9.3a Turn the engine until the O mark (A) aligns with the static marks (B)...

 

'O' marks on the inlet and exhaust camshaft sprockets are aligned with the cylinder head surface with each mark on the outside of its respective sprocket (see illustrations).If the 'O' marks are on the inside of their respective sprockets, turn the engine one full turn (360°) until the 'O' mark on the alternator rotor again aligns with the notches in the inspection hole. The camshaft marks will now be correctly aligned.

4 Remove the camchain tensioner (see Section 8).

Gears (arrowed) align with the cylinder

5Mark the front edge of the upper camchain guide to aid reassembly. The four camshaft holders are marked A, B, C and D, with corresponding marks on the inside of the cylinder head (see illustration).These markings ensure that the holders can be matched up to their original locations on installation. If no markings are visible, make your own using a felt pen. Before disturbing the camshaft holders, make a sketch of the layout as a further aid for installation.

6 Unscrew the camshaft holder bolts for the


camshaft being worked on, evenly and a little at a time in a criss-cross pattern, until they are all loose (see illustration).While slackening the bolts make sure that each holder is lifting squarely away from the cylinder head and is not sticking on its locating dowels. Caution: If the bolts are carelessly loosened and the holder does not come squarely away from the head, the holder is likely to break. If this happens the complete cylinder head assembly must be renewed as the holders are matched to the cylinder head and cannot be renewed separately. Also, a camshaft could be damaged if the holder bolts are not slackened evenly and the pressure from a depressed valve causes the shaft to bend. Remove the bolts, noting their positions, and the upper camchain guide, then lift off the camshaft holders. Retrieve the dowels from either the holder or the cylinder head if they are loose (see illustration).Disengage each camshaft sprocket from the camchain and lift each camshaft out of the head. The camshafts are marked for identification. The inlet camshaft is marked 'IN' and the exhaust camshaft is marked 'EX' (see illustration).
