With out being there to do some checking myself i am going to throw a couple things at ya to check. as for it being air locked Nah as they are self bleeding. If ya have full T/A function and ya have brakes i am thinking here since you found dirt or what ever it was in the steering orifice and ya have pressure that your flow divider is sticking or that you may have a blowen O/ring or gskt in the MCV. So here ya are going to need a I T manual and set down and read all about the MCV then and only then remove it from the tractor and start taking it apart then with a caliper measure the free length of each spring and check to make sure that all valves float free in there bores . Everything must be kept CLEAN and use NO RAGS to whip off anything . Clean in clean parts washing fluid or diesel and blow dry . Check for any burrs on the valves and lightly polish with vary fine emery . If you are in doubt about the MCV pump change it NOW and do not second guess here as you do not have the means to flow rate it . IF you do not thing you can handle this job then take it to someone that really knows how not someone that THINKS he knows how.

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul ...
