[quote=&quot;admin&quot;:2jmtm96g]Those bolt holes where the oil is coming out near the brake pedals go all the way through. That middle section is supposed to be dry, so a seal is leaking in there, most likely in the PTO clutch area.

I agree with John, the first thing I would do is see about raising the hydraulic oil level. Those pumps can whine, especially when they get worn. A worn pump will also make a lot of heat. Still, it could be an internal leak somewhere else that is letting oil out, and causing the pump to work constantly and building the heat. I'd try raising the level before tearing everything apart. I also wouldn't go any thicker than the hy-tran oil.

The brake is probably soaked with oil. It isn't too tough to fix, but you'll need to replace the seal on the bull pinion shaft that the brake discs ride on, or it is just going to leak again. Pulling the seal is easy enough, just get a drill, drill a couple of holes into the seal, then screw a sheet metal screw into the holes, and then grab the screws with a pair of vise grips and pry the seal out. Carefully drive the new one in and the leak should be fixed. Take the brake discs and clean them real good with carb cleaner or brake cleaner. You need to get them dried out for them to work correctly.

I see that the pipe and elbow look new coming out of the right front corner of the hydraulic unit. Is that just for pumping the hydraulics down, or was something else done in this area?[/quote:2jmtm96g]

Thanks Chris
    As for the elbow &amp; tube with cap, I put these where the drain ( pipe ) plug goes in, to aid in pumping out the old hyd fluid, whatever it was, and not make a mess in the process. I used the hose from a Sure Drain, which fits perfectly on that brass pipe nipple, and directs the fluid right into the oil pan or jug on the footrest. I decided to leave them there for now, as they don't get in the way, in case I needed to flush the system further. -I didn't know what was in there, and thought that the Hygard might not be compatible with the small amount of whatever's still in there. I still wonder if maybe I shouldn't flush it again. 

    It occurs to me now, that it's possible that the whole hyd situation could be the result of a break-down of the fluid, due to incompatibility? I wonder if I should have gone ahead and flushed it out again, and should probably have changed the filter too. It seems that you can still order that filter from Agco, so I am going to order one tomorrow. I am told that the breather elements are NOT available anymore-hope that isn't true. I didn't like the whole idea of pumping it dry in the first place, but I got ahold of an operator's manual, and that's how it says to do it. I did stop right away when it wasn't a stream anymore, and starting to sputter.  The Super 55 manual.... I decided to go back and look at it, and it does say to use 10 weight oil for below 32 F, and 30 wt. above, or 10w30 for year round. I suppose it has little or no  resistance to foaming, though. As for the heat, I put in one of my posts that after it cooled down and I went back out and used it again for 45 minutes to an hour on much flatter ground, it never got hot like before, where I couldn't hold the dipstick for long. It got pretty warm, like it always does when in use for awhile and is up to operating temp., but not like in the prior incident. Hopefully the stand-pipe will still be available after all of these years. Do you know if the shaft seal is still available for the bull pinion shaft? 

    I was worried when I saw fluid coming from those holes... I am no expert on these tractors, but I couldn't see where anything would be leaking, that far fwd in the case. When I first saw oil coming from the holes, I was pretty confused. It was sort of milky, like there was some water in it. I found water in the trans fluid, so that makes it a possible culprit. Once I changed the fluids, it puked out a little bit more of the milky stuff, then pretty much stopped. Now, I get much smaller amounts, but it's blackish in color, and spurts out small droplets across the footrest, with only a small amount of oozing down the side of the case. Is it possible that the PTO clutch is slinging it, and it's getting out the holes that way? 

    This is a great old tractor, I hate to see stuff like this happening. I was hoping to clean it up and paint it up, but maybe I'd better wait on that. It all came on so fast, with the leaks that it didn't have before, and the hydraulic whine came on very fast. It would be nice if there was a cooler available for the hydraulic system. I will try to get ahold of a standpipe kit like John mentioned before I use it any further. Reading the Oliver operator's manual,  I also noticed that the kit will give two more quarts capacity, which should help with cooling, too. 

Thanks again!
