Part of the Case Repair Manuals.
Need factory-level overhaul procedures for your Case or International 3104, 3105, or 3106 rotary mower? This 37-page service manual (OEM #GSS-1494) covers angle drive teardown, cutter bar rebuilds, hydraulic cylinder service, PTO drive train knuckle work, and knife and disc replacement from start to finish. Inside: a full standard torque table with bolt type identification, hydraulic schematics for the lift cylinder circuit, and exploded views of every major assembly. You get complete overhaul sequences for the angle drive, drive pulley assembly, and disc bearing service, each broken into removal, disassembly, and reinstallation steps. Press the disc hub onto the gear shaft with enough shims to set end play at 1-4 mm (.004-.016 inches); bench-test the hydraulic cylinder at 200 kPa (29 psi) and hold pressure to confirm zero seal leak. Every hour the mower sits costs you money. Bookmarked by section; open on any device, search a spec, and get back to work.
