Hi, The odometers in the speedometer of my 1973 E-Type don’t work, I took it apart and found a red plastic gear with a flat spot. It drives a shaft with an offset peg on it’s end that operates the little arm that indexes the gear on the odometer wheel to increment the miles. The red gear’s shaft was glued in it’s bore from dried lube. Anyone know where it’s possible to get the red gear and it’s attached shaft ?
This is my list of outfits that rebuild/restore gauges.
I used West Valley for tach, speedo and all four gauges.
Still in the middle of my restoration so I can’t talk to quality of the their efforts but others on JL have used them and may chime in
Don’t know that any of them will sell bits and pieces vs offer to rebuild the entire gauge

Hi, I’ve almost certainly have this gear along with most other parts for speedometers, tachometers (both magnetic and chronometric) and clocks If you can give me a tooth count on the red gear I will have a look.
West Valley did my speedo and Tach and they both work perfectly. He even changed the speedo gearing to account for my change to a 3.07 differential gear set.
That would be incredible if you had the part !
I would gladly pay whatever you want for it.
It has 32 teeth, measurements according to my eyes and micrometer are:
OD of the red gear is about 0.435 inches, OD of the shaft is 0.197, total length including the shaft and offset peg is 0.868, thickness of the red gear is about 0.171.
Not to be cheeky but I found there was no spring holding the white plastic arm against the odometer gear. The arm has a big hook on it’s bottom in the attached photo that I thought would attach a spring. Do you know if there is supposed to be a spring there ?
Thanks again for looking for me !!!
Craig thanks for that long list !
I’ll look them up.
Doug, thanks for that I will look them up.
Hi Steve, I tracked down the gear and shaft. As for the spring I think there should be some sort of mechanism (spring?) to hold the pawn against the gear. The speedo appears to be more modern than the ones I usually work on so I will need the p/n from the speedo face so that I can find one in my stash and look at its return mechanism. I do have a bunch of springs so I may be able to find a suitable one.
$30 USD for the gear including postage (Iwill need your address) and including the spring.
I used West Valley for my 69 S2 coupe’s speedo… it made a noticeable racket at any speed and the needle bounced around. Turnaround time about a year ago was less than 3 weeks. Works great and is quiet.
Second West Valley I’ve used them on several cars and tachs and speedos and everything is spot on.
That is awesome Hugh !
Here is the face of the speedo, I’ll send you my address via email, replying to your notification.
It’s a V12 speedo, 1973.
Just testing to see if this shows up on the forum before I send my address.
Otherwise do I need your email address ?
I suppose we should take this offline please contact me at my email address: firstname.lastname@example.org.

I had a similar, but not quite the same, issue with the gears in my speedo. There are two of them, one for each of the odometers, and both had cracked, causing an erratic needle. Morris Mintz at West Valley Instruments, who has done great work for me on a couple of gauges, has the gears but will not sell them - I asked, and quite understandably he declined - his bread and butter is rebuilding gauges and those gears are not exactly easy to come by. In my case I inquired about alternative sources in this forum and fellow llster @gbrinker generously sent me a couple of spares he had, gratis. That was 10 years ago (and still working great, Gary. Thanks again!)
You’d best be advised to figure out and address whatever it was that caused that gear to fail. In my case it was dirt in the gauge.
In conclusion to this topic I got the red gear from Hugh, who lived nearby and we met at a car show. I have installed it and it is wonderful to see those odometers tick over again !! Thanks again Hugh who has an excellent stock of gauges and spare parts.
