This is the Component Technical Manual (CTM3274) for John Deere's 3029, 4039, 4045, 6059 and 6068 diesel engines as built at the company's Saran factory in France - the European-market version of this engine family, valid up to serial number -499999CD. It's an engine-only manual, meant to be used alongside whichever machine's own technical manual tells you when to pull the engine for this level of work.
The manual opens with engine identification (how to read the serial plate) and general information, then an engine rebuild guide that walks the complete disassembly and reassembly sequence step by step, cross- referencing the detailed repair groups as it goes: cylinder head and valves, cylinder block/liners/pistons and rods, crankshaft/main bearings and flywheel, camshaft and timing gear train, lubrication system, cooling system, air intake and exhaust, and the fuel system. Each repair group opens with its own special-tools list, wear tolerances and torque values before getting into the procedure itself.
Beyond the repair groups, the back of the manual shifts to diagnosis and testing - engine system operation with a full sectional view, plus diagnostic test procedures for the air intake and fuel systems specifically. That combination of hands-on rebuild instructions and dedicated diagnostic testing is what makes this a useful reference whether you're doing a full in-frame overhaul or just chasing a specific running problem on one of these five engines.
