Nissan issued this book to its own service network as document SMEPDS1E00-00, and this 240 page Nissan PD6, PD6T, LK850 II service manual PDF is that factory original, not a rewrite. A full Disassembly Judgment chapter helps you decide whether the engine truly needs an overhaul, running compression tests and trouble diagnosis before you commit to a teardown. generator, and regulator circuits, while the fuel system chapter carries the injection pump, boost compensator, and nozzles all the way to calibration figures. Set injection start pressure to 200 kg/cm² on a PD6, 230 on a PD6T, and hold crankshaft journal clearance between 0.04 and 0.13 mm before the caps go back on. Chasing pump timing without the factory data wastes a day. Bookmarked and text searchable, this PDF stays open beside the stand wherever your rebuild happens.
