Technical Need help disassemble my punto alternator.

[mechtech]

Hello guys..
My punto s60 alternator starts to make noise, I want to disassemble it and replace the noisy bearings.
I saw the Seicento guide and I'm looking for punto guide.
What is the exact tools that I need for this job and do I need to work beneath the car and disassemble the plastic inner wheel arch covers?

Thank you in advance.

The Punto one is pretty much identical (they all are, really, internally). Bear in miond that more than the bearings may be worn out.

I'd think that on a Punto you may have enough room to get to it without removing the wheel arch liner.

H & S warning!

Disconnect the battery negative terminal (and poke it well out of the way) before you do anything.

if the bearings are making a noise then your commutator and brushes are bound to be worn too so changing the bearings which i am fairly certain you cant do and certainly not while its fixed to the car would be an unworthwhile exercise
i changed a punto alternator this week for a bearing noise but it wasnt till i had it on the bench and spun it by hand that you could actually feel the rough bearing
i replaced with a good second hand one from my bat cave,job done

i did put the upper bolt to the block in first then found the lower bolt wouldnt go in and it took me ages to figure out? i had once again used the wrong upper engine hole:bang:

Is there a repair kit for this alternator?
E.g. regulator and brushes, rectifier and bearings.
Does this job can be done in DIY method, or it's not worth it?
What's the difficult part need to do, do I need special tool to open the rotor nut like pneumatic hammer, or an extractor tool to pull out the bearings?
I want to do it the cheapest way.

Cheapest way is to find a small, local, alternator and starter motor specialist who will rebuild your alternator.

If you think about it, this guy can get bearings and parts at trade. He has the tooling to pull your alternator to bits, the tools to measure components for wear, the equipment to run it up to speed off the car and test the output. Years of experience and wisdom. My local one is called Barry, but that's probably of no use to you........

I've yet to come across a modern FIAT alternator which didn't have a cap head socket on the shaft. Getting an ordinary socket on the end of the nut can be a problem, though.

The heat spanner (and sharp tap) is the easiest way to remove bearings.
