Part of the Case Operator Manuals.
Every one of the 370 pages in this Drott 2500 Cruz-Crane service manual pdf (OEM #S406152M3) focuses on getting your crane back to factory condition. Inside, you get full electrical control circuit wiring diagrams, heavy-duty troubleshooting charts, and complete hydraulic schematics covering the outrigger, steering, and winch circuits. Open the mechanical systems section to find step-by-step teardown procedures for the torque converter, turntable swing, and center swivel module. Verify the massive 200-gallon hydraulic system is topped off, then lock down the 3/8-inch axle pinion bearing cage capscrews to exactly 30-40 lb-ft. Your machine is down, and guessing at specs wastes valuable shop time. Download this digital file directly to your tablet, jump straight to the exact procedure using the built-in bookmarks, and get back to work.
