Start by removing the rocker shaft assembly. Refer to Disassembly and Assembly, 'Rocker Shaft and Pushrod - Remove'.

WARNING: Personal injury can result from being struck by parts propelled by a released spring force. Make sure to wear all necessary protective equipment. Follow the recommended procedure and use all recommended tooling to release the spring force.

NOTICE: Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life.

NOTICE: Install suitable plugs to the inlet ports of the cylinder head in order to prevent the entry of loose parts into the engine.

NOTICE: Plug the apertures for the push rods in the cylinder head in order to prevent the entry of loose parts into the engine.

Note: The removal procedure is similar for the three cylinder and the four cylinder engines. The following procedure should be adopted to remove the valve springs when the cylinder head is installed to the engine.

Note: Ensure that the appropriate piston is at the top center position before the valve spring is removed. Failure to ensure that the piston is at the top center position may allow the valve to drop into the cylinder bore.

Did you follow Steps 1.a through 1.d to position the appropriate piston at top center?

Did you install Tooling (A) and (B) in position on the cylinder head to compress a valve spring for the appropriate piston?
