Ok for you oc-12 experts how much oil does my oc-12 in my 1200 hold. I drained it last night and got about 1/2 gallon out of the main box and at sun up I will drain the reduction boxes I plan on a refill with amzoil power shift oil. the stuff that came out smelled like 80-90 also had a little water contamination in it I have about 2 gallons of amzoil will that be enough or should I get a little more.

Don you mean 2100 not 1200 correct? the 1200 diff when used as the hydraulic resivoir takes 6 gallons where as the 2100 I have marked as 2-1/2 gallons
30 weight in the cold
 
next question I saw some where that the drop boxes will fill up when you fill the differential is this right. I ask this because there is a little 1/8 inch drain plug at the bottom and a half inch plug at the half way point.should I just fill through the differential or should the drop boxes be filled with 90 wt gear lube
 
also forgot to ask about vents I see none in my diff should I add a poppet vent into into the little dog leg filler pipe

The drop boxes will fill from the diff, so check the fluid after you run it, I have always overfilled the 2100 the diff on others acts as a resivor and will hold over 5 gallons so my thought always was fill it till it at least reaches the axle tubes
