After last weeks posting about the Toyota Carina GT-R AA63 cluster I could not leave it on the shelve anymore…So I opened it up:

Carina GT-R AA63 cluster cleanup: opened up

First thing I spotted under the tachometer was this:

Carina GT-R AA63 cluster cleanup: check engine light
The check engine light! I already thought it was missing! ( ? ??)

And when continued to unbolt plate from the backside I saw this:

Carina GT-R AA63 cluster cleanup: identification
Some sort of identification for the cluster. The 4cyl must be useful information for the tacho (pulses devided by four) and the RH must mean it is a RHD cluster. The other two numbers don’t ring a bell. ?(‘?`?)?

So with everything unbolted I was able to access this:

Carina GT-R AA63 cluster cleanup: odometer internals
The odometer internals!
When pushing the black gears between the numbers to the left you can just change the odometer number on the left of it to its right position. Be careful and use something soft like a toothpick: I damaged one of the (not really important) numbers this way because I used a screwdriver! ?(???;)

I also saw this on the backside of the backplate:

Carina GT-R AA63 cluster cleanup: speedometer calibration
It is used for calibration of the speedo- and odometer! 637 revolutions of the speedocable is equal to 1km. If the cluster has the same number of revolutions as my current cluster it will be an easy swap! Otherwise I probably need to have the speedo recalibrated to the value on my current cluster…

On the other side you could see the fruits of my work:

Carina GT-R AA63 cluster cleanup: odometer adjusted
I adjusted the odometer from 171178 to 081178, which is quite near what the current cluster is at.

Carina GT-R AA63 cluster cleanup: closed up again
So, all that was left was a good cleanup of the backplate and perspex and put everything back together. ?(´??)?
