Tripometer Reset Disconnect?

[Threehz]

So my dash is out and since it's out I'm going to refinish it and fix all the cracks in it, I have all the gauges out except for the speedometer. The speedometer removal is as easy as the rest except there is the tripometer reset knob and cable, the knob seems to be attached to the cable (knob also cannot be pulled through dash) and the only place I can see to remove it from is right before the cable goes in the speedometer there is a TINY screw.

I can take pictures if necessary.

Anyone know how to go about this?

Also 77 280Z if it helps.

It's in the FSM, BE section.

Aha thank you very much!

Reviving this old thread, since it deals with an issue that I'm facing right now...

I'm in the process of removing the gauges from the dash of my '70 Z so that I can clean up the clear-plastic faces and get rid of some body shop dust that seems to have settled inside some the gauge cans. The dash is still in the car (I don't really want to pull it unless it's absolutely necessary), but the heater panel (and the heater assy) is out. I've been working from right to left as I remove the gauges, and all that's left now is the speedometer...

I'm pretty sure I can free up the two wing nuts (I've made a slotted socket to do this). Unthreading the speedo cable sleeve shouldn't be a problem either. However, I'm not sure how I’m going to get a screwdriver onto the little retaining screw that holds the trip odometer cable in place. The FSM (I have the 71 and 72 editions) says nothing about this. Someone posted part of the BE section for a later model year (not sure which one) and here the recommendation is to reach through the tach hole to undo the set screw. Problem is that, in my car, the set screw is facing towards the driver’s door, so I don’t see how I can get a screwdriver on it by reaching through the tach hole. At the same time, the space available to get at the screw from under the dash looks ‘challenging’.

Does anyone has any tips or tricks (e.g. some magic tool or combination of socket extension/U-joint/driver tip) for getting this done?

OK, after another search of the site (there seem to be a LOT of different ways to spell 'speedometer') it looks like I may have found the answer my question, c/o Captiain Obvious. In case anyone else is trying to deal with this issue for the first time, here's what he had to say:

"Yeah, that trip odometer cable... Barring complications due to a dash cap, pulling the speedo out would be half the job if it weren't for that trip odometer cable.

The speedo is pretty much designed to be able to be removed with the dash in the car. In typical Japanese fashion, they set everything up such that it's supposed to be relatively easy to remove the speedo. The electrical cables have significant extra length such that the speedo can be pulled generously far from the dash before you run out of length, and so does the trip odometer cable.

Yes, I said it, "and so does the trip odometer cable".

The PROBLEM is that they wrapped the trip-o cable around the HVAC ducting so that it didn't hang down on your knee or get tangled up with anything, and because of this, it's tethered too short to get to the screw to release it.

My solution was to reach up and unhook the fresh air duct hose above the drivers knees and untangle the trip-o cable from the duct. Once that is done, there is enough length to get the speedo far enough away from the dash to get to the release screw. I think I also pulled to steering wheel just to get more room in there to work.

I was pretty frustrated by the time I got the end of that job, so I may be missing some of the details, so YMMV."
