Speed Odometer Gears
 

Tha odometer of my 911 is not working. The milage counter is working but it don't register how many miles I have travel from here to there .
Where can I get the famous gear that worn out?

Check the search feature, my friend.(Jeez, I sound like a true Pelican.)
Many, many thtreads and info on this. Hollywood Speedometer seems to be the preferred repair shop for this. IMO, I wouldn't even try to DIY. I did and what a PIA! Ended up sending it out anyway. DOH!!!

Not a bad job for a DIY, take your time and follow the directions in 101, also do the search as directed, there are many detailed instructions (including my own). I'll tell ya, you can spend $100+ for someone to do it for you, or $25 and a couple hours yourself...your choice.

Okay
 

Thank's all for the Information

Gues what..?

I just opened the Speedo as required and found that the gear is completely desintegrated.
The only info. that I have is that the speedo porsche part is a 911 641 545 01 and the speedo runs or is calibrated 85mph and 140km. This is a 1982 SC Targa
I just wonder If someone of knows how many gears.

Thanks for the help

Fixed and working perfectly

Good for you! That WD40 tube actually looks pretty good.

If you have access to either a GPS or radar, you should check the accuracy since the needle was removed.

I don't get what you mean about the wd40 tube? I did the same thing two weeks ago. Replacing the gear was easy, but I broke the needle shaft too. I ended up sending it to North Hollywood, so I didn't save any money, but I learned the proper way to remove the needle - twist counterclockwise while pulling - no sideload. I would do it again if I had to.

I think he's saying his needle (not the shaft, the orange indicator) broke off and he replaced it with a section of a wd-40 aerosol tube

No I meant The shaft...!
I drill the original shaft bearing to the size of the WD-40 size tubing and installed in place of the needle shaft

Sorry I don't have a photo since I was so in to it that I forgot.
Then I replaced the counter face

And then I instaled the counter needle. There is a mark for the counter nedle so that you can put it in the proper position.
I just try it today and it is working perfect
very sory you guys that I din't took pixes because is an alternative fix

oh, my bad. Now I see. I never got that far into the guts since my needle stayed on the whole time. Very clever - and pre-lubricated with WD-40!

The drilled hole is 1000th of inch biger than the tubing and it moves freely

Which Gear?
 

I have a 85mph/140kmh speedo. I need the gear but mine has broken into little bitty pieces. I was told I need the standard 30 tooth gear. Does anyone else have any knowledge on this?
