NEW TRACK ROLLERS FOR D6 FAMILY MACHINES
New track rollers are available for the following specific machine models:
Elevated Sprocket Tractors D6R, D6H
Track Type Loaders 963C, 963B, 963, 955
Conventional Tractors D6G, D6E, D6D, D6C
Hydraulic Excavators 229, 231
The new track roller is a standardization of ?D6R sized? rollers and may be used with 8.00? pitch (203.2mm) sealed and lubricated, hybrid, heavy duty, rotating bushing, and sealed track but not with SystemOne? track. The new design separates the mounting caps from the seal collar to eliminate flexing in the collars and avoid oil loss. Similar to the D6T SystemOne rollers, these rollers are maintenance free and serviced as a group only.

Part Number Information
On the attached pages are tables of part number information that should be used to select the correct replacement parts for D6R, D6H, D6G, D6E, D6C, D6D, 963C, 963B, 963, 955, 229, and 231 track roller groups, rim assemblies (shells), and shafts. Replacement of track roller groups, rim assemblies (shells) or shafts will be service replaced by an entire track roller group, caps, and hardware.
Roller Group Installation
An issue with the new cap design was recently discovered that could potentially cause the roller to be off center in the track frame. The caps are being redesigned to correct this issue. In the interim, please center the roller between the caps and in the track frame when mounting. A Special Instruction for this procedure will be published in 4th quarter 2007.
