JD 425 Garden Tractor steering hydraulic leak

I have a bad leak of hydraulic oil from what appears to be maybe a cracked or blown O-ring on one of the tubes going into the steering pump on my JD 425 Garden Tractor. Does anyone have a copy of an exploded view of that steering pump? I'm confused as to how to get the line off to check what I believe to be O-rings between the line and the steering pump body. Any help in explaining how to remove those lines from the steering pump would be very much appreciated. Thanks. I am assuming its O-ring(s) but not sure at this point. It appear that two of the lines can be taken apart, and then it looks like there are two other lines that do not come off the steering pump? It appears the leak is from one of the lines that I believe can be removed but not sure if steering pump has to be removed or what. First time attempting anything like this. Again, appreciate any help.

# 14 0-ring is #T36492

The repair is not hard to do from a technical stand point but it is real PAIN to do. In Tim's parts view you can see the plate #2. This is held to the steering motor with bolts. All the lines have a shoulder made on them. This plate goes around the lines and then holds it against the orings and steering motor.

Remove the deck and the belly screens. You will need to lift the mower up to have room to work from the bottom. Remove the bolts that hold the plate tight. you can then wiggle/pull the lines down out of the steering motor. ALL four lines come out at the same time and all four need to go back in together. The orings slide on the lines, so they will stay in place. It just is fun getting all the lines started in the motor housing while getting the clamp plate in place. THEN getting the bolts started in the plate.

Check the lines for cracks. This is a common issue with the lines. So you can replace the orings and still have a leak.

Some tips:
1) I use an engine hoist hooked to the front bumper of the mower to really lift it pretty high in the front. 3 foot at the least. This way you can sit under it while your fighting to get everything lines up when you reinstall the lines/orings.
2) Take a picture of the lines before you take the clamp off. It is real easy to get the lines switched around under there. The two going to the steering cylinder can easily be switched.
3) When your done with the lines/orings clean the bottom of the frame/lines/entire area up with a degreasing cleaner. This area will collect dust/grass clipping terribly it there is any oil film left. After everything is clean and dry install the screen/covers.

Thank you kindly gentlemen!
