target area (5). If the rod is at the edge of the
target area, center the rod in the target area
as follows:
a.
Loosen the nozzle setscrew. A slight
adjustment can then be made to center
the rod within the target area.
b.
Following adjustment, tighten the
setscrew to the specified torque,
15 lb-ft (20 N•m).
Always replace a badly deformed spray nozzle.
Do not attempt to realign it. Precise targeting is
necessary to adequately cool the piston crown.

A blade-type pin is used for alignment of the
flywheel.

REMOVAL
If it is necessary to remove the front cover or
flywheel housing locating dowel pins, do so as
follows:
1. Securely clamp the pin with a pair of locking
pliers.
2. While exerting an outward force, rotate the
pin back and forth until the pin works free
from the hole.
INSTALLATION
Two dowel pins are used to locate the flywheel
housing to the cylinder block. One dowel is round,
the other is a blade type. One end of the blade-
type pin is also round and is the end installed in
cylinder block.
The dowels used for the front cover installation
are similar except for the size. The smaller
dowels are used for the front cover. The larger
dowels are used for the flywheel housing.
