Outlet:
- Check that there are no signs of wear on the faying surface with the set screw articulated terminal.
- If no faults are found during the above checks,
the same valves can be reused. For better sealing
results, we recommend grinding the valve seats.
Grind the valves gently with fine-grained lapping
compound. Upon grinding, keep the cylinder head
in horizontal position. This will prevent the lapping
compound residues from penetrating between the
valve stem and the guide (see figure).
