Good day everyone! I have a Case 5150 manufactured in 1996 and I am pleased with him except 2 facts: for a whatever reason when I fully steer left or right the power is cut off and I have to press down one or two times the clutch in order to move further (tractor's engine is running during whole process ) and this is became annoying, I have talked with a mechanic and he said that it might be a faulty sensor which is located near the clutch pedal but I want to check other opinion's before I start acting. The second fact is regarding the hydraulic system, seems like manual lifting does not work, I set the automated lever in the right position to use the manual lifting but still nothing. I investigated a little bit this issue and saw that there is fluid running in the system, however noticed a solenoid which is located near hydraulic distribuitor but to reach it I have to take down the seat. If anyone encountered one of this issue I will be thankful if I could get any information to solve this issues, thank you.

The drive problem is most likely related to hydraulic flow... you need to do a flow test

Did you do a flow test?

Know someone that had this problem they spoke to everybody and his dog about the problem started with the most expensive bits first cost a fortune and still isnt right, its been said in the past that a hydraulic problem with these tractors can be a nightmare and trying to isolate the problem is the only way to cure it ,has the search shown up other threads to go on(I think someone said !!!!!!the trailer brake system can cause funny problems) Good luck not what you are looking for but it may be a simple fix

Have read through this as far as your drive fault goes.
Usually if the power shift drops out when you press the brakes or pull the steering to full lock it's a compensator fault.
First thing to check is the low pressure standby, it wants to be 600/700psi.
View attachment 860486-31e0b106e3ed96854c443ac5e34bca8b.pdfHydraulic fault ? First check has to be fender buttons & the earth wire under the LHS wing at the back.

Does it happen when you are shifting forward and reverse. Sometimes there is a solenoid that sticks, back right hand side.
Will try to run all steps provided by you and will reach you out with a feedback
I will ask my father as he is the one using the tractor
Hello everyone, I am coming with an update: so both problems described above are persisting but we changed the hydraulic pump as it had a strange noise when the oil temperature raised up but the low pressure standby is still the same like before changing the pump (around 150 bars ). Does anybody know what else should I do? Thanks for help.
Yes, it does happen but only if the steering wheel is either to max left or right.
Could you please indicate more specifically where is that compensator valve located?

It's bolted onto the back of the pump, it's the back section.
You have the piston pump, then the 3 point linkage hitch valve & then the compensator unit.
Follow through precisely what's on the attachment I sent.
I know a few years ago, but does anyone know the outcome of this ? Got the same problem, drive disengaging when any hydraulic function is activated. Steering/spool and right hand brake pedal only. Not left. Can overcome it by giving it plenty of revs and then it seems to behave
Any advice appreciated
Thanks in advance
