I just fitted a recently aquired really nice correct style speedo in to the oval. Thanks VW1960. This one is mint, the clear needle is really clear, red and green warning light bits are perfect. However in operation is a bit noisey. I think its cause the lube has dried out. What the best way to re-lube these things and were do you lube them???
:tree:beer:jesus

You would have to be pretty careful not to have oil inside the speedo glass..
You could try dropping one drop of oil down the cable entrance....
Are You sure its NOT the cable.... they can be noisy... especially when they are about to break.... I used to place a couple of drops of oil into the top of the speedo cable every now & then.... I have stopped doing that now as the oil is coming out of the little square hole in the dust cap!!!!

If a tiny drop of oil or 2 doesn't fix it....
You would probably have to pull the speedo apart.... I am about to do this... or I should say I am going to try to open one without stabbing Myself in the hand!!
I have an old speedo I am going to try with... I have opened speedos from japanese cars and I'm pretty sure there wasn't any lubricant inside the speedo... or though I like to lubricate everything.... with oil-grease-Vaseline or petroleum jelly. Most things I pull apart, I usually oil if its a moving part... One drop of oil works wonders....

Thanks sleepe , nice thought mate. Yeah the noise is pretty loud :thumb

Lee, dont think it is the cable because the noise wasnt there before I fitted this new speedo. And yeah I don't want to have oil ruin a prefect speedo needle and face and get all over the glass.
I have opened up a couple of bug speedos in the past, no real problem. Be careful you done slip with the screwdriver.
Or break the glass.
Cheers

use a blunt knife or flat blade n prise the front cover ring off. then theres 2 screws at the back which u undo and then the mechanism is right there.
no good trying to do it any other way. oil in the drive hole goes NOWHERE:beer

Thanks Dave you have saved me a bit of extra work. Was going to drop a little bit of oil down the drive hole and stick it back in. So I guess its the full works required.
Cheers

Up date, got the speedo out and apart and back together without stabbing my self thru the hand or wrecking it. And now its a quiet as a mouse. And needle dont twitch either. :thumb

If the needle is twitching its usuall the cable stuffed n needs replacing.
a few drops of oil down the cable wont hurt either

I've fixed a couple of squealing speedos.

The main shaft grease runs dry after 30+ years and it's this that starts to squeal.

You remove the speedo from the car, and gently pry off the chrome ring around the face - then the glass comes out.

Removing the screws in the back of the speedo releases the mechanism.

You'll see a 1/2 buried worm drive with some brownish lumps of grease (if it's original). Access to the main shaft is very poor, but after cleaning out the old grease (dig it out with match sticks or anything small, use Vaseline as new grease (it's light, but non-drying) and push it into the worm drive area. Spining the main shaft backwards will help drag grease down into the bearing area. The later speedos (with 10th mile odos) have better access to the shaft area than the earlier types. You may also be able to push some in from the cable end - you'll fill up the cable hole first but can dig that out later - just keep putting a dab of vasiline on the end of the shaft and press it in with your thumb.

Place a tiny dab of vasiline on the other gears (don't use oil - it might throw off on to the other workings), and remove any excess vaseline from the worm drive, put it all back together and it should be quiet for years.

Hi Rob, I put a drop of oil on the inside of shaft and regreased the worm gears. Have I done the right thing here?
Will even a small amount of oil cause a problem??
It seems to be OK so far!!!

Dean

yeah Vaseline would be better, as Rob says, the oil will probally soften the old grease and make it penetrate into the gears.

now you know how to lubricate the speedo, it will be easier net time it starts to squeal.

Well the run home from Apollo Bay along the Geelong Road has made me aware the "new speedo" is not reading correctly. Had a feeling that the car seem to get up to speed a lot quicker with new speedo.

The speed advice radar on the Geelong Road advised that I was travelling at 94kph and the speedo was telling me I was doing 65mph. Even rough conversion tells me that one is not right. And I think I know which one. Think a bit oil might have got into the works (magnetic spinning bit). So out she'll come again.
Will use Robs advice this time.

Happy New Year all

Dean

Dean I went under that radar on Geelong Road yesterday and the reading was spot on with Bel's which means it is wrong. From all other accounts Bel's speedo is roughly 10 klms p.h. over what she is actually doing:jesus

p.s. Happy New Year!!!!!!!!!!:party
