the object being lifted.
Remove Valves as follows:
Remove valves (1, Fig.14) with valve spring
Compress valve springs (3).
Remove spring retainer locks (6).
Remove rotators (5) and oil shields
Allow valve to drop out of guide.
If valve DOES NOT drop out, inspect valve
stem for burrs. If burr exists, remove with a
hone to prevent valve guide damage.
Keep valves in order so reinstallation in
original valve guide is assured.
