b. Use measurements obtained
and limits given in the
table as a guide to deter-
mine the advisability of
reinstalling the head on
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, refer to Direct
Support Maintenance.
NOTE
Resurface both heads together.
NOTE
If one head is refaced, the
other head should be resurfaced.
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 reinstalled into the
engine.
