UNDERCARRIAGE

UNDERCARRIAGE GP

2009/07/06 The Undercarriage Has Been Changed To Camber Only {4150}

Track-Type Tractor:
D9N (S/N: 1JD1-UP; 5FJ1-UP; 6XJ1-UP)
D9R (S/N: JJB1-UP; ABK1-UP; ACL1-UP; 7TL1-UP; 8BL1-UP; WDM1-UP)
D9T (S/N: RJS1-UP)

Description of Change: The undercarriage has been changed to camber only on the D9R and the D9T. The new camber only undercarriage will perform better in applications that have high abrasion and applications that have low abrasion. This replaces the camber/toe/yaw undercarriage that was optimized for high abrasion applications.

Adaptable To: This change is effective with the following machines:

D9R (S/N: WDM1740-UP)
D9T (S/N: RJS1395-UP)

This change is adaptable to the following machines:

D9N (S/N: 1JD1-UP; 5FJ1-UP; 6XJ1-UP)
D9R (S/N: JJB1-UP; ABK1-UP; ACL1-UP; 7TL1-UP; 8BL1-UP; WDM1-1739)
D9T (S/N: RJS1-1394)

The straight undercarriage factory attachment that was previously offered for low abrasive or for forward travel applications is discontinued.

Tractors with camber/toe/yaw undercarriages will continue to need one long equalizer bar with left and right minor bogies and camber/tow/yaw rear track roller frames unless the undercarriage is fully converted.

Short equalizer bars with straight minor bogies are compatible with straight or camber only frames.
