NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Note:
The following procedure should be adopted in
order to remove the valve springs when the cylinder
head is installed to the engine. Refer to Disassembly
and Assembly, “Inlet and Exhaust Valves - Remove
and Install” for the procedure to remove the valve
springs from a cylinder head that has been removed
from the engine.
Note:
Ensure that the appropriate piston is at top
dead center before the valve spring is removed.
Failure to ensure that the piston is at top dead center
may allow the valve to drop into the cylinder bore.
Personal injury can result from being struck by
parts propelled by a released spring force.
Make sure to wear all necessary protective equip-
ment.
Follow the recommended procedure and use all
recommended tooling to release the spring force.
NOTICE
Plug the apertures for the push rods in the cylinder
head in order to prevent the entry of loose parts into
the engine.
