Alternator


Hi
We are in the process of replacing an alternator.
Is there a way to pin it so it doesn’t move so you can remove the gear or is there a special wrench for this .
Thank you,

The large thrust washer under the nut must be replaced when installing drive hub on new alternator.

Excellent point, Bob. All the good information like this is in the M&O Standard Practices Manual.

Hi Bob,
Do you have a part # for the large thrust washer and where I might find one ?
Have a nice evening,
Tim

Hi Bob,
Please find a picture of the alternator we are replacing.
It’s an overhauled alternator with 66 hours .
I got a red alternator light and wasn’t able to reset it.
It turned out the 3 amp fuse blew at the firewall.
What would cause the case screws to be loose ?

Washer P/N is 658715 at Aircraft Spruce.
I would send it back to Aerotech since they overhauled it very recently.
The RED alternator out light only indicates that the AUX winding has no voltage output or the alternator has failed.
If RED light illuminates check the ammeter and if alternator is still providing output flight can continue.
