5.5.8 Changing Hydraulic Filters
Charge Filter
The charge fi lter 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
fi lter has a high pressure bypass of 345 kPa (50 psi) that allows oil to bypass the
fi lter element during cold temperatures and when the fi lter element is heavily loaded.
The charge fi lter must be replaced at regular intervals. The fi lter telltale is displayed on the Harvest Performance
Tracker (HPT). The charge fi lter must be changed after fi rst 50 hours and every 500 hours thereafter. Follow the
service schedule on the HPT.
Refer to the following procedures to change the charge fi lter:
• Removing Charge Filter, page 253 .
• Installing Charge Filter, page 253 .
