Technical Steewheels- removing the two pins on the hub?

[JorgenG]

Can anyone tell me if the two pins on the wheelhub only are for the original steelwheels?

I want to change wheels but do I need to find rims that has those two holes?

i suspect they can be removed, but will the whole wheelhub open up then?
What would be the best way in that case to get them off? I tried with a wrench but since the the hub turns as well its difficult

Any help appreciated Cant find any info online

Pointed bolts are to stop the disc or brake drum coming loose from the hub when wheel is off. Plus to help align the wheel when fitting. If the disc comes loose when wheel removed dirt/rust can drop between the disc and hub causing dangerous disc run out.

Fiat wheels of either steel or alloy fit with the screws in place.

Do not fit any old wheels you find , the spacing of the wheel bolt holes is safety critical.
The hole diameter in the centre of the wheel is important too.

Leave the disc / drum pointed bolts alone.

Both my classic Pandas had only one pointed bolt on each drum or disc, with a setscrew in the other hole, but with a very thin head. This is an option if the wheels have clearance behind at those points. No idea if the original Fiat srews are still available, but a standard screw with the head reduced will work, but once ground or filed will rust quickly, so will need coating.

Better to get wheels with holes. The pointy studs do help a lot with alignment when refitting a wheel. I have replaced wheels on a lot of cars without those, and aligning the wheelbolt holes is a pain.
If you have to go without pointy studs, consider getting a spare wheelbolt, and taking the head off it to create a stud. When refitting a wheel, this stud will help alignment and sitting the wheel on while another bolt is fitted. Keep it in the car toolkit for those wet winter nights and a puncture.

Thanks a lot for your answers
The thing is that I want to get the whhels refurbished and I have borrowed 4 wheels the same size but no such holes. The car will not be driven during the time the wheels are off, but I guess its not a good idea then.

I thought yu could unscrew the bolts so that the other wheels would fit but if the brakes opens up I wouldnt take that chance.
Well well

If you are not going to drive it and the bolt holes for the wheel bolts are the correct spacing so will fit your hubs- use a hack saw and cut the points off just above the hexagonal part a spanner fits on.

Then you will have sufficient room to fit the wheels
You only need to do one side if you have a spare wheel in the boot.

I fitted Alfa Romeo wheels on mine , I left the hub pins in place although

the Alfa rims didn't have holes for them and the pins were in a large gap

on the inside of the wheel .

The pins just held the discs in place on the hub .

I also used much longer wheel bolts bought off Ebay and they were caused no

issues for a few years and many miles .

Newer Fiat’s did away with the pins and replaced with counter sunk screws with a torq head.

If you’re just fitting the other wheels and not using the car while your normal wheels are refurbished then you’re going to be bolting the temporary wheels on tightly it’s not going to do any harm to remove the pins for a short time and put them back when you get your normal wheels back from being refurbished.

When it comes to removing the pins, if they are a bit rusted in place then yes they can be hard to remove and can round off if you’re not careful. Usually when doing this it’s to replace the brakes, rear ones are easy as the hand brake should hold them and stop them spinning. Front ones I would hammer a screwdriver into the vents on the disc if they’re being stubborn but if you want to reuse the disc again which I assume you do, put a couple of wheel bolts back in and and use a long bar to brace the disc/hub still while you remove the studs, or if you have another person sit them in the driver seat to press the brakes
