All 580 pages of this Case 3388, 3588, 3788, 6388, 6588, 6788 service manual pdf (OEM #GSS-1490-2) focus on keeping your Case tractors pulling hard in the field. Inside, you get full electrical wiring diagrams, complete power priority hydraulic schematics, and extensive troubleshooting charts for the Power Flow gear drive. We packed this reference with step-by-step teardown procedures for the independent power take-off (IPTO), torque amplifier overhauls, and multiple control valve diagnostics. Verify your orifice screen opening is exactly .508 mm and tighten the torque amplifier solenoid to 10.8-13.6 N-m before running pump standby pressure tests. You cannot afford to guess on hydraulic flow rates during a breakdown. Grab this bookmarked digital download, pull it up on your shop tablet, and fix the machine right the first time.
