Steps to a Leak-Proof Cover

Ensuring the cover does not leak is not complicated, but does require some care.

• clean off any traces of the old gasket. if necessary use a utility knife blade. Be careful not to gouge the (soft) brass
• check that the cover is perfectly flat (ie. not bent or warped) but laying it against the edge of a ruler
• remove any scoring or burrs (defects in the metal) with emery paper
• sometimes the cover can be reversed if one side becomes too badly scored
