D3 Leaks

I have an old Cat D3 out at my place where I'm working on a pond. It belongs to a friend and isn't costing me anything to use. The old dozer is very powerful and runs great, but it leaks fluid from several places. I'd like to try to stop the one major leak that is in the main transmission hydraulic system, the others aren't that bad and I can live with them. The transmission sytem will use about 5 gallons of fluid in 5 or 6 hours operation, it leaves a trail sometimes.
I took the floor plate off and inspected the lines on the back and top of the transmission and it isn't leaking there. I can look down under and behind the engine from the right side of the tractor and see two large hoses that go into the radiator (oil cooler) and the bottom plate covered with a pool of fluid. The leak must be back under the transmission where I can't see it. Can I take that big bottom plate off to get to the hoses? How much does it weigh? Can I run the tracks up on something on each side so I can get under there to work? Thought I'd try to do it myself. Also battery doesn't seem to charge, the meter says charging when it is running. There is a plug on the right side behind the fuel filter, the plastic part is broken off, it has wires attached, what does that do? I can't just take it to a shop, would cost a fortune as everything about the machine looks worn out.
Any suggestions on how to get to this leak would be appreciated.
Buck

Thanks for the tips and information. I've been working since I posted the first time and haven't been able to get out there to work on the D3. I'm off a couple of days next weekend and plan on scraping a little depression in the dirt to straddle with the tracks so I can work under the dozer. I'll use a piece of plywood to lay on and I have a heavy board to put a floor jack on. I think I can remove the bolts that hold the bottom plate on and lower it and drag it out of the way. I hope I find a hose leaking that I can replace or maybe just tighten up.
Anyway, thanks for the help and I'll let you know.
Buck

Hi Buck, your heading in the right direction.
Get the tracks up a little so you can get under it. It would be nice if you have a concrete floor to work on too. Use a small floor jack to lower the rear pan, the rear will come down first, when the edges get below the bevelgear case you can pull it back and the front will fall. Dig out the mud and start looking for what is leaking. There are some small steel hyd lines in there likely one of them.
Good luck Bob

The skid plate on the bottom underneath the trany is easy to get off, but very hard to get back on. It will weigh around 100 lbs depending on how much grease and leaves are built up on it. Need a jack and some help to get it back on. The sensor to the right of the oil filter is the oil pressure switch that runs the hour meter on the dash. Sorry, that's all I know.

The best way to find an leak when every thing is all oil covered is to spray the area you think the leak is coming from is to spray it with foot power. I have found fuel leaks in sprint car tail tanks with foot power spray.
