Try taking the cover plates off either side of the clutch housing, you may have to remove the power steering pipe off the r/h one and replace it before starting the engine. Then shine a torch into the housing and see if you can find the leak. Unless its the input seal to the main pump which is only an o ring or a pump leak, the only other places it can leak from are the main shaft seals or the seal on the drive to the steering pump.
You will have to split the tractor to remedy the last two, but the main hyd pump can be removed through the l/h opening.
If your tractor has an assister ram there may be another small piston pump in the housing to the right, check this out as well.
On balance though, if it still leaks gear oil when parked, and I dont mean the bit that left in the clutch housing that will dribble a little for days, then I would checkout the main pump first because its the lowest place where oil can leak from when stopped and then only when the gearbox oil is full to the mark.

[QUOTE="dave_peters, post: 9222, member: 415"] Try taking the cover plates off either side of the clutch housing, you may have to remove the power steering pipe off the r/h one and replace it before starting the engine. Then shine a torch into the housing and see if you can find the leak. Unless its the input seal to the main pump which is only an o ring or a pump leak, the only other places it can leak from are the main shaft seals or the seal on the drive to the steering pump. You will have to split the tractor to remedy the last two, but the main hyd pump can be removed through the l/h opening. If your tractor has an assister ram there may be another small piston pump in the housing to the right, check this out as well. On balance though, if it still leaks gear oil when parked, and I dont mean the bit that left in the clutch housing that will dribble a little for days, then I would checkout the main pump first because its the lowest place where oil can leak from when stopped and then only when the gearbox oil is full to the mark.
