There have been reports by people on here having trouble with hubs for the Nardi. The two reported symptoms are:
- horn not working
- too close to the stalk - particularly for the flashers to work
Wife got me the v expensive NOS wheel and the collapsible (MOMO) hub. This has a rubber gator around it. The hub will not work:
- it needs to be about an inch deeper (so wheel further from dash) for the flasher stalk to work properly. In current guise it hits the rim of the wheel before the headlights come on AND
- the female part of the spline (male part being the steering column itself) sits too proud of the brass horn contact rings at the car end.
Thus the hub fits perfectly from an aesthetic point of view - diameters etc, but is not the righht hub for a 280, certainly
I am in process of trying to change out the hub (fingers crossed). In essence, I think you want the longer, non-collapsible hub: mine is 3"/76mm (Stock is about half as much again)
FYI - to get the steering wheel off the spline takes a 23mm socket. I couldn't find that on site anywhere
The wheel looks fantastic and this is not a criticism of the seller as clearly others have had similar issues in going to a Nardi. Of course, if I do get the hubs swapped, and I have the same issues, I really will be lost! I grabbed some photos from the Wood-Steering-Wheel lady on ebay to show what I think the differences are. Top is the collapsible hub that I have, bottom is the other type which appears to be longer (and shallower for the horn contacts)
I gather that on the hub the distance from top of spline to brass contact rings is:
- Collapsible hub 0.305"/7.75mm
- Nardi original hub 0.23"/5.8mm
- Stock MB hub 0.14"/3.55mm
So effectively I have doubled my distance between brass contact rings and the horn pins in the steering column
