EM-4 < PRECAUTION > PRECAUTIONS Precaution for Assembly and Installation INFOID:0000000009465995 • Use torque wrench to tighten bolts or nuts to specification. • When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified, do exactly as specified. • Replace with new gasket, packing, oil seal or O-ring. • Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction and blockage. • Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well. • Release air within route after draining coolant. • Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped). Then make sure that there are no leaks at fuel line connections. • After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage. Parts Requiring Angular Tightening INFOID:0000000009465996 • Use an angle wrench for the final tightening of the following engine parts: - Cylinder head bolts - Main bearing cap bolts - Connecting rod cap nuts - Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular tightening) • Do not use a torque value for final tightening. • The torque value for these parts are for a preliminary step. • Ensure thread and seat surfaces are clean and coated with engine oil. Precaution for Liquid Gasket INFOID:0000000009465997 REMOVAL OF LIQUID GASKET • After removing the bolts and nuts, separate the mating surface and remove the liquid gasket using Tool (A). CAUTION: Be careful not to damage the mating surfaces. • In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a plastic hammer to slide (2) the cutter by tapping on the side. CAUTION: Do not damage the mating surfaces. LIQUID GASKET APPLICATION PROCEDURE 1. Remove the old liquid gasket adhering to the gasket application surface and the mating surface using suitable tool. • Remove the liquid gasket completely from the groove of the liquid gasket application surface, bolts, and bolt holes. 2. Thoroughly clean the mating surfaces and remove adhering moisture, grease and foreign material. Tool Number: KV10111100 (J-37228) AWBIA1249GB PBIC0003E |
