Service Magazine SEPD1246, 28 February 2011, "An Improved Pilot Control Manifold is Now Used on Certain Excavators". Disregard this article. See the article that follows.

Description of Change: The control manifold with an aluminum body has been reworked on certain Excavators.

Adaptable To: A new 369-8371 Selector Spool is used that has a smaller diameter than the former spool. The smaller diameter will help to prevent the spool from seizing. All inventory will be reworked to include the new Selector Spool and a Product Improvement Program (PIP) is available.

Illustration 1	g03384471

The improved control manifold can be identified with "20" on the part number label.
