17-5. MAIN HYDRAULIC SYSTEM ADJUSTMENT.
Main Hydraulic System Hydraulic Pump Control Adjustment.
The main hydraulic system operates at oil pressures up to 3,675 psi (25,339 kPa). Never
disconnect any hydraulic line or fitting without first dropping pressure to zero. Failure to
comply may result in serious injury or death to personnel.
Position drain pan under hoses.
Access to hoses is through cab engine access panel.
Disconnect hose 2935 (1) and remove preformed packing (2) from elbow (3) on high pressure filter (4).
Discard preformed packing.
Apply hydraulic oil to preformed packing (2).
Position preformed packing (2) on elbow (3).
Install flowmeter, adapters, No. 16 test hoses and test fitting in line between hose 2935 (1) and elbow (3)
on high pressure filter (4).
