9000 rpm tach

i admire your rims men what size are they?

I remember when I had one apart I had a look a the time, if you check this pic



The tach slots into the plastic housing so you cant get the whole assembly and rotate it as it wont fit in the housing.

Nicest way would be to make a fascia like David has so that the numbers are the right way up and repos the needle.

Interesting about the E36, a few E46 cluster transplants getting around now too

oh, I think you could do that. might have to deal with some mounting issues, but I don't see why you couldn't.

regarding tachs - it's exactly the same as the E36 tach. I rebuilt mine using the motor from an E36 cluster (as well as the econometer) when the tiny spring assembly in there exploded into a million peices, never to be put together the same way again. Actually the entire cluster is basically the same, except the SI board is intergrated, and the odometer electronic instead of electromechanical. I bet you could swap an entire E36 cluster without too much work.

What I meant is rather than having to change fascias like David has, just spin the whole tach assembly like you can in Porsche's with the old VDO gauges.

Ive found a few pics of others who have done the new fascia and needle repos, but econo gauge delete would satisfy me

[nando]

I wish we could spin the tach around so that redline/max rpm is at TDC but it would involve major surgery or after market,


I think it looks great

No it wouldn't. All you'd have to do is turn the needle and move the stop.

Also interested in a custom E36 one.

dsm, can you do an E36 one to 9500rpm please? and how much?

I'd appreciate it if you ask this James of whom you speak next time you see him and post how he did it (if it is not a secret!).
TIA

It's James Criv.
He owns this forum :)
I'll ask when I see him next.

I think we rotated the whole tach. I'm not completely sure; James did it.

Cat just rotate it because of the way it fits into the housing unless you guys get a different cluster to us but wouldnt think so.

As mentioned, maybe needle repos

9k you are my hero.

It's easy to rotate. We did it in our track car.

Did you rotate the whole tach? How did you arrange this with the circuit board and pins? ... or did you just reposition the needle?

[frankenbeemer]

You can't just reposition the needle?

[KenC]

Like this?

I have spoken to an instrument tech and it'd be possible to rotate the tach but it'd take a bit of surgery.
