RE: [Chrysler300] Jumping Speedo Needle





I happen to have two ’63-’64 instrument panels out and disassembled.   Each speedometer assembly has a small hole on top of the threaded stub where the speedo cable attaches.  But the plug in the hole does not appear to be removable.  It is neither Phillips-head or slotted.   They have a small hole in the center of the plug that looks like a sharp punch had been used to set a plug in the hole, perhaps to locate and fix the position of the rotating shaft.  I don’t think these holes are very tiny Allen-head sockets bit I will pursue cleaning and experimenting.

 

Anyone know a little more about this assembly detail?

 

I can get each speedo up to 12 MPH with a little spin on the shaft and both seem smooth after 50+ years.

Josh, there is a product called Chain Life (also for cables), brand name, Champions Choice. It is a foaming lube (aerosol), that clings under sever pressures. Internet search brings up several brands. I suspect private label packaging by Champions Choice. Some are called chain/cable lube. Everyone should have a can on the shelf.

 

Another point about speedo lubing. On the back of speedo where cable attaches, there is a small lube cap that is knurled to grip and unscrew. You have to grip with pliers to get it unscrewed.  It is vertical and hard to get at (get a light and crawl in), with speedo in dash. inside that small cylindrical cap there is a felt wick that dried out years ago.  It is essential to remove the wick and soak in light oil (10 w, 3 in One, etc.), and a couple of drops in the opening where wick was removed. This lubes the shaft going into the mechanism. A must do.

Hello guys,

My 300D speedometer needle is starting to jerk around just a little.

I'm guessing something needs lube? Can you guys offer any suggestions?

THANK YOU!!!

Josh
