Remove the plug from the flywheel casing using a 16 mm
hex socket key. Fit cranking tool 999 3590 in the hole. Ro-
tate the engine until both valve pairs, on the cylinder head to
be taken out, shut. The rocker bridge should not be loaded
with any of the springs.

Remove the rocker arm bridge and both push rods. Lift and
turn the tappets 1/4 turn until they rest on the guide stud in
the cylinder head, or remove them.
Note: Put all tappets and push rods in a stand or mark them
to make sure that they are returned to their original positions
when reinstalled.

sleeve, fit tool 999 6400 and 999 8007 to the injector and
carefully knock out the injector.

Remove the cylinder head bolts.

Note: Never put the cylinder head on the sealing surface as
