^
Titania 02 sensors use the smaller 12 mm diameter tool: J-43897-12.
3.
Make sure that the tool is clean of all debris from prior usage.
4.
Liberally apply the anti-seize compound, specified in the Parts Information section of this bulletin, into the flutes (see Figure 1) of the thread repair
tool.
CAUTION:
Only use the anti-seize material specified. Other materials may chemically damage the 02 sensor.
5.
Carefully screw the thread repair tool into the exhaust tube, exhaust manifold, or catalytic converter by hand. It needs to be installed until the tool's
taper is fully inserted within the internal thread of the exhaust tube, exhaust manifold, or catalytic converter.
CAUTION:
Ensure the tool goes in straight.
6.
After the thread has been adequately started by hand, a tool such as a socket or wrench can be used to continue the removal of the material.
^
When only light removal of material is needed, screw the thread repair tool in until the cutting surface of the mating surface shave cylinder (see
Figure 1) touches the sealing surface for the 02 sensor. Then turn it one full turn further.
^
When there is a lot of material to be removed, occasionally back off the tool to remove accumulated material from around the tool before
continuing.
CAUTION:
Do not expect the tool to screw in to an absolute stop. The tool's spring and mating surface shave cylinder will rotate until the spring is
completely compressed.
7.
Wipe the threads of the exhaust tube, exhaust manifold, or catalytic converter to remove any debris or anti-seize before replacing the 02 sensor.
NOTE:
If the 02 sensor could not be removed or there is permanent damage to the internal threads, it will be necessary to replace the exhaust tube,
exhaust manifold, or catalytic converter.
8.
Install the 02 sensor and confirm that there is no exhaust leak from the mating surface of the 02 sensor to the exhaust tube, exhaust manifold, or
catalytic converter. If there is leakage, then there may have been permanent damage to internal threads. This would require replacement of the
exhaust tube, exhaust manifold, or catalytic converter.
9.
Completely clean the anti-seize compound and metal debris from the tool to ready it for its next use.
