Momo Hub, Momo Hub for Early '73 2.0-S Options

[raynekat]

Momo 8000 hub attached to my Momo Prototipo.

[raynekat]

This is the type of Momo horn button I have.
Has the 2 electrical connections and the spring that holds the button
into the hub does not contact the inside of the hub.



Apparently, this is the type of Momo horn button I need.
The spring that does contact the inside of the hub completes the circuit when you push the button.
Why is life so complicated at times?
Makes it a challenge to get the button you really want (how it looks) vs getting a button that actually is functional...but maybe not your favorite as far as looks go.

wow 8000 where you just lucky or is there a source??
now if you can find the marker lens (IMG:style_emoticons/default/beerchug.gif)

this is one I have for comparison. Looks the same but numbers are different. (IMG:style_emoticons/default/confused24.gif) I

No source for the Momo 8000.
Just an answered prayer I guess.
Put a WTB on the Early S Registry and someone had one.
Pricy bugger, but what are you going to do?
Not many other options if you want to run a Momo steering wheel.

Was almost going to go get a Nardi hub and a Nardi-to-Momo adapter.
Didn't need to in the end.


And yes.......that dang Italian marker lens.
It's still a thorn in my side.
I'm not giving up yet on that one.

Gave up on the Luisi hub.
It's not going to fit my 71 914-4 although the shop that sells them swears they've sold a lot of these and no one has ever had a problem? What?

Fast forword to today....
I bit the bullet, found and purchased a Momo 8000.
It fits great out of the box.
It was necessary to tap the 3 holes on the backside where the turn signal cancellation ring fits.
Done.
My only issue was trying to ground the horn button to the inside of the hub.
The Momo horn button I had in hand had 2 electrical connectors.
The Momo 8000 hub has one wire.
Something doesn't translate here.
For now I just snuck a wire underneath the large washer/nut that holds the steering wheel on.
Put that wire on one of the horn button connectors and the wire from the hub to the other horn button connector.
We have a horn.

How have other people completed the circuit for the Momo horn button?

I did exactly as you did. I just snuck the wire under the large washer and put the nut on. I figured I'd feel it if the nut started getting loose. That never happened and I recently went back to the factory steering wheel.

Guess I never paid much attention to all of the steering wheels between early and late. But wouldn't it have been easier to just put one of the late canceling rings on the Luisi hub? Or for that matter, the early factory wheel?

By the way, there is a guy (in Mexico, maybe?) that makes small patches of leather with the Porsche logo embossed on them. They're designed to fit the Momo horn button. If you get one you may have to flatten' the copper or brass cone inside the horn button in order for the leather piece to have enough room to 'float' above the contact.

The main problem with the Luisi is that the spring loaded horn contact pin in their hub does not line up correctly with the Porsche factory copper horn contact ring that is in the steering column. It was going to be a major deal to get that sorted. There were enough other issues that just didn't make it worth the while. Momo horn button was too small for the Luisi hub, the factory turn signal cancellation ring does screw on the back of the Luisi hub...but it's clocked incorrectly. Just enough issues to make it unusable in the end...at least to me. Perhaps there are clever fabricators here that could have made that Luisi work; just not me.

So I cancelled may 8002 order with Pelican, and ordered up the hub from classic garage.

I have a hub from Max Papis that appears to be correct for early cars.
I will try it on a friend early car.
I contacted them when I saw Pelican is now carrying them. I told them them appear to have a hub for the early cars but the cataloging was not correct. They sent me two hubs to verify fitment.

The hub you have looks like a momo 230 that fts 914-6 and early 911..
I just happen to have sitting next to me (IMG:style_emoticons/default/idea.gif)

those crazy Italians Gianpiero Moretti for instance. “Ah, Moretti used to make the best spaghetti sauce.

[raynekat]

Bruce, your hub will not fit an early 914-4.
It will fit a 914-6.
They have totally different hubs.
The 914-6 takes a Mom0 0230 hub which what yours look like.

The hub for the early 914-4 needs to have a substantial recess like this:



Excuse my French....but your back of your hub protrudes. (IMG:style_emoticons/default/wink.gif)

I think you are correct on the fitment. I have a SWB column it should fit. Will cross check the Momo 230 fitment.

[raynekat]

I think the Momo 0230 hubs fit not only the 914-6, but 74+ 911, 924 and 944. Plus some others as well I believe.

.230=73 - 911

Update from Luisi.

I sent my first Luisi hub back to the vendor I purchased it from today, as I just received a new and improved version of the Luisi hub for early (70/71) 914-4's.

It looks like a winner.
Fits great, the horn contact pin is in the correct location, takes a Momo or Nardi wheel.
And price is great.
They are normally $85.98 which is a whole heck of a lot cheaper than any Momo 8000 you'll be able to find....but they are currently on sale for only $65.98.
That is a screaming deal.
The vendor has been great to work with and very responsive in finding a solution to getting my Momo wheel installed in my 1970 914-4.

I'm trying to find out right now if this is a wheel hub they can easily stock, or if it was a special order, one-off kind of thing they did for me.
I'll get back with everyone on this as soon as I hear back from them.

[sixnotfour]

Super Good IIntell…..great vendor response...

[raynekat]

So the vendor is sourcing this new design from Luisi now.
It is very similar to the Momo 8000....for the early (70/71) 914-4.

Classic Garage is the place.
I think total including shipping is right at $85, so a very nice price.
Not affiliated.
They just went out of their way...a lot...to help me out.

As far as horn buttons go....
There is a supplied ring that can be used, but I think a standard Momo button may still be too small.
I've got a horn button I bought from Car-Bone out of Poland that fits nicely with a little foam tape on the edge of it inside of the supplied ring.
I'm sure you creative guys out there can figure something out.

Otherwise, everything else fits as it should.
The stock cancellation rings mounts up easily.
The horn contact pin is in the correct location.
The splines are correct.
And there is the right amount of recess on the backside of the hub to meet up with the steering column with a small gap between the two (the hub and the column).

I'll try to get a pic of this hub up on this thread by tomorrow.
