Though I'm not sure it is all applicable, hear is a repeat of the advice I gave in a prior post:

When the tractor is cold, I would remove old screen and drain as much fluid as possible from the res. If you can, use a suction gun (looks like a grease gun that sucks) to get all of the fluid you can out of the system. I would then replace the screen and fill the res with new fluid. I would use an open hose on a remote cylinder connection into a bucket. Before starting the tractor, move the control lever to the position that will apply pressure to that hose. Then, with the lever moved, momentarily start the tractor 10 to 15 seconds. This should flush out that line into the bucket. If milky fluid is still comming out fill the res with new fluid again, and repeat until new fluid comes out. Then connectr to the other remote line and do the same thing, till clean fluid comes out. Refilling of course to prevent air from entering the pump. Next (if i was thorough) I would remove one of the FH cylinder hoses and blead that till new fluid came out. then the other side of the FH cylinder. This process prevents old fluid from being sucked back into the res. and also prevents the mixing (as much as possible) old and new fluid. Working the tractor for several hours will eventually drive off the remaining moisture from the system. Good luck, JimN
