SOT: 930 Tach disassembly FT! is rattling in there?, Unless your running a boosted -6 Options

[914forme]

So I have a 930 Tach, and every time you rolled it around it would rattle. I figured that someone dropped a bulb in it, but before I did something with itI needed to find out why it rattled so.

So let the autopsy begin. (IMG:style_emoticons/default/screwy.gif)

930 Tach - so what makes these so damn expensive (IMG:style_emoticons/default/confused24.gif) That little 1 bar boost gauge hosed in the face. (IMG:style_emoticons/default/confused24.gif)



Tools of the trade - custom made for this job.



Opens gauge bezels like a can opener.



Just work your way around, at least 3/4 of the way.

Flip it over remove three screws and one nut.



And removed from the can

Well, here is the real skinny on this.

The boost gauge portion is not broke, it goes full right with out a resistance source. That is a big plus. So it is working as intended.

930 parts carry a cult status with them. I completely understand why, but just saying for what it is it is not that big of a deal. (IMG:style_emoticons/default/confused24.gif) Certainly not worth the $$$.$$ being offered on Ebay for (IMG:style_emoticons/default/ar15.gif)

Yes you can add a fuel gauge movement to the tach with the help of some friends. You can do it with a stock face plate and some carful drilling. and then a couple of tick marks, a vinyl stencil would most likely do the trick. and then a bit of 1 shot and a nice brush. Or 1 shot and an airbrush. Add a small spot for the low fuel warning light to go, and well you got a working gauge. And a very nice trick combo gauge.

Mark what are you running that you need more gauges?
Speedo
Tach - add 1
and a Quad or Triple gauge.
With the Quad you can have 5 (other) gauges, that is a lot of gauges.

My 914-6
Oil temp / Pressure, and fuel.
Guess I could add cylinder head temp or two for both banks and move the fuel over to the Tach. Quad is easily made via a 924 combo gauge.

? - but if I use the 930 tach, then I would keep it a 930 tach and add positive pressure to the intake side. (IMG:style_emoticons/default/happy11.gif)
