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 called out in the service information.
|
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 parts.
|
Cleaning Gasket Surfaces |
• |
Remove all gasket and sealing material from the part using the
J 28410
Remover or equivalent.
|
• |
Care must be used to avoid gouging or scraping the 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 the 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.
|
Assembling Components |
• |
When assembling components, use only the sealant specified or equivalent in the service procedure.
|
• |
Sealing surfaces should be clean and free of debris or oil.
|
• |
Specific components such as crankshaft oil seals or valve stem oil seals may require lubrication during assembly.
|
• |
Components requiring lubrication will be identified in the service procedure.
|
• |
When applying sealant to a component, apply the amount specified in the service procedure.
|
• |
Do not allow the sealant to enter into any blind threaded holes, as it may prevent the bolt from clamping properly or cause component damage when tightened.
|
• |
Tighten bolts to specifications. Do not overtighten.
