9.  Loosen the nut in order to release the pressure

on Tooling (B). Remove electronic unit injector

clamp (1) and Tooling (B) from the electronic unit

injector sleeve.

10. Ensure that all of the valves are secured in place

by valve springs, valve rotators and valve keepers.

Rotate the crankshaft through approximately 45

degrees in order to clear  the valves from the

piston. Lightly strike the top of the valves with a

soft faced hammer in order to  ensure that the

valve keepers are properly installed.

End By:

a.  Install the electronic unit injectors.  Refer to

Disassembly and Assembly, “Electronic  Unit

Injector - Install”.
