richard26 Posted May 29, 2012 Report Share Posted May 29, 2012 Coming back from a great weekend away the odometer stopped working, the speedo still indicates the speed and in a lot less 'shaky' than before. The trip meter also does not turn when driving but resets when turning the twister on the little cable. Any ideas, advice appreciated. Quote Link to post Share on other sites
Barry Posted May 29, 2012 Report Share Posted May 29, 2012 Mine did that so I took it out and discovered that it had jammed up so a little nudge was all that was needed.I think the plastic gear wheels get gummed up. Barry Quote Link to post Share on other sites
OldBob Posted May 29, 2012 Report Share Posted May 29, 2012 (edited) Richard, I had identical symtoms that you describe very recently myself. One moment everything was working - albeit with some speedo needle shake, then the odo & trip stopped working and the speedo needle became the steadiest I had ever seen. The odo did cut in again a couple of times before I investigated and when it did the speedo needle began to shake again - clearly a tight mechanism somewhere. I had to disconnect the drive in the end as the odo caused far too much speedo needle shake and it got very noisy. There is a blue drive wheel on the end of the stack of odo number wheels - I cleaned everything in this area and used a minute amount of light PTFE lube on the moving parts. Then I ran it up on a drill out of the car for a while and watched the odo - its made a huge difference to the noise it was making and the wheels are no longer slipping - if you do this try to run it on a drill so that the odo clocks-up some big numbers where at least 2 wheels at a time click over - this seems to be when they can get stuck. cheers, bob Edited May 29, 2012 by OldBob Quote Link to post Share on other sites
Jonny1970 Posted May 29, 2012 Report Share Posted May 29, 2012 I had the same problem a couple of years ago. After hours of fiddling and head scratching I decided to remove the unit and sent it off to be serviced/recalibrated and fitted a new cable when i put it back. No problems since (....touch wood!)

richard26 Posted May 30, 2012 Author Report Share Posted May 30, 2012 Jonny, who did you send it to for the service? Quote Link to post Share on other sites
Grabea Posted May 31, 2012 Report Share Posted May 31, 2012 Don't know who Jonny used but try Speedy Cables, they have many years of experience and lots of parts for older instruments. Hope this helps Graham Quote Link to post Share on other sites

stuart Posted June 3, 2012 Report Share Posted June 3, 2012 Didn't know they had Oddometers in LeMans Jags! They do measure distance covered for the 24 hrs.That determines the winner. Stuart. Quote Link to post Share on other sites
