Spacing your alternator to make the belt line up



If you bolt your punto alternator onto the stilo 1.4 engine you will notice that the pulleys do not line up. To alter this i made spacers from the stilo engine mount that i took off of the engine previously. If you do not have this something will need to be fabricated. You need to make 3 spacers exactly the same width. Mine are roughly 27mm but double check they line up nicely when the alternator is in place.

Allowing the alternator belt to clear the engine mount
To do it properly take the engine mount to an engineering shop and have a 5mm spacer made up for the flat side of the mount that bolts to the engine. This spaces the mount out slightly, but not enough to make it impossible to connect the other 2 mounts later, although it is slightly harder. Alternatively you could make something similar.
While the alternator is in place, bolt the engine mount onto the side of the engine. With the cinquecento alternator belt, check that it can rotate freely, if not continue to grind the mount.

I would personally leave the alternator to one side until the engine is in place as it makes things easier.


With the engine mount now finished i would take this opportunity to fill the mounts full of silkaflex or similar. These take a couple of days depending on brand to set so be prepared for that. Not pretty, but does the job very well.
