Part of the New Holland Repair Manuals.
Every one of the 882 pages in this New Holland Tractor Repair Manual targets the 4835, 5635, 6635, and 7635 models, covering everything from engine teardown to PTO clutch service. You get full electrical circuit diagrams for the starting and charging systems, hydraulic schematics for the rear mechanical lift and remote auxiliary control valves, and a dedicated troubleshooting section for engine faults before you start pulling parts. Check your PTO clutch release spring under a 67.6 kg load, and confirm the alternator tops out at 45A before you chase a phantom charging complaint. Stop swapping components on a hunch. This PDF opens on laptop, tablet, or phone, with bookmarks built in so you can jump straight from the cover to the wiring or hydraulic sections and get back under the hood.
