Service Magazine SEPD1039, 19 November 2009, "Improved Track Rollers Are Now Used On the D10T". Disregard this article. See the replacement article that follows.

Description of Change: Improved track rollers are now used on the D10T. The improved track rollers are also available for the D10N and D10R. The improved track roller now has two additional bolts for retention that will increase the durability of the track roller. This change reduces the occurrence of oil leaks from the track roller. The former shaft, the collar, and the thrust washer can be used with a new shell, a new retainer, and the additional bolts. The former groups are cancelled and replaced by the new design.

Adaptable To: The improved track roller groups are effective with the following machines:

  • D10T (S/N: RJG2089-UP)

The improved track roller groups are adaptable to the following machines:

  • D10N (S/N: 2YD1-UP; 3SK1-UP)

  • D10R (S/N: 3KR1-UP; AKT1-UP)
