I had a suspected faulty alternator bearing issue on my 2003 tbird that I posted separately and it was suggested that I check out the Alternator Rattle Postings. Having now removed the alternator, it does appear that the problem is related to the alternator rattle issue.
On removing the alternator, the small bolt on the end of the shaft was loose and there was a gap of about 2mm between the washer and the drive spyder and the spyder was able to move slightly on its spline. The threads on the bolt immediately below the head, where the washers are, are damaged giving another indication that it's been moving about.
My questions relate to the washers. There are two on the small fixing bolt: one is approx 1mm thick and 14mm in dia; the other is nearer 2mm thick and is 20mm in dia. Both washers are completely flat and neither is of the bellville type. There were no signs of any broken washer inside the casing.
How many washers are there normally, including the bellville. If only two, it's possible that the previous owner has replaced the bellville with a plain washer.
Does anyone have a torque value for the bolt.
I'll need to get a new bellville washer before rebuilding.
