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 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.
