Make sure that the bearing sleeve on the inlet camshaft is positioned correctly.
5. The bearing sleeve of the inlet camshaft must be positioned so that the centrally bored blind hole points vertically upwards -Arrow- (the rib of the
cylinder head should also be at the center in relation to the bearing sleeve). In this position, the dowel pin in the bearing bore of the cylinder head
will fit precisely into the opposite off-center blind hole bore. Any other bores are through-holes for guiding the oil.
Position of bearing sleeve for inlet camshaft
6. Insert exhaust camshaft 4-6. Lay the timing chain on the flange for the sprocket, then insert the camshaft at overlapping TDC of cylinder 4 (the
outlet cams of cylinder 4 point towards the cams of the inlet camshaft -Arrows-).
Exhaust camshaft 4-6
7. Insert exhaust camshaft sprocket in the timing chain and position on camshaft flange. The four threaded bores in the camshaft flange must be
covered by the slots of the sprocket in the clockwise running direction of the engine approximately half way -Arrows-.
Position of sprocket 4-6 at 60° before TDC
8. Oil the bearing surfaces of the camshafts with new engine oil.
