Smiths jaeger chronometric speedometer pin drive replacement

Post by adz25 »

Good morning

Can anyone tell me if the pin drive shaft on a jaeger chronometric is removable please? They don't have a retaining clip/plate like the square drive ones do. I don't want to punch it out and break the casting unless it's meant to be driven out!?

Many thanks

If you stare at for something long enough you find the answer!

For future reference there is a very small mild steel rivet pin which joins the worm drive sleeve to the pin drive shaft. Carefully drill it out and it separates into a number of pieces!

Best regards

Adam
