Part of the John Deere Repair Manuals.
This is the John Deere TM400819 Technical Manual for 6230, 6330, 6430, 7130 and 7230 tractors, a 1200-page PDF written for the repair and overhaul of these Mannheim-built premium models. It is the factory service reference, covering removal, installation, testing and adjustment across every major system on the machine.
Inside you get full coverage of the POWERTECH diesel engine, the SyncroPlus, PowrReverser and PowrQuad transmissions, drive systems and final drives, hydrostatic steering and brakes, the hydraulic system with SCVs and hitch, plus the electrical system and electronic control units. Specifications, torque values and tune-up data are grouped up front for quick reference.
Owners, independent mechanics and restorers can use it to diagnose a fault, follow the correct disassembly sequence, and reassemble to Deere torque specs. Download it as a PDF and print any section you need at the bench.
