Air Suction Valve Inspection

• Remove the air suction valve (see Air Suction Valve Removal).
• Visually inspect the reeds [A] for cracks, folds, warps, heat damage or other damage.

If there is any doubt as to the condition of the reeds, replace the air suction valve as an assembly.

• Check the reed contact areas [B] of the valve holder for grooves, scratches, any signs of separation from the holder or heat damage.

If there is any doubt as to the condition of the reed contact areas, replace the air suction valve as an assembly.

If any carbon or other foreign particles have accumulated between the reed and the reed contact area, wash the valve assembly clean with a high flash-point solvent.

NOTICE

Do not scrape off the deposits with a scraper as this could damage the rubber, requiring replacement of the suction valve assembly.
