Part of the John Deere Repair Manuals.
All 456 pages of this John Deere 6076 Technical Manual (OEM #CTM42) focus on one engine: the 6076 diesel, as fitted to John Deere CTS Rice Combines. Inside you get a full engine rebuild sequence with disassembly and assembly order, detailed procedures for cylinder head and valves, cylinder block, crankshaft, camshaft and timing gear train, plus complete coverage of the lubrication, cooling, air intake, exhaust, and fuel systems. System diagrams and a full troubleshooting section walk you through diagnosing malfunctions before you pull a single bolt. Head bolt torque runs a four-step sequence: snug cap screw No. 17 to 100 N·m, work through the remaining screws to 100 N·m, retighten the sequence to 125 N·m, then turn each an additional 90–100 degrees. Your machine is down. Get the factory answer on the first try. Bookmarked and searchable; jump to any system or pull up a spec by keyword on any device.
