54 Service Engine timing overview If it is necessary to disassemble the cylinder heads, the engine timing must be reset. These are the important markers when the piston of the first cylinder is at top dead centre. Put copper coloured chain link on arrow of bank II Adjust exhaust camshaft to advance Position the marker on the vibration damper on the housing joint: piston in 1st cylinder at top dead centre. S248_191 S248_192 Adjust inlet camshaft to retard Put copper coloured chain link on arrow of bank II Bank II Insert the mandrel for fixing the crankshaft into the threaded hole in the housing: piston in 1st cylinder at top dead centre. S248_190 S248_144
Place the copper coloured chain link on the marked tooth of the intermediate shaft and the bore hole in the housing S248_178 Place copper coloured chain link on arrow of bank I Bank I Normal tooth Marked tooth S248_194 Insert camshaft rule for aligning the camshafts. Inlet camshaft advance adjustment S248_193 Exhaust camshaft retard adjustment Place copper coloured chain link on arrow of bank II When placing on the lower timing chain copper, set the coloured chain link on the marked tooth and the marked tooth on the housing joint: piston in 1st cylinder at top dead centre. For a description of the exact procedure for setting the engine timing, please refer to the relevant Workshop Manual. 55
