Part of the Case IH Repair Manuals.
All 425 pages of this Case IH 3152 and 3162 Draper Header Service Manual (OEM #47730908) are factory-written to get your flex or rigid header cutting clean again. Inside you get hydraulic schematics tracing the double gear pump, main control valve, and both reel positioning circuits, plus wiring diagrams covering header leveling control, reel speed and position, and the feeding control system. A full troubleshooting section walks you through the electrical harnesses and connectors before you pull a single wire. Set your auger drive chain tension to 7–13 mm total movement, then verify the Left Height/Tilt potentiometer reads 800–1200 Ω between pins A and C before chasing a leveling fault. Your header is sitting idle while you dig through forums. Download this PDF, pull it up on your tablet at the machine, and jump to any section instantly with built-in bookmarks.
