Recurring Speedo woes

[JimmyRocks]

I`m suffering a recurrent problem with the speedo. ☹️

Seems to be the familiar one of the short length of cable coming out of the gearbox breaking.

Have replaced it several times in the last couple of years, but it rarely lasts more than a few hundred miles.

 

Would it be an answer to convert to an electric rather than cable Speedo 🤔

Has anyone done this 🤔 and what parts would I need. I have tried asking CC who were unable to answer and haven`t got back to me. Have trawled through quite a few old speedo threads also.

or am I missing something simple in replacing the cable 🤔

Could it be that the angle drive is tight/seizing therefore putting an undue strain on the quill as it trys to turn it? Have you tried dropping the angle drive down and seeing how difficult it is to rotate the quill?

 

Could just be something simple like the bevel gears requiring lubrication, or even the main cable itself sticking in the outer cable.

Thanks Brent

 

Any thoughts on the ease of changing to an electronic speedo 🤔

It's usualy a kink in the speedo cable and it's usualy near the head. This is a genereal comment not 7 specific.

 

You will almost certainly find a kink in the speedo cable somewhere. Also a few drops (not too much) of 3 in 1 oil down the speedo cable is all that needed for lubrication. If you put too much oil down the cable it gets "wound" up and soaks the speedo innards. It also runs out all over your trousers.

Out of interest, where is the moving pickup on a Caterham for the electric speedo? Wheel or propshaft?

Neither, they use the same drive from the side of the gearbox tail housing as the mechanical.

Thanks guys

 

Not a kink in the cable, and bevel gears are well lubricated.

Seems to be the speedo itself. It sticks, but then gives with a click and turns freely for a while until it sticks again
