2. Checking cam lift and pin alignment
Place the camshaft (4) on the tailstock centres (1)
and, using a dial gauge (2) check that the lift of the
cams (3) corresponds to the values given in the fol-
lowing table:
intake cam
exhaust cam
pump injector operating
cam
3. Again with the camshaft (4) on the tailstock centres
(1) using a dial gauge (2) check the alignment of the
supporting pins (3) : it must be no greater than 0.020
mm (0.0008 in). If there is any greater misalignment,
replace the shaft.
4. To check the assembly clearance, measure the in-
side diameter of the bushings (Figs. 6 and 7) and the
diameter of the pins (Figs. 1 and 2) of the camshaft:
the difference will give the actual clearance.
If the clearance is greater than 0.160 mm (0.0063 in),
replace the bushings and, if necessary, the camshaft
as well.
