Changing Hydraulic Filters
Charge Filter
The charge filter removes particulate contaminants from the oil before the oil is directed into the traction and header drive
pumps. The oil maintains a positive pressure and is continuously supplied in these closed circuits during operation. The
charge filter has a high-pressure bypass of 345 kPa (50 psi) that allows oil to bypass the filter element during cold
temperatures and when the filter element is heavily loaded.
The charge filter must be replaced at regular intervals. The filter telltale is displayed on the Harvest Performance
Tracker (HPT). The charge filter must be changed after first 50 hours and every 500 hours thereafter. Follow the service
schedule on the HPT.
Refer to the following procedures to change the charge filter:
