Mangusta Steering wheel boss close up

Perfect!! Thanks Denis

cheers

Larry

8ma1046 a little different on the plate behind the wheel

A few more data points....no extra thin spacers on 1010, just the black base (as Denis shows) and the aluminum extender.  I always ASSUMED this was stock but always gotta wonder a bit....

That's a great close up, Thanks Nate

cheers

Does anyone know what tool is necessary to remove the hub nut under the wheel. Need to replace the turn signal switch.

An impact driver with a metric socket. Also works for removing alternator pulleys and other such things from movable shafts.

Totally agree about the impact driver. The problem is it’s a round locking nut with 4 slots.

Such sockets are called 'Pin Spanners' and they're commercially available. A larger size removes our axle nuts.

Not to intentionally distract from this discussion but is this column and parts unique to the Mangusta or are they sourced from another car?

Well been searching the last few days and still have not found a pin socket the right size. My only thought is cutting down a socket and making one.

Grainger used to carry them. One member made a rear axle nut spanner from a length of pipe with 4 slots hacksawed down its sides. 4 square lathe tool sections were brazed into the slots and a cheap 1/2" drive socket brazed into one end. Worked fine for years on the 350 ft-lbs the axle nut needs.

My guess is those parts are from Ferrari

just a rough guess

How is the size determined or how do you determine the size that you need?

This is them?

It’s definitely metric..

I would take a piece of wire, and then bend it to a U-shaped that touches the inside of the notch 180° to each other, Measure the distance with a caliper that gives you about an idea what the distance is between the pins … unless your caliper can reach in there to the nut! Drive to the nearest Ferrari dealer and ask if you can see the tool, measure it, borrow it and  leave your drivers license As collateral,  open it up at home and return it and get a normal nut.

and if they don’t let you borrow it at least you know the sizes right or not!

Or call Mr.Fiat and get the measurements.. then you know what to look for..

That nut was obviously not original…

I think those tools are manufacturer made for specific Applications…

I think it may be. See pics from my car in second post. Mangusta parts catalogue identity boss as sourced from Ferrero, nut is noted as 12x1mm ????

another hint, maybe, the Ferrari nut is 38mm  diameter . Lemans 850, I somehow remember such a nut being used on Moto Guzzi (or was it Ducati...).

Superformance has sane prices for the nut and tool...

The Ferrari steering shaft is not a  38 mm shaft… I assume the 38mm is referring to the OD of the nut…

do we have a measurement of the nut in question?

Moto Guzzi Falcone / Sahara uses a big nut like that on the fly wheel…

(in our Family since 1975)

Od is 21mm ID 18.5mm and slots are 3mm wide.

That should help.. call

...see there is a typo on the description of RNT-21 (copy and paste artifact that says that it is used with a 24mm wide nut (!)

For anyone that needs it I got this tool off Amazon https://a.co/d/7Dn6qY1

Needed to use a Dremel to trim the pins down to 3mm from 5mm. But it worked great.
