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 49485 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. | 
 
Caution: Refer to Fastener Caution in the Preface section.
|     •  | Tighten bolts to specifications. Do not overtighten. |
