My Speedometer started making a "whirling" noise. I replaced the speedo Cable, and it continues. I assume it is the gears or the magnet. I have taken it apart as far as I can. Has anybody experienced this, if yes. Could you let me know what you did to correct? Does anybody know a good Speedo "fixer" that specializes in Antiques or better yet Packards?

Thoughts appreciated!

A whirring noise sounds like dry bushings in the mechanism. It is not hard to open up and get some light oil into it. I sprayed mine down first with brake cleaner, used compressed air to blow it dry and blast away decades of dirt, and then using toothpicks carefully dripped oil into all moving shafts/gears. Be sure not to knock the centre plate askew and incur the needle shaft to rub on the central hole. You can also drill out the brass cap as Big Kev did to oil the felt inside that bore too. His image describing that location is below.
With the speedometer head off you can also pull the shaft/cable and give it a good cleaning and spread some lithium grease on it before sliding it back in.

Thanks Bob! I will give that a go!

Follow on question. So drilling out that brass cap will not damage the speedo? that is the area the sound is coming from so it makes sense.

You might be able to get the brass plug out with a sharp ice pick. Be very careful working with the speedometer. Too much lubricant can do a lot of harm.
Any loose rust particles will get stuck on the magnets and cause trouble. I would not use compressed air on a speedometer. A light, non-gumming oil is best.

I did not remove the plug on mine. Kev found there was a felt wick behind the plug in the bore to hold the oil, so I just did as TxGoat indicated, used a toothpick dipped in light oil and let capillary action soak the area of the wick from the shaft end. You do not need much lubricant to get a good result. Overdoing it will only result in dust build up and gumming of the mechanism again in short order.

Hi all,
I just want to loop back on results. A tad bit of oil in shaft (with toothpick) and Lithium grease on the Speedo Cable did the trick. She is back to normal, no noise! Thanks too all for the input and guidance!
