[Vwdiesel] 85 Quantum Speedometer

[Erik Lane]

The mechanic is right, there is one plastic gear that tends to crack
when it gets old, and then it no longer turns very well. If you're
comfortable taking the instrument cluster out then you can take care
of the gear yourself. I don't know if a gas speedo would have the same
gear, from my understanding they were available with different numbers
of teeth. Not sure of that, though. But it's not buried - once you get
the speedo out of the instrument cluster it's right there in front of
you. I've had excellent results on different cars by taking the gear
out, drilling the hole slightly bigger, and supergluing it back
together and onto the shaft. It seems that from the factory it was a
press fit onto the metal shaft, and once it gets brittle the stress is
too much, but when glued on the stress is gone and I've gotten
>100,000 miles on my current driver with a superglued gear. The other
cars that I fixed that way are still good, as far as I know, but a few
were cars that I no longer own, and one is on the car that sits around
for parts/back up car.

On all the A1 cars that I've done it's a small red gear on the side.
I'm not 100% sure that yours would be quite the same, but the design
will be similar, at least.

He referred me to a particular repair shop and a particular mechanic within that shop.  Guess what?  Retirement removed the mechanic and the computer age has removed the mechanical speedometer overhaul department.
