Nissan Micra Timing Belt Exploded Diagram & Torque Specs - EM-4 Service Manual
Exploded parts diagram of the timing belt assembly with pulleys, tensioner, dust covers and torque specifications.
This scanned service-manual page, titled "TIMING BELT," presents precautions and an exploded parts diagram for the timing belt system. Six bulleted precautions instruct the technician not to bend or twist the timing belt; not to rotate the crankshaft or camshaft separately after belt removal (or the valves will hit the pistons); to keep oil, water, and dust off the belt, pulleys, and tensioner; to ensure the No. 1 cylinder is at T.D.C. on its compression stroke before installing the belt; to position the belt in the correct direction; and to adjust belt tension with all spark plugs removed. The exploded illustration (figure SEM429E) identifies components: timing belt, upper dust cover and gasket, lock washer, camshaft pulley, tensioner and tensioner spring, crankshaft sprocket, crankshaft pulley, lower dust cover, water pump assembly, and cylinder block, with a vehicle-front orientation arrow. Torque specifications in N·m (kg-m, ft-lb) are given at several fastener locations: 9-12 (0.9-1.2, 6.5-8.7), 4-5 (0.4-0.5, 2.9-3.6) at two locations, 15-17 (1.5-1.7, 11-12), and 83-93 (8.5-9.5, 61-69) for the crankshaft pulley bolt. The page is numbered EM-4 (Engine Mechanical section).
