Fuel Injector Removal
The fuel injector installed position and mounting pressure are maintained by
a twin hold down fixture (one hold down fixture for every two fuel injectors).
The twin hold down fixtures are bolted to the
cylinder head with spring washers, the correct
mounting pressure is ensured by the contact
pressure of the spring washers.
The high pressure fuel injectors are positioned on
the intake side at a 30º angle to the cylinder head
and reach directly into the combustion chamber
between the two intake valves.
• Remove the fuel rail and disconnect plug con-
nections (1).
• Remove bolts (3), nozzle holder (4), spring
washers (2) and store exactly as removed for
re-installation.
• Install special tool #13 1 430 and 13 5 250 on
injector nozzles and drive out by slide ham-
mering.
