Momo Steering Wheel Install, Illustrated

[Cattler]

Well, there's the horn button and then the black bolts fastening the wheel to the hub.

I'm going to try to fix this wheel alignment issue this afternoon. What's the best thread desribing the tie rod end adjustment to center up the steering wheel? Never done that and don't want to screw it up.

I just did that here (unsuccessfully at first): http://forums.pelicanparts.com/showthread.php?t=483244 I was trying to do it by turning the tie rod ends. That didn't work too well!

There is a slot on the tie rod for a box end wrench, and a similar slot on the tie rod end to keep it from turning while you turn the tie rod. Just loosen the lock nut while holding the tie rod end, then rotate the tie rod. Don't forget to re-tighten the lock nut. Repeat procedure in the opposite direction on the other side.

In the end, it took about a 1/4 turn of the tie rod to center my wheel, which was off by 6 degrees.

Thanks. I just moved it one spline to the left and its pretty good--really, really close. Now, it's cocked a bit to the left when the steering wheel lock is engaged, but I think I can cope with that.

I might try to tweak the tie rods--thanks for the link to the other thread--but I'm going to wait until I drive it for a while to get used to the smaller diameter and different look of the wheel. Now that its close, I'm not sure that the remaining "off-angle" isn't in my head.

You could also lower one side of the front of the car; Probably the left, and I mean just a little. Won't affect your alignment enough to worry about it, and will in fact straighten your wheel a bit. I know because I did it. Might only take a 1/2 turn of the srew, maybe less; not enough to affect things.......... I think.............I am willing to stand corrected.
If you adjust a previously good alignment at all, take notes of all so you can undo things and get back to where you started. All I know is it worked for me with no ill effects, and I have put a lot of miles on lately, with great straight ahead tracking and no unusual wear. Just slight adjustment, though.

I'd fine-tune with the tie rods. Lowering a tad may not seem to have affected the alignment, but it certainly will change your corner balance.

Great guide, thanks. I just used it to fit a new Prototipo to my 75 Targa, and can't believe the difference it makes!

Newbie question...at what angle do you place the turn signal cancel. I took the old one off without checking the angle. Is it straight up?

[pegasus9]

The turn signal cancel tab sits at around 9 o'clock iirc. Get it around there and you should see where the 3 screws line up.

Those Momos are great.

If any reader here fancys one, check my ad in the classifieds:

cool thx, black pegasus, makes sense.

[whiteNSXs]

Thanks for the write-up. Of course the Momo hub that I got came with no instruction manual hence my search on this topic and found this. What is also so odd that this hub comes with no cancel tab so either buy a new one or transplant the stock one from the stock wheel. As far as I know, most momo hubs come with the cancel tab including the hub for 928. It makes no sense at all.
Also, has Momo ever included the installation instructions at all or it was just mine missing from the package?
Thanks,
Steve

Great write up! Helped me get my vintage Momo installed in about 45 minutes.




Rarely am I not posting from my phone....

I wanted to say thanks for posting this bit of knowledge. It's what makes the PP website so useful. The info definitely kept the job simple. I managed to get my old bus steering wheel off and the new one on in under an hours time and that included the trip to Sears to get a 27mm socket. Here's where I hope to add to the knowledge imparted. I had a 1-1/6" socket in my collection, but couldn't get it through the hole as it was slightly too large (approx 38mm in dia.). If you need to buy a new socket for this job it should be no larger than about 35.5mm to squeeze into the opening. Otherwise you will have to get out the grinder. I still need to find some countersunk screws, but the button-heads will work for now. How long will the stiching stay so white and clean?

On another related topic. It's so sad about Sears. They didn't have a normal 27mm, just deep. The selection is way down from the old days. No customers. I wonder how much longer they will be in business?

I know this is an old thread but wanted to say thanks - my Momo adapter didn't come with any instructions so I didn't know where to start. This thread explained it all and was able to get it all done in about an hour.

Looks so good! I’m waiting on a spacer and gaining knowledge regarding the horn button wiring and can’t wait to do this install!!

dangerous! the risk of damaging the lock is too high!

use a piece of wood 2x4 and use it to secure the steering against rotating.
tuck top wood under the bar of steering wheel and tuck it solid into the floor.

cheap, safe and easy.

I am planning to be more rigorous in using a torque wrench when tighting nuts and bolts on all jobs I am doing. What is the best source for a reference on the correct Nm on a 911? The PET has no info...

[Flojo]

The booklet says 80Nm if I'm not wrong from memory

For the wheel nut is 80nm? I thought it was 50 or 36 ft-lb.

Thx

[kenjib310]

Any one else have a small, say 3mm gap between the plastic around the steering column and the momo hub?
