This document is page MA-32, "Service Data and Specifications (S.D.S.) — Engine Maintenance," from a Nissan factory service manual, uploaded to the gallery of a 1990 Nissan Micra. It provides inspection and adjustment specifications for the basic mechanical system: hot valve clearances (intake 0.25 mm / 0.010 in; exhaust 0.30 mm / 0.012 in), alternator drive belt deflection limits for used and new belts with a 98 N (10 kg, 22 lb) pushing force, radiator cap relief pressure (88 kPa / 0.9 kg/cm² / 13 psi), and cooling system leakage test pressure (157 kPa / 1.6 kg/cm² / 23 psi). Ignition and fuel system data for Canada includes spark plug types (standard BPR5ES, hot BPR4ES, cold BPR6ES), plug gap 0.8-0.9 mm, distributor air gap "close but not touching," ignition timing/idle speed for manual (2±2° ATDC / 750±50 rpm) and automatic (2±2° BTDC / 700±50 rpm in "D"), and idle CO of 2.0±1.0%. A tightening torque table lists values in N·m, kg-m, and ft-lb for the alternator bolts, valve rocker lock nut, oil pan drain plug, spark plugs, crank pulley bolt, and tensioner lock nut.
