of 2002. The improved gasket and bolts may also be
used on engines built prior to this date. The new gasket and bolts must be used together. Kit components
are listed in Table 1.

Installation
Install the cylinder head gasket kit as follows:
CAUTION:
To avoid injury from hot surfaces, allow engine
to cool before removing any component. Wear
protective gloves.
CAUTION:
To avoid injury from accidental engine startup
while servicing the engine, disconnect/disable
the starting system.
1. With the engine at ambient temperature and cool to
the touch, refer to the current Series 50 Service
Manual (6SE50 0006 dated June 2000) or Series 60
Service Manual (6SE483 0204 dated April 2002)
and remove the cylinder head and gasket. Follow all
steps to clean, inspect and prepare the cylinder
head for reinstallation.
NOTICE:
Cylinder head mounting bolts are considered
single-use items and must not be reused. Failure
to install new bolts when replacing a cylinder head
may result in improper bolt clamp load, which could
cause gasket failure and severe engine damage.
Discard the former cylinder head mounting bolts.
Former bolts and current bolts must not be mixed,
since this can result in incorrect application of clamp
load. New bolts are identified by the white paint
stripe on the head and the groove across the top of
the head. See Figure 1.

2. Refer to service manual section titled, “Installation of
Cylinder Head.”
With guide studs in place, install the cylinder head
gasket and cylinder head onto the cylinder block.
A. If attachment pages from Service Information
Bulletin 5-50-02 or 16-60-02 have been inserted
into the current Series 50 Service Manual or the
current Series 60 Service Manual respectively, follow all steps on the attachment pages to install
the new cylinder head gaskets and mounting
bolts.
1) Use 26 new bolts (P/N 23530768) for Series
50 heads and 38 bolts for Series 60 heads.
Lubricate the threads and bolt head contact
area of all new bolts with a small amount of
International Compound #2®. Wipe off excess
and install into the cylinder head.
B. If attachment pages from Service Information
Bulletin 5-50-02 or 16-60-02 have not been
inserted into the current Series 50 Service
Manual or Series 60 Service Manual, use the following steps to install the new cylinder head gaskets and mounting bolts:
NOTE: Use of an assembly compound other
than International Compound # 2 may result in
incorrect clamp load.
2) Torque all bolts in the required sequence to
298 N•m (220 lb-ft). See Figure 2 for the Series
50 cylinder head torque sequence or see
Figure 3 for the Series 60 cylinder head torque
sequence.

NOTICE:
Failure to repeat the cylinder head bolt torque
sequence may result in some head bolts losing their
torque when others are tightened, resulting in insufficient clamp load and cylinder head gasket leakage,
which may cause engine damage.
3. After all bolts are torqued to 298 N•m (220 lb-ft),
repeat the torque sequence to verify all of the head
bolts are torqued to specification.
