how much grease do they hold its the eaton h052.
we had to put 6qts in it one time but it i dont think it was empty then
were putting it back together and cant get the fill plug out.so were going to install one axle and then jack the othe side up and pour grease thru axle tube.

So you're talking about filling up a eaton posi rear end right?
I have a 12 bolt eaton posi 3.73 and it required 2 1/2 to 3 quarts of 85/90 weight gear oil.
6 sounds like a lot unless I'm missing something.
Good luck,
B

this is actuallay a eaton rear 3/4 ton 4x4 rear this thing is huge

This rear is a full floating axle and has the big round 10 bolt cover, almost looks like a big truck axle. I don't know exactly how much it holds, but the easy way to know when it's full is to put gear oil in it till the level is just below the fill plug hole. Now since the plug is stuck I don't think that method will work.

6 pints for an eaton 10 bolt. Another way to fill is to remove a cover bolt at the same level as the drain plug. You can squirt warm oil in that way. Put the bolt back in with sealant.

Fred hit the nail on the head.What I`ve done in your situation is,put 6qts in the axle tube,then remove the cover bolt at the plug-line to let extra lube out.It`s just a bit quicker.

I gotta stay outta these 4x4 3/4 ton threads!
hehehehehehehehe
