MOUNTING THE VALVE AND VALVE SPRING
Apply engine oil to the contact surface of each part before
assembly.
Mount each valve securely to the original cylinder position.
Face the cylinder head assembly sideways and insert the intake
and exhaust valves to the valve guides.
The cylinder head assembly can be faced sideways by using
manpower. However, handle it with care because it is a heavy
load.
When reusing the valve, check that the valve stem is free
from damage.
Check that the spring seat (lower) is mounted and place the valve
spring and then spring seat (upper) on the cylinder head.
Insert the valve spring retainer to the hole of the spring seat
(upper).
