Repeat the following operations:
•
move cylinder piston 1 (left rear piston)
to TDC;
•
turn the crankshaft 150° in the direction
of engine rotation (direction of travel) in
order to align the hole on the intake
camshaft with the specific hole on the
U bolt; this ensures that all the front
cylinder bank valve springs are decom-
pressed.
•
Refit the camshaft timing setting pin in
the hole in the U bolt on the front head,
and refit the crankshaft timing pin from
the flywheel side, to check that the tim-
ing setting was not altered while the
engine was turned with only one cam-
shaft drive gear fastener screw in
place.
•
Remove the camshaft timing pin.
•
Unscrew and remove the three screws
(1).
•
Remove the U bolt (2) and the oil pipe
