MG Midget and Sprite Technical - Speedometer dismantling

I am dismantling s speedometer for cleaning and general refurbishment.

Is there a smart way of removing the odometer setting spur that sticks out through a hole in the side of the casing. Although I have removed the bezel and glass and the two fastening screws on the back of the case, the innards don't want to come out whilst that adjusting shaft is still fitted. What's the trick?

Do you mean the metal shaft, or the knob?

If you look closely at the top of the plastic tube you will see a small pin securing it to the metal shaft - that needs to be pressed out to remove the innards.

No plastic tube Chris. It's all metal.
I have removed the knurled knob from the end of the brass shaft, but the shaft itself is still attached and prevents the main cluster from pulling forwards out of the can. Unless it's like a Chinese puzzle ?

In the past, I'm sure that I have been able to remove the innards having only removed the knob.

However, I also recall not being able to remove the innards of at least one speedometer without removing the screws for the face, allowing a bit more wiggle room. It is a bit of a delicate operation, though.

Dave, its a Frog one. It doesnt want to come apart with the brass shaft in situ, but I don't want to damage it by pulling to hard if its not supposed to come off.

I will try the 2 face screws - it is very nearly free so releasing those screws may be just enough.

That did it Dave. Thanks!
