1 Clean the valves, remove eventual oil carbon residue.
2 Check the possibility of utilization in the case of used valve, checking the recommended values.
Burnt valves or that present wear on the valve keeper grooves, damage on the stem chromium layer, deformations and wear beyond the permissible limit, are to be unconditionally replaced, exception made to the valve seat face and to the stem top (contact with the rocker arm) that can be reworked, provided they maintain the dimensions within the control values.
A Seat face angle
B Valve head diameter
C Valve length
E Valve stem diameter
F Width of the valve seat face
g Control diameter, relative to the position (H)
h Position relative to the control diameter (G)
