- If no faults are found during the above checks,
you can use the same valves. To obtain better
sealing performance, grind the valve seats. Grind
the valves gently with a fine-grained lapping com-
pound. During the grinding, keep the cylinder head
with the valve axes in a horizontal position. This
will prevent the lapping compound residues from
penetrating between the valve stem and the guide
(see figure).
CAUTION
TO AVOID SCORING THE FAYING SURFACE, DO NOT KEEP ROTATING THE VALVE WHEN NO
LAPPING COMPOUND IS LEFT. CAREFULLY WASH THE CYLINDER HEAD AND THE VALVES
WITH A SUITABLE PRODUCT FOR THE TYPE OF LAPPING COMPOUND BEING USED.
CAUTION
DO NOT REVERSE THE FITTING POSITIONS OF THE VALVES (RIGHT - LEFT).
Inspecting the springs and half-cones
- Check that the upper spring caps and the cotter
halves show no signs of abnormal wear.
- Measure the unloaded spring length.
