From the PTO driveline through the main and reversing gearboxes, feedrolls, cutterhead, blower, and metal detector, this 150-page Sperry New Holland 782 service manual PDF (OEM ID 40078211) walks the whole harvester end to end. Factory wiring diagrams trace the limit switches, gearbox shift motor, neutral block, and spout control circuits, while the metal detector gets a troubleshooting section that takes up roughly a quarter of the book. Each gearbox procedure runs from removal through reassembly, with an optional equipment chapter covering the automatic hitch and hydraulic spout control. Check the smooth roll against its .030 inch (.76 mm) wear limit, and set main gearbox bearing preload at 12 to 18 inch-pounds on reassembly. Second cutting won't wait while the chopper sits. Bookmarked and text-searchable, the PDF lets you confirm what's worn before you call the dealer, so the parts you order show up right the first time.
