If the red lead deposited on the valve indicates a poor contact
pattern, take either of the following corrective actions.
Lapping
•
Lap the valve in the following sequence.
•
Apply a thin coat of lapping compound to the seat contact sur-
face of the valve. Adding a small amount of engine oil to the lap-
ping compound can facilitate even application.
CAUTION
• Do not put any compound on the stem.
•
Start with an intermediate-grit compound (120 to 150 grit) and
finish with a fine-grit compound (200 grit or more).
•
Strike the valve several times against the valve seat while rotat-
ing the valve a little at a time.
•
Wash away the compound with diesel fuel.
•
Apply engine oil to the valve contact surface of the valve seat
and rub in the valve and seat well.
•
Inspect the contact pattern of the valve and valve seat again.
•
If the contact pattern is still defective, replace the valve seat.
Inspection: Valve seats
(1) Valve seat width
•
If the measurement exceeds the limit, reface or replace the valve
seat.
•
After refacing or replacing the valve seat, make sure to lap the
valve seat and valve.
(2) Valve sinkage from cylinder head bottom surface
•
Perform measurement keeping the valve in close contact with
the valve seat.
•
If the measurement exceeds the limit, adjust or replace the de-
fective part(s).
•
After refacing or replacing the valve seat, make sure to lap the
valve seat and valve.
