This afternoon I removed the alternator from the engine, which is currently mounted on the engine stand. The alternator is mounted to the front of the engine block on the driver's side. It's pulley is driven by the fan belt.
Towards the top the alternator is mounted by a bolt through a slotted bracket. This allows you to mount the belt on the pulley and then swing the alternator outward until the belt is tight, and then tighten down the upper bolt to fix the alternator in position. I loosened this bolt using a 1/2" socket.
The alternator is mounted at the bottom by a long bolt that threads through a knuckle and holds the alternator to the block. I loosened this bolt using a 9/16" socket. With the bolt broken loose I was able to rotate the alternator upwards and towards the block, which provided enough slack to slip the belt of the alternator pulley.
Then I removed the lower bolt the rest of the way. I rotated the alternator downward on the mounting knuckle and then slid it off the block.
With the alternator removed I gathered it and the starter, which I removed when I
pulled the transmission, and took them both outside to clean them up.
I wiped down the starter and alternator to remove as much grease as I could. I plan to take both out to a local place and have them rebuilt. They are both nearly 40 years old, after all. After that I will clean them up further.
