Pressurize the cylinder using compressed air.
NOTE:
If a valve drops into the cylinder, remove the cylinder head. Refer to Cylinder Head - RH or Cylinder Head - LH .
NOTE:
If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations.
