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 EN-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.
