Valve Dimensions
• Intake and exhaust valves must not be refaced by grinding. Only lapping is permitted.
Risk of injury if exhaust valves with sodium filling are disposed of improperly.
• Cut exhaust valve with sodium filling into 2 parts with a metal saw between shaft center and valve plate. While doing this, do not come into contact with water.
• Throw at the most 10 such sawed exhaust valves in a bucket filled with water and step back immediately.
• When there is contact with water, a sudden chemical reaction occurs which burns the sodium filling.
• The treated parts may then be discarded through conventional disposal channels.
