Part of the Case Repair Manuals.
All 226 pages of this Case 1526, 1530, 1537 service manual PDF (OEM #9-71536) cover the complete 1500 Series UNI-LOADER, from engine and fuel systems through hydraulics, power train, brakes, electrical, and mounted loader equipment. Inside, you get hydraulic schematics for the 3-spool valve, lift control valve, variable speed control, and pump circuits, plus wiring diagrams tracing the starting circuit, alternator charging system, and ignition. Every trace is laid out so you can pin a fault without chasing ghosts. Power train covers drive belt, jackshaft, chain, clutch (Formsprag and Stearns), variable sheave, and gear box; brakes and electrical round out the full mechanical picture. Torque your clutch shaft nut to 35-40 ft-lbs, set wheel bolts to 85-100 ft. lbs., and fill the hydraulic system to its 19-gallon capacity. Every hour down costs money. Bookmarked and keyword-searchable, open it on your phone or tablet and start wrenching.
