Speedometer rebuild

Post by Tagus »

I know this has probably been discussed here before. I'm trying to disassemble a Speedo from a '67 Moke and can't figure out how to remove the pin holding the odometer cluster in place. Any ideas, links?

Can you give a bit more detail? I have dismantled & re assembled many speedos, but can't visualise the pin you are referring to.

If it's the pin going right through the middle of the numbered tumblers, on some speedos it unclips at one end, then you can slide the whole lot out of the other end.

Brave move removing that. I've done a few, but I have to be in the right frame of mind!

The odometer cluster is made up of about 8 numbered wheels. They have a brass pin going through the centre. The brass pin is supported on either end by the speedo frame. It seems this brass pin should pull out but there has to be a special way of doing it.

I have never stripped on that far down, sorry.

I have been known to gently bend the tab of the frame back on one end, then put it back to normal after re-assembling. I don't know if that's the right way to do it, but it worked for me.

Seems there should be a solution such as aligning all the number to zero so that the pin can be pulled. Trouble is the wheels are locked in place so that's not going to happen. I'll think on it and probably end up bending the tabs.

Thanks for the help.

Oh, OK. You can move each tumbler to the left just enough to disengage it from it's brother and then spin them. It it's easiest to do if you work from the 1/10's end.

I have done this with some success in the past.
