1959 Edsel Speedometer problem

This is my first post on H.A.M.B, though I have found useful information on this website for years now!

Here is my problem: My speedometer doesn’t work. I was driving this week and the instrument cluster started making a loud grinding/screeching sound while the needle jumped all over the place. After about a mile or two the sound stopped and the needle rested at 0, no matter my speed. The odometer continued to work as normal.

I disassembled the instrument cluster today. It appears that the shaft on the end of the needle is no longer connected to the shaft connected to the “spinning magnetic wheel” (sometimes called the speed cup). I’ve attached a few photos to illustrate the point.

Here is my question: How can I re-attach these two shafts so that the speedometer needle will function? Do I need to just “cut bait” and buy a cluster out of a parts car? The end of the needle shaft has a flush edge to it. It does not appear to be “snapped off” with no visible signs of shearing. The spring doesn’t appear broken and has tension. The face plate on the speedometer is secured with small rivets, so I don't think I can remove it to get a better look at the problem. I was hoping I could simply press the two shafts back together and that they would click in place, but no such luck.

References: Part number is K-S 56594C N, made by King Seeley. Based on several videos and forums this same design was used in many speedometers in the 50s & 60s.

Thanks!

 

The speed cup can not be repaired it has to be replaced. The jewel in the magnet is also bad which caused the cup to break. This is not a repair you can do your self as the magnet jewel needs to be replaced and re-magnetized to calibrate the speedometer on the test bench.
You did not get any replies to your post because you need to do an introduction on the New To The HAMB page telling a little about yourself.

 

Thanks! I have posted in the "new members" section.

What service, otherwise I'd suggest finding an old instrument cluster on eBay, beat up ones are cheap, but a crap shoot if it is any good. One from a '59 Ford would likely fit. Overall one of the best looking dash clusters of the era.
