I have an X-reg Renault Megane (1.6L 16V).
yesterday I had to stop when the battery warning light came on. Opening the bonnet, it turned out that the pulley had detached itself from the alternator, and was lying at the side. The friendly breakdown chap said it wasn't meant to come apart, and a new alternator was called for.
I don't like to doubt his word, but since the alternator spindle and the inside of the pulley (well, the black sleeve inside the pulley) are threaded, it looks very like they are made separately and just screw together.
I got myself a copy of Haynes, hoping for a fully expanded diagram (as there had been in the old Volvo manual I had a few years back), but no.
So the question is : should it be a simple job to reattach the pulley to the alternator, or is it indeed knackered ?
The outside of the black sleeve has a large hexagonal insert, sugesting that an enormous (3cm) allan key be used to tighten it - how do I lock the alternator while tighening it. OTOH, there seems to be the impression of a washer at the base of the hexagonal inset, suggesting perhaps an additional nut holding the pulley to the alternator. There's a diagram in Haynes : 1A.18.18a, but it's hard to tell from that :-(
Oh - car has AC and PAS - I believe that affects the layout of the alternator belt.
TIA in advance for any suggestions.
