( 1 ) The Crankshaft Turning Tool is used on the front pulley.
( 2 ) This Tool is used in the aperture for the electric starting motor.Start By:
Remove the rocker shaft assembly. Refer to Disassembly and Assembly, "Rocker Shaft and Pushrod" for the correct procedure.Note: Either Tooling (B) can be used. Use the Tooling that is most suitable.
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" 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 equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.
Plug the apertures for the push rods in the cylinder head in order to prevent the entry of loose parts into the engine.

Follow Step 1.a through Step 1.h in order to remove the harness assemblies for the electronic unit injectors.
Place a temporary identification mark on connections (1) for harness assembly (3) for electronic unit injectors (2) .
Use a deep socket to remove connections (1) from electronic unit injectors (2) .
Cut cable straps (4) and remove the remaining sections of the cable straps from the cylinder head.
Disconnect plug (6) from harness assembly (3) .
Remove bolt (5) from harness assembly (3) .
Withdraw harness assembly (3) from the cylinder head.
Remove O-ring seal (7) from harness assembly (3) .
Repeat Step 1.a through Step 1.g in order to remove the remaining harness assemblies.

Ensure that the valve spring is compressed squarely or damage to the valve stem may occur.
Follow Step 2.a through Step 2.d in order to position the appropriate piston at top dead center.
Install Tooling (A) in position on the cylinder head in order to compress a valve spring (10) for the appropriate piston.
Use Tooling (A) in order to compress valve spring (10) and open the valve slightly.Note: Do not compress the spring so that valve spri
