Remove the camchain tensioner by unscrewing the
two retaining bolts.
Remove the camshaft and its bearings from the
head, taking care not to let the camchain fall into
the timing case. For camshaft inspection and dis-
mantling, refer to what is said in the chapter on as-
sembly.
Remove the water pump shaft, taking care that the
gear does not fall into the crankcase. Remove the
fixed camchain guide.
Unscrew the cylinder head retaining nuts, which are
screwed onto the studs, and the bolt on the water
pump side. Then remove the head and the head
gasket, taking care also to remove the dowels.
If the water pump shaft bearings are to be replaced,
extract the one on the outer side by pressing it with
a padded drift towards the inside of the timing case
until it comes completely free.
For the inner bearing, use a slide hammer with a
suitable internal extractor.
