Had a reply all typed in yesterday, computer shut down for updates and lost it before I could post. At any rate, It seeems very few know that a change was made on the shift lever on these tractors. IH came with a kit with a 0-ring in the little funnel shaped shield on shift lever. It was factory on latest tractors. The original has a slot in shield to breathe past shift lever and is a real easy way for rain or wash water to enter. You need to drill a vent hole in main cover that the shield will protect it but not seal it. The bolts on main cover sitting in the well they are will leak water also, a little silicone under head will cure that. Next, condensation can be huge, just look into the rear under the cover during cold damp weather and it is covered with frost , even on top of the oil itself. Any suction leaks will aerate the oil and even make good oil look yellow and foamy. The suction tube seal on pump intake is critical, it is a lip type seal pressed on the tube and must be spaced exactly the correct distance to seal properly. Pump also has an 0-ring where tube goes into pump. O-ring between two housings can leak also. I would never run without a filter, might revert back to the original screen style if absolubely necessary or find one of the course screened by pass valves on the paper filter. Adding the extended larger filter would no doubt help also. You can never get all the moisture out of good quality hyd fluid by letting it stand as it is formulated to retain some moisture in suspension. When it settles out it is saturated. Would have to be heated to evaporation temp to expel it from the oil. Also when draining, the section under the ta with t shaped cover does not drain, power steering bolster and fast hitch cyl or loader cyl don't drain. Clyinder can be flushed but not real easy. I used to save good looking oil from newer tractors like magnum, run it through filter on recieving barrel and use it to flush out these old tractors as they are really a problem.
