Reuse of gasket and application of sealant
|
|
•
|
Do not reuse gaskets unless specified otherwise.
|
|
•
|
Gaskets which can be reused are identified in the service procedure.
|
|
•
|
Do not apply sealant to any gaskets or sealing surfaces unless stated otherwise in the service information.
|
|
•
|
Use a rubber mallet to separate components.
|
|
•
|
Strike the parts from the side to loosen the components.
|
|
•
|
Strike near to hooks or reinforced areas to prevent the parts becoming warped.
|
|
Cleaning of gasket surfaces
|
|
•
|
Remove all gaskets and sealing material from the component using the
J 28410
removal tool or equivalent.
|
|
•
|
Take care not to scratch or scrape the sealing surfaces.
|
|
•
|
No other method or technique may be used to remove sealant or gasket material from a component.
|
|
•
|
Do not use abrasive paper, sandpaper or power tools to clean the sealing surfaces.
|
|
|
-
|
Such cleaning methods may damage the component's sealing surfaces.
|
|
|
-
|
Abrasive paper can also generate a fine grit which the oil filter cannot remove from the oil.
|
|
|
-
|
This grit can have an abrasive effect and can cause internal damage to the engine.
|
|
•
|
During assembly of components, only the sealant specified in the service procedure or equivalent may be used.
|
|
•
|
Sealing surfaces must be clean and free from dirt and oil.
|
|
•
|
Special components such as the crankshaft's oil seals or valve spindle oil seals may require lubrication during assembly.
|
|
•
|
Components which require lubrication are identified in the service procedure.
|
|
•
|
When sealant is placed on a component, the quantity specified in the service procedure must be used.
|
|
•
|
Do not allow sealant to get into threaded holes as this can cause the screw not to be secured properly or cause component damage when it is tightened.
|
|
•
|
Tighten the screws to the specified torques. Do not tighten them too hard.
