Ford 640 Generator Lube

The Ford manual states to oil the unit's bearings, but I cannot find any oil port on the 6 volt generator on my Ford 640. Were some Ford generators permanently lubricated?
 
No, but who knows how your generator has been modified in the last 60 years.

The OEM gewnerators had an oil cup on the commutator end of the housing. A couple of drops of oil 2 or 3 times each year is sufficient to oil the bushing.

There was no oil cup on the pulley end for the OEM shielded bearing. I put sealed bearings in the generators that I overhaul.

the generator on my 2000 has what looks like a pressed in ball bearing on the rear housing. if you push on the bearing it is spring loaded and you can use an oil can to lube the rear bearing. the front or dive bearing must be sealed. on mine anyway.
 
Never seen a 4 cylinder vintage Ford gasoline tractor with a generator having anythng but a bronze bushinig in the commutator end frame.

Would like to see photos.

ean, I don't think he is saying ball bearing at commutator end, but rather that the little circle at rear in the attached picture is a "ball" with a spring under it. Push it down with spout of oil can to oil the bushing and when spout is removed, it self closes the opening. I personally have seen some hundred series generators with zero provision for oiling.

Thought so.

It has a bushing on the commutator end.

Two or three drops of oil in the oiler about twice each year is more than enough if all else is good.
