Service Magazine, SEPD0989, 27 April 2009, "New Improved Pressure Reducing Valves and Shuttle Valves are Now Used on Certain Excavators". Disregard this article. See the article that follows.

A new 259-7733 Connector, 3J-1907 O-Ring Seal and a 6V-8397 O-Ring Seal replaces the former 148-8336 Connector As. The new part eliminates any vibration during a slight swing of the machine to the right.

Note: Tighten the connector to a torque of 35 ± 4 N·m (26 ± 3 lb ft).
