Part of the John Deere Repair Manuals.
This is the factory repair manual for John Deere 9300T, 9400T, 9320T, 9420T, 9520T and 9620T track tractors, covering the 12.5 L in-line six from the 268 kW (360 hp) 9300T up to the 373 kW (500 hp) 9620T. It is a teardown and rebuild book: component removal and installation, torque values, sealants, and step-by-step repair for the engine, Power Shift and Mechanical Shift transmissions, drive systems, rear axle with outboard planetary final drives, steering differential, hydraulics, cab, and the track frame with its tension cylinder and accumulator. It also includes the dealer fabricated tool drawings you need for pullers and fixtures. If a major component on one of these machines is coming apart, this is the book that walks you through it.
