The following 2 types of sealer are commonly used in engines:
• | The anaerobic gasket eliminator sealer |
Follow the service procedure instructions. Use the correct sealer in
the proper place in order to prevent oil leaks. Do not interchange the
2 types of sealers. Use the sealer recommended in the service
procedure.
Applying RTV Sealer
• | Do not use the room temperature vulcanizing (RTV) sealant in areas
where extreme temperatures are expected. These areas include the following
locations: |
- | The other surfaces where gasket eliminator is specified |
• | Use a rubber mallet in order to separate the components sealed
with RTV sealant. Bump the part sideways in order to shear the RTV sealer.
Perform the bumping at the bends or the reinforced areas in order to
prevent distortion of the components. The RTV sealant is weaker in shear,
lateral, strength than in tensile, vertical, strength. |
| Important: Do not use any other method or technique in order to remove the gasket
material from a component.
|
• | Do not use the following items in order to clean the gasket surfaces: |
These methods of cleaning may damage the part.
Abrasive pads also produce a fine grit that the oil filter cannot remove
from the oil. This grit is abrasive and may cause internal engine damage.
• | Remove all of the gasket material from the component using a plastic
or a wood scraper. Use Loctite® brand gasket remover P/N 4MA
or the equivalent. Follow all of the safety recommendations and the directions
that are on the container. |
| Important: Do not allow the sealer to enter the blind threaded holes. The sealer
may cause the following conditions:
|
- | Prevent you from properly seating the bolt |
- | Cause damage when you tighten the bolt |
• | Apply the RTV sealant to a clean surface. Use a bead size as specified
in the procedure. Apply the bead to the inside of any bolt holes. |
• | Assemble the components while the RTV sealant is still wet, within
3 minutes. Do not wait for the RTV sealant to skin over. |
| Important: Do not overtighten the bolts.
|
• | Tighten the bolts to specifications. |
Applying Anaerobic Sealer
The anaerobic gasket eliminator hardens in the absence of air. This
type of sealer is used where 2 rigid parts, such as castings,
are assembled together. When 2 rigid parts are disassembled and
no sealer or gasket is readily noticeable, the parts were probably assembled
using a gasket eliminator.
Important: Do not use any other method or technique in order to remove the gasket
material from a component.
Do not use the following items in order to clean the gasket surfaces:
These methods of cleaning may damage the part.
Abrasive pads also produce a fine grit that the oil filter cannot remove
from the oil. This grit is abrasive and may cause internal engine damage.
• | Remove all of the gasket material from the component using a plastic
or a wood scraper. Use Loctite® brand gasket remover P/N 4MA
or the equivalent. Follow all of the safety recommendations and the
directions that are on the container. |
• | Apply a continuous bead of the gasket eliminator to 1 flange.
Clean and dry any surfaces that you will reseal. |
| Important: Anaerobic sealed joints that are partially torqued and allowed to cure
more than 5 minutes may result in incorrect shimming and sealing
of the joint.
|
• | Do not allow the sealer to enter the blind threaded holes. The sealer
may cause the following conditions: |
- | Prevent you from properly seating the bolt |
- | Cause damage when you tighten the bolt |
• | Spread the sealer evenly in order to get a uniform coating on
the sealing surface. |
• | Tighten the bolts to the specifications. |
• | Remove the excess sealer from the outside of the joint. |
