Lotus Elan

Speedometer Rebuild

PostPost by: William2 » Mon Oct 14, 2013 4:16 pm

I am cannabilising 2 speedometers to make a good one for an S4 Elan. Can anyone advise on whether it is best to use a bit of grease or oil on the nylon worm gear drive? Also, is there a particular method in removing the speedo head assembly from the case? I have gently tapped out the pin holding the zero odometer extension adjuster and removed this but it still seems difficult to extract the head??

Do you have these documents / links? Pretty comprehensive stuff that may help. Sorry, I ended up sending both my tach and speedo off for repair, so not sure on your specific questions.

Thanks for the links (the first one no longer works though). After removing the innards of my Elan Speedo to refurb the case, several parts were loose :shock: :shock: The last of your links provided the answer to my thankfully short lived dilemma!

Does anyone have any original drawings of the gauges they could spare?

William
To extract the speedo innards, I had to remove the pointer and dial first.
Two levers removed the pointer easily, being careful to protect the dial surface. An extractor as in the photo would be good but I had no trouble.
The dial is held in place just with the two screws near the centre.
The works are held in the case by the two screws on the back.
I do not know about lubrication.
Best of luck

Thank you for your reply. Need to get stuck in now!

If anyone needs to replace the bezels/glass/seals on their gauges I have received good service from here - http://www.autoelectricalspares.co.uk/bezels-glass--seals-for-smiths--lucas--jaeger-gauges-68-c.asp.

William,

I never figured out how to get the mechanism out of the case. The odo zero pin wouldn't clear the bottom of the case before the top of the mechanism hit the top of case. In the end I decided I was likely to break it, so put it back together.

If you find the trick to it please describe it here!

"don't worry, feel happy"

Ha! An unlikely outcome, I fear. At least one of those tiny pieces would have leaped across the room and be hiding somewhere on the floor. ;-)
