(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 - Remove" 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 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 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 to prevent the entry of loose parts into the engine.
Illustration 1 g03423086
Follow Step 1.a through Step 1.f to remove the harness assembly for the electronic unit injectors.
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.
Repeat Step 1.a through Step 2 to remove the remaining harness assemblies.
Illustration 2 g01978814
Ensure that the valve spring is compressed squarely or damage to the valve stem may occur.
Follow Step 2.a through Step 2.d to position the appropriate piston at top dead center.
Illustration 3 g03423087
Install Tooling (A) in position on the cylinder head to compress a valve spring (10) for the appropriate cylinder.Note: Ensure that the electronic unit injector label code (12) is not damaged when Tooling (A) is compressed.
Use Tooling (A) to compress valve spring (10) and open the valve slightly.Note: Do not compress the spring so that valve spring retainer (9) touches valve stem seal (11).
Use Tooling (B) to rotate the crankshaft carefully, until the piston touches the valve.Note: Do not use excessive force to turn the crankshaft. The use of force can result in bent valve stems.
Continue to rotate the crankshaft and gradually release the pressure on Tooling (A) until the piston is at the top dead center position. The valve is now held in a position that allows the valve spring to be safely removed.Note: Valve springs must be replaced in pairs for the inlet valve or the exhaust valve of each cylinder. If all valve springs require replacement, the procedure can be carried out on two cylinders at the same time. The procedure can be carried out on the following pairs of cylinders. 1 with 6, 2 with 5 and 3 with 4. Ensure that all the valve springs are installed before changing from one pair of cylinders to another pair of cylinders.
Do not turn the crankshaft while the valve springs are removed.
Apply sufficient pressure to Tooling (A) to allow removal of valve keepers (8).Note: Do not compress the spring so that valve spring retainer (9) touches valve stem seal (11).
Remove valve spring retainer (9).
Slowly release pressure on Tooling (A).
Remove valve spring retainer (9) and remove valve spring (10).
