SPRINGS PACK CHECK
When the valve seats on the heads are trued, after having fitted the valves on the heads, it is necessary
to check that the above said springs are compressed between 35.700 mm - 36.000 mm (1.405 - 1.417
in). To reach this value, fit washers (code 14 03 73 00) with a 0.3 mm (0.012 in) thickness. After reaching
the maximum opening, the springs shall still have a length of mm 1 - 1.75 mm (0.039 - 0.069 in) before
the inner spring is packed.
Checking the valve guides
Use a punch to extract the valve guides from the
heads.
The valve guides should be replaced only if the
clearance between them and the stem cannot be
eliminated by simply replacing the valves.
To refit the valve guides on the head, follow this
procedure:
•
Heat the head in an oven at approxi-
mately 60°C (140°F).
