I have a 2004 Case 750K series II with 1600 hours. The dozer will operate perfectly for 5-6 hours and then the "low charge pressure" warning light will illuminate and the buzzer sounds. I'll shut it off and come back the next day for 5-6 more hours before it happens again. I changed the hydraulic fluid, hydraulic filter and trans filter with no change. Even when the light comes on everything seems to be working fine and all the temp gauges are in line. Any idea what the problem is?
You need to verify the charge pressure
Should I do this anytime or just when I encounter the problem?
