16 Apply thread lock sealant (1) such as Loctite 277® or
equivalent to the insert OD threads (2).
Figure 6A1 – 511
17 Install the insert and installation driver (1) into the tapped hole by hand only.
18 Start the insert into the threaded hole.
CAUTION
If the insert will not thread down until the
flange contacts the counter-bored surface,
remove the insert immediately with a screw
extracting tool and inspect the tapped hole
for any remaining swarf and/or incorrect
tapping.
19 Install the insert until the flange of the insert contacts the counter-bored surface.
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.
20 Continue to rotate the driver installation tool through the insert.
Figure 6A1 – 512
21 In order to completely form the new threads in the insert, rotate the driver installation tool through the
insert until the mark on the driver installation tool (1)
aligns with the surface of the engine block deck (2).
22 Inspect the insert for correct installation into the tapped hole.
