I have reassembled the unit without holder & glass, attached the drive cable and run it slowly with a battery drill.
The magnet rotates OK so the drive shaft is engaging OK, but there is a lot of vibration especially when you speed up the drive.
the needle does move but only by a few tho revs then starts bouncing wildly.
It seems like It needs a specialist to have a look, any ideas

I see, so it's possible that there is nothing wrong with the needle spindle.
If the drive cable is not engaging corectly then it may not be rotating the magnet to pull the needle spring around.
I will have another look later today and let you know how I get on.
Thanks

The cable drive spindle looks OK

It seems to be the actual spindle that the needle sits on that's loose.

It is a short spindle about 1/4" long with the spring attached .


I just can't see how it's supposed to locate with the cable drive spindle below.

Hi L.A.B.

Thanks for your reply

Yes it is the Magnetic type

I have taken off the needle and the clock face.

I am now left with the needle shaft which locates in a small hole in a flat plate but it only just locates in the hole.
under the plate is the rotating magnet.
The needle shaft has a clock type torsion spring that locates on the side of the base plate.

The problem is that it all seem very loose.

Maybe something went missing when it stopped working but without an idea of how it should look I'm a bit stuck.

Thanks
Ron

Hi Everyone,

I was just wondering if anyone has taken a Smiths Tacho apart, (it's the one with the grey face fitted to most 1969 Triumph / BSA models).
Mine stopped working and after checking the cable was still working I decided to have a look inside   ???.
Appreciate any advice from anyone who has managed to take one apart and get it working again.

Thanks
