Alternator FULL of OIL!!! What went wrong?
Posted: Sat Oct 27, 2012 9:43 pm
'82 SD22. My alternator went out the other day. Pulled it off and it is full of motor oil.
There are no signs of oil leaks outside vacuum pump.
I pulled the vacuum pump, and it looks like it came into the alternator via the alternator spindle shaft.
Where is the seal that keeps oil out of the alternator? Inside the alt. behind the spindle shaft or inside the vacuum pump?
I have a rebuilt alternator on hand but I don't want to throw that in if the vacuum pump is the culprit.
Also, any microfiche on the vacuum pump?
Any help is much appreciated.
