CAUTION

The EXHAUST valves are sodium filled and should be

handled with care. Use proper protection when

handling a broken exhaust valve.

NOTE

Valves with 100 hours or more will have noticeable

markings on the valve face. This is normal and should

not cause valve leakage. Both valves shown are

acceptable and would not require replacement.
