Part of the Case Repair Manuals.
Case issued this 886 page book as publication 8-66102, the factory Case 1818 service manual PDF covering the 1818 Uni-Loader in both its Onan P218 gasoline and Kubota D850 diesel builds. Foldout electrical and hydraulic schematics ride in the rear pocket, one wiring layout per engine, tracing circuits from the key switch through the starter, charging system, and gauges. Hydrostatic troubleshooting works the drive from piston pump through motor, sprockets, chains, and axles, while the hydraulics section rebuilds the loader control valve, auxiliary valve, and cylinders. Set rocker shaft bush clearance between 0.0005 and 0.0026 inch, and pull grade 5 half inch hardware to 80 to 96 pound feet. A dead hydrostat stops the whole job. Bookmarked and searchable by keyword, this PDF puts the correct procedure in front of you and gets your 1818 running again.
