Installation of the DD13 Cylinder Head

Install as follows:
NOTICE: Do not use any abrasive tools or methods to clean oil and coolant counter bores or gasket surfaces of
cylinder head or cylinder block. Foreign material may enter the oil system and cause serious engine damage.
NOTICE: Thoroughly clean oil and coolant counter bores in the cylinder block with a suitable scraper to remove
any foreign material before installation of the cylinder head gasket. Counter bores must be clean and dry. Failure
to properly clean counter bores may result in cylinder head gasket failure.
NOTE: If the coolant seals on the head gasket have failed, do not proactively replace the cylinder liner seals
unless there is evidence of extensive cylinder block erosion.
1. Inspect the cylinder head bolt holes in the cylinder block for the presence of oil, water, dirt, rust or damaged threads.
Clean or re-tap as necessary. Ensure piston domes and cylinder block deck surfaces are clean, dry and free of oil, water
or any other foreign material.

WARNING: PERSONAL INJURY
To avoid injury when removing or installing a heavy engine component, ensure the component is
properly supported and securely attached to an adequate lifting device to prevent the component
from falling.

WARNING: PERSONAL INJURY
To avoid injury, never remove any engine component while the engine is running.

2. Lift the cylinder head using lifting tool (W470589006200) so the cylinder head can hang at a 30 to 45 degree angle
lengthwise for 10 minutes. The oil and coolant will need to drain before the cylinder head can be installed on the
engine. Use caution to avoid damage to the fuel injector tips.

3. Verify that the cylinder liner protrusion heights are within specification prior to installing the cylinder head. Refer to
section "Installation of the Cylinder Liner" for cylinder liner protrusion specifications.
4. Alternate the cylinder head to hang in the opposite direction at the same 30 to 45 degree angle lengthwise for another
ten minutes. Use caution to avoid damage to the fuel injector tips.
5. Clean any oil, water or other foreign material from the cylinder head bolt holes and gasket surface of the cylinder head.
6. Install cylinder head guide studs (W471589016100) into the cylinder block.

NOTE: Be sure both gasket surfaces on the cylinder block and the cylinder head are clean and dry, especially the
oil and coolant counter bores.
7. Position a new cylinder head gasket onto the cylinder block.
8. Lift the cylinder head into position using cylinder head/engine lifting bar tool (W470589006200). Lower the cylinder
head into place over the guide studs and dowel pins until it is fully seated on the cylinder block.
9. Remove the guide studs from the cylinder block.
NOTICE: Do not dip the entire cylinder head mounting bolt in oil as the excessive oil could lead to improper
torque results.
10. Coat the threads and underside of the bolt heads with clean engine oil before installation.
NOTE: If reusing the head bolts, make sure they do not exceed the maximum bolt length of 194 mm (7.638
inches).
11. Using the flywheel and main pulley socket tool (J-45390), install the 38 cylinder head bolts into the cylinder head using
the torque sequence shown below. Torque bolts (1 through 38) in three steps as follows:
a. 200 N·m (147 lb·ft).
b. 90° torque turn.
c. 90° torque turn.
12. Using the illustration shown below, install and torque the small bolts (39 and 40) to 60 N·m (44 lb·ft). For EPA07
DD13, these bolts are located on the outside of the cylinder head casting at the rear of the engine.
