These are a lot of questions. I try to answer them.
1 For oil I use THG hydr transmission fluid, allready for 20 odd years in the one tractor'in the other one sinds i bought it 8 years ago.2 It has been a while and can't remember the pressure values but have set them according to the manual.pto valve preasure i never checked 3 The oil and filters have been changed when i started to have these problems, cause the filter came to mind as the first thing to give trouble.
the case drain is wide open on both tractors. 4 the tractors are both early 70's. 5 one tractor has just 2 remotes,that is the one that kicks the pto out when I brake, about once or twice an hour while baling. and has the powersteering cut out once in a while to, but not both at the same time. the other tractor has 4 remotes,I added 2 to the side of the original valves. I have a front end loader on it.
This one does most of the squeeling,and stops all hydr functions when it does.
The problem is that these troubles happen once in a while, some times it works fine for weeks and all of a sudden it can happen 10 times in a row. I don;t have all that fancy equipment such as flow rators ,charge pumps and such.
I tought I could figure it out with a oil gauge in the right port. I guess i am wrong.
