Test objectives were to determine 1 the durability of the arctic track and wide sprocket wheel, 2 the mobility of the M551 vehicle when equipped with the arctic track with and without pads, 3 whether the arctic track andor the wide sprocket wheel result in any degradation to the basic vehicle, and 4 parts failure data on components of the M551 facility vehicle other than that related to the wide sprocket wheels and track. Arctic track was assembled and installed by the crew in 28.0 man-hours. Two sets of wide sprocket wheels were installed by organizational mechanics in 1.5 man-hours each. All basic issue items and organizational tools were adequate for the installation. The test items had no significant effect on the fuel consumption rate of the M551 vehicle. No failures of the test sprocket were experienced. It was concluded that the test wide sprocket wheel is significantly more durable and has a greater service life than does the standard sprocket.
