How much oil for a rear axle in a Ford 4600?

[Andy4600]

Ok, so I decided to change the oil in my rear axle/hydraulic system in my Ford 4600. I had not done this before, as I haven't had the tractor very long. My manual says to use 33.9 quarts of oil, and gives me a location for the oil level plug, to check level. First problem: My tractor oil level plug isn't in this location. So, I look around and find a likely candidate for a level plug, do an internet search, and confirm this is probably it.

So, I drain the old oil, which is very dark, and only get about 5 gallons out. Ok, that isn't good, but I don't know when this job was done last...if ever.

Then, I add the new oil. I bought 2 5-gal buckets of oil. I dumped in the first bucket. From the second bucket, I poured about 2 gallons into a 2 gallon container I had, and then dumped the other 3 gallons into the tractor. I figured that had me at 32 quarts, and I could then use the 2 gallons I had set aside to add the extra 2 quarts and top it off. So, I add some...and nothing comes out the level plug hole. I add more...nothing. I add more...nothing. I add all of it...nothing.

So that is 10 gallons added, or 40 quarts, and it still doesn't show full. Anyone else have this experience? Is my manual wrong? (It is definitely wrong about the level plug location.) How much oil should this thing have?

Thanks
