Hey Mike:

You need to make your hand very very small, then reach up behind the dash and unscrew the wing nuts holding it in the opening. Then just remove the tach through the front.

Unless you have a dash cap, then it could get interesting.

Don't forget to disconnect the wiring. Luckily with a 280 you CAN remove the tach. A 240 requires at least the wiring to be left behind.

what you may want to remember is that the tacho in the 240z 71 model

will not start without it being connected

I posted a thread last week asking for advice on how to remove my Spedo/Tacho out of my 71' 240z.

Someone told me the cable to the tac will un-screw and you can pull it off the back.

That doesn't work.

How do I get the cable off the back of the tac.

The speedometer unscrewed but the tac does not.

Please help me.

So now you want the CORRECT answer?

Neither the Tach nor the Speedo go out the back on a 71. They both come out the front.

The reason I mention that a Dash Cap could make for some fun is that the "cone" of the instruments is pretty snug within the opening of the dash. If you do have a Dash Cap, the amount of material that the cap inserts into the instrument opening, depending on the thickness of the cap and the transition from original material to the cap, will / may cause the tach/speedo to hang up. At that point you literally have to work the gauge out and push it past that necked down opening.

Since I've already used more words than Auntie can handle, I'll explain the removal a bit better.

From the BACK of the dash: You'll need to remove the two wingnuts holding the tach and speedometer (each has 2 wing-nuts) as well as the strap that connects the two.

The speedometer is the only one with a cable attached to it, and that's screwed onto the back of the housing with a large diameter collar. There's also a smaller cable that's attached to the Trip Odometer Reset Knob on the Left side of the Steering Column. Simply pull down on the knob and the cable will slide up to the back of the dash area.

The tach should only have a 4 wire connector (2x2 thin spade) going to it. No Cables, and no other connections other than the instrument lamps.

The instrument lamps going to each should be easy to disconnect, just simply push on one side and they'll pop off.

Once you have the lamps and the cable for the speedometer off, as well as having removed the wing nuts that hold them to metal straps attached to the dash, they SHOULD slide out the FRONT of the dash. You may have to push from behind, but that's all it should take.

Hope that helps

I just realized the error of my explaination.

I am having problems with the cable that attaches to the Trip Odometer.

Everything else is un-done, un-screwed, gauges pulled out the front of the dash.

I am down to the Speedometer. Everything is loose and the gauge is almost out, BUT the cable to the tripodometer is still attached.

Please give me a little more detail on how to detach that cable please.

Thanks,

If my memory holds,

there is a tiny philips set screw that holds the collar from the cable on the shaft coming out of the speedometer, loosen the set screw, adn the parts should be seporable. Other wise take the cable loose at the knob end, and leave it attatched.

The Trip Odometer Knob turns the whole CABLE. There is no sheath on that cable. The knob is splined female and the cable inserts into it and is held by pressure from the knob.

Simply PULL DOWN on the knob, the cable collar should stop the cable from protruding through the dash padding and allow the knob to slip off the cable.

Once you've done that, push the cable back UP into the dash cavity. Then reach from behind and pull it out of the hole it's in.

If it's seriously STUCK, as in the cable will simply NOT release the knob, then you'll have to partially remove the speedo from the dash, and carefully remove the screw that attaches the Trip Odom. Cable to the Speedo back to release the cable. You'll have the speedo out of the hole with the trip cable still sticking back into the hole and then can you reach the screw.

It's much MUCH easier to say/type than it is to do, and virtually impossible to do from behind the dash.

The screw that holds the cable to the speedo is on the cable collar where it meets the speedo, and it clamps on the rod sticking out of the bottom of the speedo. They used a very small screw with a very soft head that will deform in nothing flat if you apply pressure off-axis, so be careful.

Hope this helps.

Hey Will! We both answered, but as I "putzed" around, I took longer on my reply. Geez, now Aunkie is going to be really p*ssed!

Thanks. I think I will try to pull the knob down.

I was afraid I would break it if I pulled too hard.

Thanks for the help

[MarkDixon]

Got it.

Thanks guys.

Now if I can just get all of these gauges back in when I'm done.

Thanks again,

Mark
