other Odometer / trip odo vs cable ?

[deschodt]

I understand the odo and trip odo break easily from old age, and you need to fix it professionally...

But I'm wondering... if my trip odo reset button can still turn the main odometer one mile at a time whenever it's reset,

Could it be just the cable ? Or is that irrelevant ? 

 

Neither odo nor trip odo work, speedo works... Still same deal ? Take it out and farm out ?

If the speedo works, it's your gears.

 

You can fix it yourself- there are a couple of people who, on and off, make the gears.

 

They are relatively precise, but not hard to work on.

There is a how-to in the articles section of this site, which addresses the most common problem.

I found it helpful when fixing mine.  I did not need any new parts.  It was the typical gear slipping/moving on its shaft.

IIRC, the white 'gear' beside the numbers allowed the shaft to slip, which made it so the gears in the second photo no longer meshed.  I cleaned off the old dry grease and lubed it with Sil-glyde, (which will not harden like that).

I fixed it four years ago and it is still spinning fine.

It was a fun fix and you won't find much cleaner parts to work on.

Seems like you might as well have a go at fixing it, you can always send it off if you are not successful.

Jeff Caplan of odometergears.com spent most of The Vintage weekend working on gear replacement & trouble-shooting gauge problems.  After you get yours out & apart check out: http://www.odometergears.com/products/BMW/2002+Series+68-76/23

Hey Mintgrun,

Always enjoyed your "inventiveness" on solving other problems on these interesting cars and thank you for your contributions to the site.

Quick question, with what did you clean the old dry grease off?

 

"..you won't find much cleaner parts to work on..." -no truer words were spoken, ha, ha! It seems like anything I touch on the outside of my car leaves some sort of dirt or grease on my hands. I have this fantasy/dream of someday opening the hood and NOT getting thick, black greasy oily stuff on my hands when I touch the engine.

Thank you Philip for the kind words.  I was afraid someone might say "Really?  Those old photos AGAIN?" 

 

It has been a while, but I would guess I used a soft cotton rag to clean the grease off.

I heeded the advice in the article and did not touch the faces of the gauges with my fingers.

The glass lenses have stayed nice, since the back sides were cleaned.

The trimmed down toothbrush in the photo below makes a great cleaning tool.  I have some I trimmed even shorter.

The bamboo skewer wa used to spin/test the speedometer using a drill, (which, IIRC, spins 55 mph). 

I was lucky and my fix was an easy one.  I have no idea what all is inside the speedometer's 'transmission'.  I was glad I did not have to go any deeper into it.

I've done this fix before, when I bought my car the odometer wasn't working. Pretty strait- forward, push out the shaft without disturbing too much, hammer in a few knurlings for grip, and slide the white gear back on, good to go.

Thanks! The tutorial was a little vague on actual cluster removal. I'll start there...

Remove the black covers under the dash.  Reach up to the back of the cluster & remove the two knurled nuts.  Unplug the electrical connector and unscrew the speedo cable.
