It is unlikely that the valve clearance adjusting shims will be displaced from their recesses in the cam followers because of the suction of the lubricating oil, but watch that this does not happen; the shims must also be retained in their originally fitted sequence. 12 Remove the previously loosened camshaft sprocket bolt and take the sprocket from the camshaft. 13 Unbolt and remove the camshaft end cover with its gasket. Withdraw the camshaft (photos). 14 Refitting is a reversal of the removal process, but observe the following points.

8 On completion, refit the camshaft cover and gasket. fitted if it is to be completely removed. The lettering on the belt is normally legible from the crankshaft pulley end of the engine when the belt is as originally fitted. 11 Unbolt the camshaft carrier and lift it sufficiently from the cylinder head to break the seal of the mating faces. Note: It is important not to allow the cam followers to pull out; they must be retained in their original locations. This can be done if the carrier is raised very slowly, until the fingers can be inserted to prise the cam followers onto their respective valve spring retainers.
