Part of the Case Repair Manuals.
This 598-page Case 1816 Service Manual (OEM #8-41040) covers the full Uni-Loader lineup: 1816, 1816B, and 1816C. You get complete wiring diagrams for the electrical system, hydraulic schematics covering the equipment pump, control valves, and cylinders, plus a full troubleshooting section for hydrostatic drive on machines running Vickers or Sundstrand piston pumps. Inside you'll also find torque specs, lubrication intervals, and engine procedures for Tecumseh and Onan power plants. Check the hydraulic reservoir capacity at 15 quarts (14.2 litres) with filter change, and confirm piston pin diameter runs .687 to .688 inch before you reassemble anything. No more guessing whether that wiring fault is a bad ground or a blown fuse. Bookmarked by section so you can jump straight from engine teardown to loader linkage, open it on your phone in the shop and chase the fault to its source.
