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 a scraping tool. |
| • | 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. |
