7. Replacing core plugs
|
First punch a hole into the plug in the centre where it will be weakest from corrosion |
|
Use an old screwdriver or thin chisel to lever it out |
|
Here you can see the corrosion to the plug and round the casting |
|
Use a wire cup brush in an electric drill to thoroughly clean out the casting |
|
Put a little Locktite or similar sealant round the edge of the hole like this |
|
Drop in the core plug |
|
and hit it firmly in the centre until a good dimple is formed - make sure the plug stays at the bottom of the hole during the process |
|
Should
look like this when you have finished - do the other three the same way.
