Need factory data for your W50, W60, or W70 wheel loader? This 594-page Fiat Kobelco W50, W60, W70 Technical Manual PDF (OEM #604.06.995.02) covers all three loaders in one book, front to back. Inside: full wiring diagrams with fault-finding charts, hydraulic circuit schematics for the hydrostatic travel drive, and step-by-step rebuild procedures for the A4VG pump and A6VM motor. You also get a dedicated service data section for each model, plus axle dismantling, Gleason backlash adjustment, steering, brakes, and frame work down to the main pivot. Set the working hydraulic primary relief at 210 bar, then torque the wheel nuts to 500 Nm before the machine rolls. A loader sitting dead over one missing spec is money burned. Bookmarked and keyword-searchable; pull it up on your phone, find the number, get back to work.
