Good Day Everyone,
I have a international 1066 that seems as if the hydraulics are sucking air from somewhere. It seems as if its effecting both the main system and the MVC system. When you start the tractor everything works fine until you get it up too operation revs, 1500 or greater, than the steering, clutch and TA seems to stop working. It will even stop moving. Adding to this, if I try to raise the haybine, its very jerky and slow. When I undo the connections I do see the fluid is a little foamy.
Here what I have done, I have changed the MVC pump previously as it was bad. It has chevron 1000 THF in it, 24-25 gallons. I have pulled the filter and it new now.
My question is,
Do the pumps have enough suction to pull air from the outside into the reservoir causing the pumps to suck air and foam the fluid? Is there any where else other than the filter housing where both systems are connected?
