I need a new Speedo cable for my 63, was looking at rock auto and was wondering if it was the right length and if anyone has experience with them? Also what lube do you all use? I pulled mine out and it was really dark, looked like grease but that seems a bit thick. Please be specific with the lube part, really want to get that part right.

Is the old one broken or just gummed up?  If it's just gummy, use some brake kleen to remove the old grease, then use powered graphite to lube it once everything is clean. Meazure your old one and call Rock Auto to find the length of tbe new one.  You can probably use one thats a little longer without a problem.

Old one is broken. And graphite, like for door locks? They have stuff like this at the ace hardware down the street from me. https://m.acehardware.com/product/index.jsp?productId=53384466

 

Comes in a tube, or spray can. 

Powered usually comes in a tube like antibiotic cream.  You squeeze it and it puffs out of the tube.  When you get the new one pull the cable from the sheath and see how or if it's lived.   If not, "puff" some powder into the sheath then reinsert the cable. You want to use a dry lubricant.  If you use a wet one, it will gather dust and dirt and eventually gum up again.

Do I only puff into the sheath, and not the cable itself before reinsertion? I would imagine I just use half the tube on one opening then the other half on the other opening, since it really isn't a big tube. Can it be overlubed?

If you try to coat the cable, you'll have almost all of the powder on the garage floor.  Squirt some in the sheath, and insert the cable. Pull the cable back out and see if there are any uncoated places. Repeat.  Slide the cable in and out until everything glides easily.  I would imagine that you can get too much in the sheath.

In my shop I've always used a tube of engine assembly grease to grease the cables after cleaning them thoroughly. Never had to go back in

and fix it again ever. My  GTO speedo cable was lubed this way 40 years ago....still works great with no noise. The original lube failed at 8 years

of age. Engine assembly lube is available at any auto parts store.....it has moly- graphite in it.

I have a large NOS tube of genuine AC Speedometer Cable Grease from the 1960's. It is a cream-colored grease product, not quite as thick as the engine assembly lube Seafoam65 has used successfully. John

Curious if the tube says what the lube is made of? Obviously that stuff works, or else our rivs wouldn't have working speedos from the get go. I will try the graphite first since i already have it and see how it works. Getting the cable in the mail today.

Well over the past 50+ years, we've learned that eventually the original lube will gum up.  The good thing about it is that we'll probably not be around when these cars are 100 years old so we'll never see it gum up again.

Interesting thread as my speedo dances around, especially when the car is first driven.

 

What/how is the best way to change out the cable?  I have a new cable, but not the casing.  Can/should I take it off the transmission, pull the cable out, lube the new one going back it?  Or, do I need to get behind the dash and take it off at the speedometer?

 

Advice is always welcome.  Sun is shining here, roads are dry, and I think all my lights are working.  Riv will get a run this morning.

What you're describing is at least worth a try.

There's no mention on the tube or the box, as to what kind of grease is inside this NOS tube of genuine AC Speedometer Lube. I don't know if it was some kind of proprietary AC formula or not. I recently removed the metal screw-on cap to see what the grease was like. It appears to be in good condition (no oil separation or hardening), even thought I'm pretty sure this is a 1960's-vintage product. John

Pull the cable, hold one end between your thumb and index finger, then roll it back and forth.  If it "flops", it's kinked -- and that kink will make the speedometer bounce.  Good cable or not, lube it up and reinstall.

 

A bouncing speedo is a minor annoyance by itself, but it's a real PITA if you're trying to use cruise control.
