have a cat 428f with plastic hydraulic tank which is pushing out oil from the tank cap which is plastic.. hydraulic pump has been checked and even on start up the oil comes out the cap.. is the tank supposed to be pressurised.. could it be a matter of replacing the cap.. rather lost on this one
Can you supply a Serial Number..? Too many options of 428F out there to be guessing on what tank arrangement you might have .........
G'day Brett How did you go fixing this issue? Regards.
