Nissan Micra Engine Overhaul - Cylinder Block, Crankshaft & Piston Diagram EM-20

This is page EM-20 of a factory service manual section titled "Engine Overhaul — Cylinder Block, Crankshaft and Piston." It presents an exploded parts diagram of the engine bottom end, identifying components including the cylinder block, crankshaft, main bearings and main bearing caps, pistons, piston rings, piston pins, connecting rods, front and rear crankshaft oil seals, rear oil seal retainer, water pump suction pipe, engine rear plate, flywheel (M/T model), drive plate (A/T model), oil pump assembly (body, inner/outer rotors, rotor shaft, regulator valve, spring, pin, cover), oil strainer, oil pan and associated gaskets. Torque specifications in N·m (kg-m) are given for key fasteners: main bearing cap bolts 46-52 N·m (tightened in two or three stages), connecting rod nuts 29-34 N·m, flywheel bolts 59-69 or 69-78 N·m, oil pan bolts 5-7 N·m, oil pump bolts 16-21 N·m, and several small fasteners 4-5 and 6-8 N·m. Symbols indicate where sealant must be applied (gaskets, oil seals). The page notes that main bearing thickness must be selected to suit, and shows vehicle front orientation. A reader can learn disassembly/assembly relationships and fastener torque values for engine block overhaul.
