Changing hydraulic oil in 460

Posted by Rich_WI on December 28, 2010 at 00:10:17 from (71.98.24.189):

My job this week is to change the milky hy-tran in my 460. Im hitting a few problems. First off, I pulled the huge plug under the axle but I only got 5-6 gallons out, does that sound right? I thought I was going to get 10 or 15. I just checked the side check plug a week or so ago and it was only 1/2 inch down so I know it was full. I thought that plug would empty the whole thing.

Then I saw another plug about half way between the huge drain plug and engine oil pan, pointing toward the front of the tractor. I pulled that one and only got another gallon or so. Does that sound about right?

Last, I saw one more plug just behind the engine oil pan. Its a plug in a small plate thats maybe 4 inches by 7 inches with IIRC 6 or 8 bolts that hold it on the cast iron. Well I tried to take out that plug and stripped the head off. Whats under that plate? Im thinking I should pull the plate off and get out the plug while the $100 of oil is still in the sealed buckets instead of the tractor. I dont want to tear into that plate though if there is anything that I can mess up under the plate. Im kinda on a time schedule and want to finish this up on Wednesday if I can because the weather is due to turn here in Wisconsin after that.

I looked in the very back of the tractor by the PTO to see if there was a drain plug there but didnt see anything, am I missing anything or is there no drain back there? I want to get as much of the milky oil out as I reasonably can because I cant afford to do this again any time soon.
