MAIN DATA ABOUT CAMSHAFT PINS
Camshaft pin and cam surfaces shall be absolutely smooth; if they show any traces of seizing or scoring replace the camshaft
and the bushes.
* Data concerning the distribution shaft assembled on the engines with serial numbers starting from 01/01/2005
- Check the alignment of the supporting pins, setting the
camshaft as illustrated.
By means of a magnetic based comparator (1) read the
alignment error that must not exceed the one indicated on
the figure; otherwise replace the distribution shaft.
Check the useful cam lift that must be the same for both
the inlet and exhaust; if it is not, change the camshaft.
- Using a feeler gauge (1), check that the clearance between
the plate (3) retaining the camshaft (2) to the cylinder
assembly and the driving gear (4) is from 0.070 to 0.175
mm.
Check that the teeth of the driving gear (4) are neither
broken nor excessively worn.
The driving gear (4) of the camshaft is removed with an
extractor.
For assembly, heat the gear (4) to reach a temperature
difference of 250°C between it and the camshaft.
