speedo fault

[jaycee72]

Hi Guys

I'm the proud owner of an orginal superlight ('98 no56) purchased through sound advice from folk on this forum. Shamefully its gets very little use, but following a stint off the road the speedo has packed up.

I've had it serviced locally, but speedo is still not working. Following advice the part needed was a 'speedo drive', I'm keen to have a crack myself rather than going back to the a garage. Part sourced from Caterham, is this a simple job or am I missing something. I hear story's of gearbox out?

Thanks in advance
Jon

Behind the carpet on my drivers side transmission tunnel is a removable grommet for access I believe.

Is it the angle drive? (or is that for the rev counter?)

It is indeed the angle drive on the gearbox which runs the speedo / odo.

However I'm sorry to say that the problem is often a bit more of a pain in the arse than the angle drive itself failing. What often happens is that the worm drive on the output shaft comes loose and moves away from the worm wheel, disengaging the drive. Once this happens your only real option is to get pretty seriously involved with gearbox internals.

My old car had been converted to electronic speedo for this reason.

Hi Jon

I've an early SL with the same problem - tried a new angle drive and quill but no good - as mentioned by BritishRacingGrin it's probably your gear box - when I've some spare time I'll be converting to an electronic speedo. I've a new angle drive you're welcome to try if you want...

Cheers
