One or more of the above complaints may be caused by a damaged # 20 checkball or checkball seat. The exact complaints will vary depending on how badly damaged the ball and/or plate become.
Replace the # 20 steel checkball with a .218" diameter rubber checkball (part # 116 991 00 29).
If the spacer plate is damaged, it will be necessary to secure a good used plate since new plates are not available separately. Before installing the replacement plate be sure it matches the original exactly.
For more complete valve body information see ATRA Bulletin # 119B.
