323000486 - 1036G CAMSHAFT (1) IN CAMSHAFT HOUSINGS (2)

CAMSHAFTS

Cast iron, with induction-hardened cams.The exhaust-side camshaft is controlled directly by the chain and transmits power to the inlet-side camshaft by means of a pair of straight toothed gears.The exhaust side camshaft also controls the high pressure pump, whilst the inlet side camshaft controls the vacuum unit.

TAPPETS

Each valve uses a hydraulic tappet operated by a rocker, in turn, moved by the camshaft.The rockers are designed to prevent serious damage to the other engine components if the timing belt slips or breaks; in effect, as a result of pre-set fracture lines, the stresses caused through the contact of the valves with the pistons are absorbed.
