Re: Oscillating Speedometer
I remember those speedo reversing devices.
Every fly by night car lot had one.
Until the speedo law was passed.
Then they all mysteriously disappeared.

Re: Oscillating Speedometer
Using a powered tool on the speedo is never suggested unless you are faking the odometer reading on a working speedo.
If the needle bounces around SOMETHING ain't right... there are THREE basic component assemblies in work here, the speedo, the cable and the T/C drive.
A gummed-up speedo of unknown origin can be damaged no matter if a drill is forward or in reverse or at a slow speed. Something has to give here; the drill isn't going to bind and stop...the dried grease/crud MIGHT break loose....or you destroy your $500 to $1,500 speedo. That is why frozen speedos and drills are a crapsoot you may not want to lose, are ya feelin' lucky?
In this instance, a long time working speedo that just devoped a bounce is most likely to be due to the cable lacking lubrication and/or being routed the wrong way. Follow that with a speedo that hasn't been lubricated since WWII and finally, the T/C gear possibility.
Being that the fastest, easiest, cheapest, simplest thing to check is in fact the cable....remove, clean, lubricate, install correctly and go for a test drive and report back. Be sure that the little "keeper" on the inner is at the speedo head end when you put it back into the outer sleeve!

Re: Oscillating Speedometer
And where does one buy the special oil necessary to lubricate the internals of a speedometer?

Re: Oscillating Speedometer
I figured you had some on the shelf, Joel.
Only those of us that fit into the vintage category would have such a thing.
In this high tech, digital world things like "speedo lube" have become "obsolete" and "no longer available".
When is the last time you tried to buy a "points file" ??

Re: Oscillating Speedometer
The local shops the dealers sent speedometers to used it. There is one gentleman from the old days that is still working on starters and generators. The Ordnance Support Unit for the Guard had it on hand as they had an Instrument Technician. I have a couple NOS AC Speedometers on my spares shelf for my CCKW.
Go to your NAPA and Advance Auto Parts Store, they have Point Files by KD Tool.
I still have and occasionally use my point files, gotta be careful tho as the tungsten surface is skimpy compared to points of yesteryear.

Re: Oscillating Speedometer
I have checked with the local NAPA store. No point files. But may be a local problem. College boys have taken it over. They are good guys, but, me thinks they have figured out they make more money selling points than they do point files.
Ace ?? have one of those locally as well. A really great place. Never considered they would have point files.
Don't think I have seen a late model car or truck with a speedometer cable. Just computer sensors and wires.
Makes folks like ourselves a minority.

Re: Oscillating Speedometer
NAPA up here sells KD Tools. I bought a handful of Point Files to send as gifts to MV friends not too long ago.

Re: Oscillating Speedometer
The local NAPA guys might be able to get point files if I bought a case of them.
I can see it now. Everybody sitting around the Christmas tree, looking at each other asking, " what is this ??" Mumbling, " what did the old fart get us this year ??"
