CAUTION: Wear safety glasses in order to avoid eye
damage.
1. Determine the size, pitch and depth of the damaged
thread. If necessary, adjust the stop collars on the
cutting tool and tap to the required depth.
2. Drill out the damaged thread. Clean out any chips.
3. Avoid any buildup of chips. Back out the tap every
few turns and remove the chips.
4. Tap the hole. Lubricate the tap with light engine oil.
Clean the thread.
5. Thread the insert onto the mandrel of the installer.
Engage the tang of the insert onto the end of the
mandrel.
IMPORTANT: The insert should be flush to one turn
below the surface.
6. Lubricate the insert with light engine oil (except
when installing in aluminum) and install the insert.
7. If the tang of the insert does not break off when
backing out the installer, break the tang off with a drift.
Cleanliness and Care
• Throughout this section, it should be understood that
proper cleaning and protection of machined surfaces
and friction areas is part of the repair procedure. This
is considered standard shop practice even if not
specifically stated.
• When any internal engine parts are serviced, care
and cleanliness is important.
• When components are removed for service, they
should be marked, organized or retained in a specific
order for reassembly. Refer to Separating Parts.
• At the time of installation, components should be
installed in the same location and with the same
mating surface as when removed.
• An engine is a combination of many machined,
honed, polished and lapped surfaces with tolerances
that are measured in millimeters or thousandths of
an inch. these surfaces should be covered or
protected to avoid component damage.
• A liberal coating of clean engine oil should be applied
to friction areas during assembly.
• Proper lubrication will protect and lubricate friction
surfaces during initial operation.
Replacing Engine Gaskets
1. Gasket reuse and applying sealants:
• Do not reuse any gasket unless specified.
• Gaskets that can be reused will be identified in the
service procedure.
• Do not apply sealant to any gasket or sealing
surface unless specified in the service procedure.
2. Separating components:
• Use a rubber mallet to separate components.
• Bump the part sideways to loosen the components.
• Bumping should be done at bends or reinforced
areas to prevent distortion of the parts.
3. Cleaning gasket surfaces:
• Remove all gasket and sealing material from the
part using a plastic or wood scraper (if required).
• Care must taken to avoid gouging or scraping the
aluminum sealing surfaces.
• Do not use any other method or technique to
remove sealant or gasket material from a part.
• Do not use abrasive pads, sand paper or power
tools to clean gasket surfaces.
- These methods of cleaning can cause damage
to the component sealing surfaces.
- Abrasive pads also produce a fine grit that the oil
filter cannot remove from the oil.
- This grit is abrasive and has been known to
cause internal engine damage.
