Alpha 1 Gen 2 repair

[stevekw_3]

Got a '91 Alpha one. After initial spring start up I had milky oil in the driveshaft bellows. I pulled drive off, drained oil. I pressure tested at the upper vent hole. 10 lbs of air, ran out immediately thru the driveshaft u joint area. Is there a seal in the bearing carrier of that drive bearing, or does that just seal with the big o rings? Also, do I need to pressure check at the drain hole in lower half to check for leaks down there as well? Thanks for any help.

Ok I guess I should've read the sticky at the top before I asked. Lots of great info in there.

If by milky you mean mixed with water in the bellows, then you have a dual problem, both a water leak and a separate oil leak.

It was definitely mixed with water. I had the hose muffs on while running it, and milky water/oil started oozing out from bellows. I plan to replace all the bellows while its apart because I was getting some water in them after being on lake. What would be leaking water while running it with muffs?

There is no water line in the u joint bellows Chances are you're seeing an oil leak. The water is coming from a split in the bellows itself and it's probably built up and coming out as new oil is introduced from running it on muffs.

It is possible for water to get into the bellows when running on muffs if the water passage o-ring is bad, mis-located or broken. When that o-ring isn't sealing then water can go from pump, into shifter cavity and from there into the bellows.
