Rear PTO stalling under load, or a remote valve that will not hold? Answers live in the 884-page Case IH Farmall 45A, Farmall 55A Service Manual PDF, factory document 84300849, written for both tractors. Wiring diagrams trace lighting and starting circuits from key switch to glow plug, and hydraulic schematics lay out the open center mechanical remote valve so you can follow flow before you crack a fitting. Troubleshooting charts sit right beside the hydraulic and electrical section, and torque tables open the book. Test pump efficiency against 15858 kPa (2300 psi), set alternator belt deflection at 10 to 15 mm (0.39 to 0.59 in), and change the hydraulic filter at 50 hours, then every 300. A rebuild stalls at the one clearance nobody wrote down. Bookmarked and keyword-searchable, it downloads once and stays yours for every season you run this tractor.
