Thesurfaceofthecamshaftpinsandofcamsmustbe
extremely smooth. In case any trace of meshing or scratches
are detected, replace the shaft and the relevant bushes.

Using a micrometer (1), check the diameter of the camshaft
(2) supporting pins on th e two perpendicular axles.
Checking cam lift and pin alignment
Place the camshaft on footstocks and, throughout a
centesimal comparator placed on the central support, check
that the radial oscillation does not exceed 0.015 mm
otherwise replace the shaft.

The front camshaft bush (2) must be thrust in the respective
seat.
There must be no trace of meshing or wear in the inner
surface.
Using a bore meter (3) measure the front adiameter of the
camshaft bush (2).
Measurements must be made on two perpendicular axles.
