Track Roller Break In Procedure
This procedure provides a break in period for the track rollers, carrier rollers, and idlers. This procedure must be performed at machine commissioning and when track rollers, carrier rollers, and idlers have been replaced or overhauled. This procedure supersedes all previous published documents and recommended practices.
A 123-6700 Infrared Thermometer II, or equivalent, is required to monitor component temperatures when performing this procedure.
When performing track roller break in, do the following:
-
- * Raise the boom to maximum height.
- * Retract the stick.
- * On front shovels, curl the bucket out.
- * On mass excavators, curl the bucket in.
- * Travel on a level surface.
- * If a level surface is unavailable for twenty minutes travel time, travel with the sprocket facing in the downhill direction.
- * Raise the boom to maximum height.
1. Travel the machine in the forward direction (front linkage over the idler) for twenty minutes. Monitor the temperatures of the components several times while the break in procedure is being performed. The temperatures of the components should not exceed 70°C (158.0°F). Check the temperatures at the roller flanges, as close to the seal as possible. Check the temperatures at the ends of the shafts.
2. Stop the machine after twenty minutes of travel. Check the temperatures of the components. Inspect the seals for oil leaks.
3. If necessary, allow the components to cool before proceeding.
4. Travel the machine in the reverse direction (front linkage over the sprocket) for twenty minutes. Monitor the temperatures of the components several times while the break in procedure is being performed. The temperatures of the components should not exceed 70°C (158.0°F). Check the temperatures at the roller flanges, as close to the seal as possible. Check the temperatures at the ends of the shafts.
5. Stop the machine after twenty minutes of travel. Check the temperatures of the components. Inspect the seals for oil leaks.
6. If necessary, allow the components to cool before proceeding.
7. Repeat Steps 1 through 6.
Travel Procedure
This procedure prevents overheating of the track rollers, carrier rollers, and idlers when moving the machine over long distances. This procedure supersedes all previous published documents and recommended practices.
A 123-6700 Infrared Thermometer II, or equivalent, is required to monitor component temperatures when performing this procedure.
-
- * When traveling the machine over a long distance, do the following:
- * Raise the boom to maximum height.
- * Retract the stick.
- * On front shovels, curl the bucket out.
- * On mass excavators, curl the bucket in.
- * When traveling the machine over a long distance, do the following:
1. Travel in the forward direction (front linkage over the idler) except when traveling downhill. When traveling downhill, position the sprocket on the downhill side.
2. Monitor the temperatures of the components several times while the machine is traveling. The temperatures of the components should not exceed 70°C (158.0°F). Check the temperatures at the roller flanges, as close to the seal as possible. Check the temperatures at the ends of the shafts.
3. Stop the machine after twenty minutes of travel. Check the temperatures of the components. Inspect the seals for oil leaks.
4. If necessary, allow the components to cool before proceeding.
