Odometer no turnee

conkeytonk · 10-21-2008, 12:55 PM

After 147,860 the odometer stopped working. The trip meeter reset but does not turn either, just hangs at zero. Is there a common fix for this issue?

The easy answer and often supplied is that you have a bad stripped gear or the gear is slipping on the shaft or the gear has moved on the shaft and needs to be pushed back. Many times the repair does not last. A search will find many solutions.

You can check parts houses for some gears.

Pelican has a tech section site based on the 914 guages and gives some insight.

I opened up my case by carefully using a flat tip screw driver along the crimp. I moved my gear in position and put a drop of glue on the shaft. Has worked for a few years now.

Thanks folks (Dirty little kitty?), I suppose there is a little troubleshooting to be done. Gosh I love this forum!

did you press the trip reset while rolling? if so this usually causes the brittle odometer gear (for which replacements are sold just about everywhere, i use rennbay) to shatter/crumble and make the odometer stop working. just count yourself lucky you don't have to mess with the airbag to take the wheel and gauges out so you can fix it. i've done a couple of the gears, they're not too bad, but it takes some patience.

oh yes, if you need a hand with it, i'm near stuart, FL... i'd be happy to help

Hey thanks Mike, I might as well replace the gear while that far into the guts of the dash pod. I have been meaning to replace the illumination in the pod and install a new dash cap that I bought almost two years ago so all this combined is a good excuse for me to suffer through the muscle cramps that will result from strange body positions required to accomplish these tasks. And yea, I’m glad there is no air bag on my model…as old as these ‘beauts are I would not trust any of them. I easily replaced the rather ugly OE wheel with a MOMO.

And just in from Paragon: a KONI kit with lowered springs to occupy my time off around Thanksgiving.

BTW, I’m a haul from you …up Gainesville way but thanks for the offer. I own a little piece of heaven near Indiantown however.

You could just wimp out like I did and mail it off to a friendly speedometer repair shop. I think the one I used was overseas speedometer repair located in Texas. Fast, friendly service.

Note that this was before I became aware that I could take it apart myself. If it quits again I'm planning to take it apart and have a look inside.

It is a very easy repair, but before you go out and order the gear, you will have to take out the speedo and look to see what the problem is. People were telling me that my gear was stripped, and was about to order the gear, but took it apart and found that the gear slipped and moved down the shaft just a tiny biT. Some super glue and 630 miles later, odo and trip are still truckin'. If you do have a broken gear, you will have to count the teeth on the old gear to order the new one, they sell 3? gears, 22,24,26 toothed gears.

in this case you were probably better off. as someone who's had some early speedometers apart, i don't recommend it. the early gears generally slip, and the later ones crumble. you MUST have a LOT of patience if you plan on doing the early model odometer fix.

steve - you were probably told by someone who had a late car that the gear was stripped... i assumed that a non-working speedo i was taking apart would have a broken gear as well, but just about every early odo proplem i've heard of has been a slipped gear.

I'm going to give it a shot this weekend. I'v replaced the sunroof gears, disassembled and realigned the cruise controld module and on a related task have built computers from the motherboard up so I should be able to tackle it. Worst case a refurbished VDO gauage.

i did this a couple of times on my '83. after looking at clark's garage, i must say that i am almost looking forward to doing this repair on my current vehicle (the odometer stopped working at 124771 and 777.1, if you can believe that). it was a major PITA to do this on my '83, mainly due to the odometer cable.

Being a divorced man I was going to leave that one alone. You’re a brave man Nynor! Anyways the new Hall sender for the Scirocco took my weekend motorhead time and the kids took the rest so I’ll try to squeeze her in again next week. BTW the Hall sender made the ‘Rocco purrrrrrrr.

nynor · 10-28-2008, 08:16 AM

brave? probably stupid!

i just noticed that she has 3 blog entries.... does this forum have a blog?!

from your sig, it seems you really like scirocco's. i know nothing about them. what is the draw?

conkeytonk · 10-28-2008, 09:23 AM

Mostly because I grew up with them Nynor. The Scirocco introduced me to the superior craftsmanship of German automobiles that saved me from being a muscle-car mantic. They handle nicely, are easy and cheap to work on, make a great daily and have a huge following. Actually any MK1 VW for that matter.

But I have since found Porsche, just another leap in my gear-head evolution. I’ll probably leave behind a few 944’ish masterpieces and a cherry 911 when departing this world as my two boys want nothing to do with Dodge or Chevy.

Thanks for asking.
