took my standard 500 engine to bits today to rebuild it but got stuck once it came to taking off the crankshaft pulley? removed the 6 bolts on the front face then couldn't get it off. Is it just them bolts that hold it on?

Hi Garf

I am not sure if you are refering to the pulley that incorporates the centrifugal oil filter?

If so, take a look here: http://members.lycos.nl/dm5675/haynes/Haynes_UK.htm

and refer to section 1.8 which covers removal of the pulley.

Long time since I worked on these engines but I seem to remember there was a small lug on the aluminium centrifugal oil filter cover that provides enough space between the cover and the crankshaft pulley to get a screwdriver in to lever it off.

If any of you '500' guys haven't got it already, here's a link to the original Fiat 500 repair data manual. It's in Italian but may be useful.

Thanks Dave!

Even without understanding the Italian text there are some good sectional diagrams there!

seem to remember thinking this oil filter doesn't work very well untill I realised that some of the alluminium was dirt and needed a stanley knife to cut it out, was pretty impressed after that!!! the exchange crank was about £6. 10 bob then then I was REALLY impressed about 1970
