HOW GEAR OIL?

[JD1973]

How many quarts of gear oil is needed to fill a 12bolt rear end with the B&M cover on it?

Until it starts oozing from the fill hole on a level surface.

Idk how much the aftermarket cover holds but it’s just shy of 2 qts for a 12 bolt stock cover.

I JUST drained and filled mine two weeks ago, with the B&M cover. It took a gallon and a half

Ok. You just exist to argue with people, don't you? That's pretty much I ever see you doing on here, is replying to threads to argue about the dumbest stuff. Do you not have anything better to do?

There is no way a 12 bolt chevy,took a gallon and a half on a refill. I wanted to make sure the O.P got accurate information.

The B&M cover is designed to hold way more fluid than stock. It butt's out further and the fill port is much higher up

O.P. I'm going to say just a shade under 3 quarts, please let us know. Thanks

Not wanting to stir the pot, but just clear things up.

Pretty straightforward to check into…
Says the b&m cover adds 1/2 quart capacity.

What are the chances you put in 3 bottles of gear lube. Now if you were thinking the bottles were 1/2 gallon I could understand you thinking you put in a gallon and a half. The bottles are quarts. Also what are the chances you filled it until oil ran out the hole in the rearend cover? You are only supposed to fill it until it runs out the axle housing fill port,then stop filling and replace both fill plugs. If you didn't do that it will allow you to grossly overfill it.

If you call having years of knowledge, and then sharing said knowledge with forum members, as being argumentative, then yep he argues with everyone. I personally enjoy him sharing his knowledge. @Ricko1966 Please keep sharing your knowledge.

The fill plug on those covers are not to be used as a level plug. The original fill/level plug is to be removed, and filled until fluid comes out of the hole in the housing, not the cover.
