Quick question on 4000 hydraulic resevoir

When I bought my 69 4000 and drained the oil from the rear end and a bunch of water and a bunch of oil out of it. I overfilled my drain buckets and made such a big mess on the shop floor. I read on tractordata.com the hydraulics take 8.4 gallons so that's what I put in mine and everything seems to work ok.

Today my neighbor called wondering how much oil his 4000 takes in the hydraulics. He said he drained out about 12 gallons of oil and it was really clean looking oil..no water or milkyness. His tractor is a 1966-67 we think.

So what is the correct amount of hydraulic oil these beasts should take? Both of our tractors don't have a side level plug like we're used to seeing

41014E and D1014E are both diesel 4000's with Select-O-Speed transmission and 540 rpm independent PTO.

8A22B is January 22 1968 day shift.

9K30B is October 30 1969 day shift.

The 1968's S/N starting with an A means it was assembled at the plant in Antwerp Belgium.

The 1969's S/N starting with a C means it was assembled at the US plant.

According to my owner's manual, the rear axle/hydraulic sump should take 33.9 quarts, which is roughly 8.4 gallons. They can be overfilled by quite a bit without causing any real damage, it just doesn't help much to add more than the recommended amount unless you are running external cylinders off of a remote or a hydraulic adapter plate.

I have a '73 gasoline 4000 with the S-O-S and the level check plug is there, but it's not where the pictures in the owner's manual says it should be because it doesn't have the gear pump in the right side of the center housing with the S-O-S. The plug is a square headed plug and it 's farther back than a non-S-O-S 4000 and almost directly behind the footrest so you can't really get to it without removing the footrest. I measure how far down it is from the fill plug and use an extra large nylon zip tie as a dipstick to get it close. I figure if the zip tie has to bend around the axle or side of the differential to get down there then it's probably a little higher than it needs to be, but not too much over full.
 
Destroked, Thanks for the correction. I think I was starting to fall asleep when I wrote that. I'm surprised I got the rest right. :D
