Nissan Micra Engine Torque Specs - Tightening Torque Chart (EM-34 S.D.S.)
Service Data and Specifications tightening-torque tables for engine outer parts (alternator, starter, manifolds) and internal parts (cylinder head 54-59 N·m, main bearing cap, connecting rod 29-34 N·m).
This page is from a factory service manual, section EM-34 (Engine Mechanical), titled 'Service Data and Specifications (S.D.S.) – Tightening Torque'. It provides two complete torque specification tables in N·m, kg-m, and ft-lb units. The first table, 'Engine outer parts', lists torque values for the alternator bracket and adjusting bar bolts, starter motor to transaxle, engine-to-converter/clutch housing bolts, clutch cover fixing bolts, fuel pump nuts, intake and exhaust manifold nuts, spark plugs (14-22 ft-lb), crank pulley bolt (61-69 ft-lb), water outlet, carburetor, gusset bolts, engine-to-transaxle bolts, and oil pressure switch. Engine mounting bracket torques are cross-referenced to page EM-19. The second table, 'Engine internal parts', covers the camshaft pulley bolt, connecting rod nuts (22-25 ft-lb), cylinder head bolts (47-51 ft-lb, with a note to tighten after referring to EM-16), flywheel and drive plate bolts, main bearing cap bolts (34-38 ft-lb, tightened or loosened in two or three stages), oil pan bolts and drain plug, oil pump and strainer bolts, rocker shaft/cover/arm fasteners, tensioner lock nut, water pump bolts, and rear oil seal retainer. This is a key reference for anyone rebuilding or servicing this carbureted transaxle-mounted engine.
