DESCRIPTION & OPERATION
Page 41
Cylinder Head
The cast iron cylinder head (Figure 43) is
constructed using a special iron alloy. The head
contains cored inlet, exhaust and coolant
passages, drilled oil passages, replaceable inlet
and exhaust guides and seats, various drilled
passages and tapped holes. Each cylinder head
covers three cylinders and has two inlet and two
exhaust valves per cylinder. Circular grooves
correspond with the fire ring bead on the cylinder
sleeves. This design sets the fire ring over the
liner. With the cylinder head installed and the
bolts tightened to specification, the liner coining
bead extrudes the fire ring into the cylinder head
groove, providing a positive combustion pressure
seal.
