Part of the Case Repair Manuals.
This 110-page J. I. Case Shop Manual (models 730, 830, 930, 1030) puts the entire tractor line's engine, transmission, and Case-O-Matic overhaul procedures in your hands. You get complete wiring diagrams for the electrical circuit and distributor timing, hydraulic schematics covering the rockshaft, control valves, and pump, and a full torque section that doesn't leave you guessing on cap screws. Inside you'll also find LP-Gas carburetor adjustment, diesel injection pump timing, and steering gear overhaul laid out step by step. Set the power steering pump cover cap screws to 35 ft.-lbs. and hold roller clearance under 0.0015 inch; on Series 930 and 1030, seat that oil seal with its inner edge flush to the bore. No more guessing which shim pack or bearing liner your particular series takes. Bookmarked by section, so you can jump straight from the front axle to the final drives without scrolling through 110 pages on your phone in the shop.
