b. Use the measurements
obtained and the
limits given in the
table as a guide to
determine the advise-
ability of reinstal-
ling the head of the
engine or of refacing
it. The number of
times a cylinder head
may be refaced will
depend upon the amount
of stock previously
removed.
c. If the cylinder head
is to be refaced, re-
fer to Direct Support
Maintenance.
CAUTION
When a cylinder head has been refaced, critical dimensions
such as the protrusion of valve seat inserts, exhaust valves,
injector tubes and injector spray tips must be checked and
corrected. The push rods must also be adjusted to prevent the
exhaust valves from striking the pistons after the cylinder
head is re-installed in the engine.
