While I do not know about your specific valve setup, I can share what I did with my 202.

First thing is to determine who made the loader to guide you to the valve manufacture if it is not casted into the valve. With that information try to search for a parts schematic for the valve. You will be looking for seals and or o-rings. If there are part numbers and if those parts are available you will be 1/2 way there. In my case I was able to track down seals, but I had hard part issues and I had to replace the unit with a current setup as it was not available.

If you can't find the information to guide you to the correct parts, if it was me I would wait for a time when I didn't need the tractor and take the valve apart looking for wear items that I could then try to match up. But as a backup, I would have in mind the new valve I would get and how I would install it if a repair was not possible.

With all the oil coming down from the top, how can you be sure it's coming from that small drain hole down there? Either way, at the very least your top and bottom o-rings on that spool and
maybe another are letting oil by them. Pretty sure that bottom hole is a drain, should something get by the o-ring.

I agree the top sides are also leaking and no doubt the whole thing needs a rebuild.
I know the oil is coming out that bottom hole because when I pull or push the tilt control I can see the oil leaking out that small hole at the bottom.Ive only had this tractor a few weeks so its been leaking for many years and the previous owner did almost no maintenance by the looks of it.I suspected it was the o rings failing. Thanks,Harold
