a. Remove the electronic unit injectors. Refer to
Disassembly and Assembly, “Electronic Unit
Injector - Remove”.
NOTICE
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 Manual, “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.
1. Use Tooling (A) to position the appropriate piston
at the top center position before the valve spring
is removed.
g01284821
Illustration 26
Note: Failure to ensure that the piston is at the top
center position 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 equip-
ment.
NOTICE
Do not turn the crankshaft while the valve springs are
removed.
Follow the recommended procedure and use all
recommended tooling to release the spring force.
Note: Valve springs must be replaced in pairs for the
inlet valves or the exhaust valves 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 of the valve springs are installed
before changing from one pair of cylinders to another
pair of cylinders.
2. Install Tooling (B) in the electronic unit injector
sleeve. Secure Tooling (B) with unit injector clamp
(1).
3. Tighten the nut until valve keepers (3) are loose
on valves (2).
4. Remove valve keepers (3).
5. Loosen the nut in order to release the pressure
