten out the "L". It took me a long time to find this problem because I removed the temp gauge each time I removed the cluster from the dash. It was apparent only when I tested the Speedo with the cluster resting on top of the column with temp gauge still attached. I was turning the Speedo with a drill motor, and every time it hit 30 I could hear it hit the temp gauge. The cluster is now back together, installed and working smoothly.
