V. OPERATING INFORMATION

Hydraulic System

The auxiliary hydraulic system is an open type directly mounted behind the heavy duty variable displacement pump. This system consists of dual gear pumps that supply the required hydraulics to operate the full time power steering unit, lift cylinders, and various cutter or pullers.

After supplying each of these systems, the hydraulic oil is sent to the oil cooler in front of the engine coolant radiator. Here it is cooled and then sent back to the hydraulic oil reservoir.

The front, larger gear pump (fig. 5.14, item 1) supplies only the cutters or pullers. The rear, smaller gear pump (fig. 5.14, item 2) supplies power steering and the lift cylinders.

DO NOT GO NEAR LEAKS. High pressu re oil easily punctures skin causing injury, gangrene, or death. If injured, seek emergency medical help. Immediate surgery is required to remove oil. Do not use finger or skin to check for leaks. Lower load or relieve hydraulic pressure before loosening fittings.
