Cylinder Head - Installation

INSTALLATION - CYLINDER HEAD

NOTE: The Cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolts must be replaced (Figure 1).

Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale, the bolt should be replaced.





Figure 1 Checking Bolts for Stretching (Necking)






1. Before installing the bolts, the threads should be coated with engine oil.
2. Position cylinder head gasket on engine block (Figure 2).
