Odd issue with my repaired ODO

[Roverguy]

So, my OD on my 74 did not work from when I got it.

 

Finally got around to pulling it and doing the repair to the digit counter.

 

I pulled the shaft, made a ding in it and reinserted it so the gear had grip on the shaft.

 

Installed it and wala it works; but here is my question.  The trip works normally recording miles and tenth, but the last digit to the right which I would assume is the mile is changing on the tenth of a mile??

 

I have  5 digit odo as all do; that would make it a 1000 mile odo, 9999.

 

What's up with this..

 

Am I missing something?

 

[Conserv]

The trip odometer — four digits, the last one being tenths of a mile — reads from 000.0 miles to 999.9 miles, so, yes, it’s a 1,000-mile trip odometer.

 

The (cumulative) odometer — five digits, the last one being miles — reads from 00,000 miles to 99,999 miles, so, yes, it’s a 100,000-mile odometer.

 

Did I misunderstand the question? ?

 

Regards,

Well Steven...

 

That depends!

I guess I wasn't clear.

 

The main, cumulative odo is 5 digits as you say, but my fifth, last digit to the right is rotating on the tenth of a mile.

Mine did that when I dinged it badly. My fix was replacing it ;-)

 

You may be able to smooth out what you st dinged.

 

Good luck,

Sorry,

Lookey that!  Silver dollar speedometers (pre-Modell 71) only had three-digit trip odometers?

 

Best regards,

Most likely a 1600 speedo. Check the hash marks.

 

;-)

 

Thanks photobucket, for spamming my pics....

It’s got a tach, however: rare on 1600’s... ?

Negative orig to car, dated 3/74.

Maybe I marred the shaft under the digit wheel also?

I'll  check tomorrow.

The shaft should only be marred under the white gear, correct?

You know of course, Steven, that the pic is from my car, which is of course, all original.

Early 02s (1600 and 2002) with "silver dollar" instruments don't have a tenth's number drum on their trip odometers.  Neither the early or late cars have a tenths number drum on the main odometer.  The tenths drum wasn't added to the trip odometer until the modell 71 and subsequent cars (black face speedos).  So  a three digit trip odometer only rolls over once per mile.  

 

 

You can always order a set of replacement gears from www.odometergears.com.

Yes.  That was my guess too.

 

My first attempt at marring the shaft was temporary at best.  The second time I clamped it in a bench vise to put teeth into the shaft.  Aggressive, but it hasn't been a problem since.

Mine is doing the exact same thing. I have purchased both new gears, led lights and a new bezel .

I plan to clean and go through it pretty soon to see what I find.

Their is no info on anyone having this problem that I could find.

I cleaned up the shaft and reinserted.

 

Based on my bench test with my drill I think it is working.

 

Will install and go for a ride and report back.
