Description of Change: Improvements have been made to the materials and the manufacturing process of the hoses that are listed in Table 1. A new process for winding wire has been implemented in order to produce a more consistent wire lay. A new superior rubber compound provides better adhesion between the wire plies.

Improved Hoses
Part Number	Part Name	Description
161-1837	Hydraulic Hose	XT-6 ES 31.75 mm (1.25 inch)
161-1838	Hose	XT-6 ES 38.10 mm (1.5 inch)
245-1412	Hose	XT-6 ES ToughGuard 31.75 mm (1.25 inch)

Adaptable To: These improvements are effective on bulk hose with manufactured date codes of 2010 (D-MMM-YY printed on the hose opposite to the layline). These are shipped with a round, green colored sticker labeled "Improved XT6 Hose" on the packaging for identification during the first part of 2010.
