Clean
1 Remove all thread sealant, gasket material or sealant using a commercially available plastic or wood scraper.
2 Clean all the following areas with a suitable solvent:
• sealing surfaces,
• cooling passages,
• oil passages, and
• bearing journals.
3 Clean all threaded and through holes with a suitable solvent.

Safety glasses must be worn when using
compressed air.
4 Dry the engine block with compressed air.
Inspect
Visual Inspection
NOTE
The following procedure assumes the engine has
been disassembled and cleaned, as described
above.
1 Inspect the crankshaft bearing journals for damage or spun bearings. The crankshaft bearing journals are not
repairable and if damage is f ound, the cylinder block assembly must be replaced.
2 Inspect the primary camshaft chain t ensioner mounting surface on the engine block for burrs or any defects that
would affect the sealing of the new primary camshaft chain tensioner gasket.
3 Inspect all sealing and mating surfaces for damage, repair or replace the cylinder block assembly if required.
4 Inspect all threaded and through holes for damage or excessive debris.
5 Inspect all bolts for damage, if damaged replace with new bolts only.
6 Inspect the cylinder walls for cracks or damage. The cyli nder sleeves are not serviced separately, if the cylinders
are damaged the cylinder block assembly must be replaced.
7 Inspect the engine block for cracks. Do not repair any cra cks. If cracks are found, the cylinder block assembly must
be replaced. Repair any damaged threaded holes, refer to 4.9 Thread Repair Specifications.
Measuring Cylinder Bore Diameter
1 Measure the cylinder bore diameter 37 mm from the
deck face (1) using a commercially available bore
gauge or Tool No. J-8087 (2).
2 Record the results and compare with the dimensions listed in the specifications, refer to 5 Specifications.

NOTE
If the cylinder diameter exceeds the
specifications, the cylinder block may be
oversized to 0.25 mm. Only one size of
oversized pistons and rings are available for
service. If the cylinder bore diameter exceeds
specification by mo re than 0.25 mm, the
cylinder block must be replaced.

NOTE
All swarf must be removed from the tapped hole
prior to insert installation.

Safety glasses must be worn when using
compressed air.
9 Using compressed air, clean out any swarf.

NOTE
Do not allow oil or other foreign material to
contact the outside diameter (OD) of the insert.
10 Lubricate the threads of the driver installation tool (2)
with the driver oil (1).

NOTE
The driver installation tool will tighten up before
cutting completely through the insert. This is
acceptable. The threads at the bottom of the
insert are being formed and the insert is
mechanically locking the insert into the base
material threads.
15 Continue to rotate the driver installation tool (1) through the insert (2)
16 Remove the driver installation tool.

Figure 6A1 – 569
17 Inspect the insert for co rrect installation into the
tapped hole. A correctly installed insert (1) will be
either flush or slightly below flush with the surface of
the base material (2).

Figure 6A1 – 570
18 Any installed insert that restricts or blocks an oil or
engine coolant passage (3) will need to have the oil or
engine coolant passage drilled out (4) to the original
size of the oil or engine c oolant passage. After drilling
the restriction or block age, clean out any swarf and
thread the installation driver tool through the insert
again to remove any burrs caused by the drilling of
the oil or engine coolant passage.
