1955 Chevy speedometer problem

[Guest F37Olds]

The speedometer on my 55 Bel Air has recently begun making a rather loud screeching noise and the needle is bouncing around wildly. I pulled the cable out, cleaned and greased it, but it didn't help. Is there any way to lube the speedo head or does it need replaced? It sounds like it needs greased if that's possible.

I use only graphite on speedo cables.

Yes, you can lube the head. I would use a light instrument oil. With the speedo assy removed, gain access to the speedo head. You will find a small 1/4 in. brass plug which will give you access to the shaft which can be lubed. I have done several with great success.

For lubrication of the head itself, I would use watchmakers oil. It is a fine grade of oil that won't just gum things up. I wouldn't use 3-in-one to oil the screech on my cat. <img src="http://forums.aaca.org/images/graemlins/smile.gif" alt="" /> There may be a cotton wick to apply the oil to - use a mirror to search for it if removing the head is too difficult.

Thanks all. Once the weather breaks around here, I'll give it a try.
