Brand new alternator! Fitted 22/06/2009.
Rode 500 km and there's a horrible noise from the motor.
I pulled the alt and it appears that the rotor has moved so far back as to allow the rear cooling fan to contact the diffuser in front of the rectifier plate, and the drive coupling has rubbed against the front cover with enough friction to burn the new damper rubbers. Even the drive coupling has turned blue from the heat.
The old alternator was also damaged in this fashion but the PO mentioned having had the alt repaired.
Is it possible that the drive coupling in the motor is forcing the rotor back while under load? When installing the alternator I managed to move it fully home without having to use the bolts to seat it so I know there is no force there while the motor is not running.
I have searched the forum and have not come across anyone else experiencing this problem.
Honda tells me there is no guarantee on electrical parts but I will nevertheless contact them and see what they have to say. This alt has after all, only done 500 km.
I e-mailed Honda South Africa and they asked me to bring the alt in for inspection. They sent it to Boschand after about 2 weeks informed me that it was a factory fault and they would replace the unit. (They couldn't tell me exactly what the fault was).
I collected the new unit on Friday and fitted it. If this rotor also moves back I doubt Honda will replace the alt again.
Has anyone else experienced this problem? Is something forcing the rotor back? Apart from checking clearances every now and then, I don't know what to do. I can't have the only Wing in the world that does this to alternators, can I?
