950

[srivett]

You guessed it, I'm referring to the number at the bottom of the speedo. :lol:  It's just below the trip meter.  Anybody know what it means?  Could it be trying to tell me that I should get 950 km from a full tank?  What does it say on an American car?  I've also noticed that the redline marks are wrong since swapping transmission.  Could that 950 be the speedo part number for an AWY in km/hr?

Thanks, Steve

It's probably a VDO number or something. The speedos aren't specific to the trans. If you switch to a different final drive you just need to get the correct gear to go on the end of the cable.

Here's another one though, what's that line at 67mph in my truck?

I believe that at least for US market cars, that number is the RPM that the speedo drive gear needs to be spun at to achieve a benchmark speed, such as 60mph (although I can't remember the particular speed off the top of my head.)

So, if you replace another cluster and make sure this number matches your old one, you will have an accurate speedometer reading.

FWIW, '84 Rabbit Diesel L sold in the US market with the 100mph speedo and 3+E transmission has this number being "1575".

It is strange that they would have speedos that were calibrated differently.  I'm pretty sure Japanese motorcycle speedos all give the same reading for any specific cable RPM.  

Even stranger, my car now reads the correct speed with the AGS gearbox and speedo drive running the origional speedo.  I took the AWY speedo drive off of the cable when I pulled that gearbox.  It was off atleast 10%...I would be doing way over the indicated speed limit and still have people catching up to me.  Now I do 15 over (that's what you get away with around here) and I'm moving along with traffic.

I just did a search of an older vw diesel forum to verify the meaning of this number.  At least for US-market cars, it is indeed the number of turns the odometer should take for it to advance exactly 1 mile.

For an odometer that is in kilometers... maybe it is the number of turns to get the odometer to advance 1 kilometer?
