Check that the camshaft gear works properly: if it is damaged or does not move smoothly,
replace the timing chain and the camshaft gear.

Check that they do not show blue colouring, cracks or scratches; otherwise, replace the
camshaft, gear and chain.
•
Fasten the camshaft in horizontal po-
sition, as shown in the figure, and make
it spin to check the eccentricity with a
dial gauge; if necessary, replace the
part.
