Tips for new track roller installation
1. Mixing new and old track rollers on the same side can overload the new ones as they sit lower than the worn ones, therefore taking a lot of extra weight.
2. If not replacing all new bottom rollers, it is recommended to fit all the better half on one side and all new ones on the other side. This keeps even pressure on each roller without overloading individual ones.
3. When replacing new roller, do not travel long distances without stopping the machine frequently as they could overheat and seize. Stop every 4-5 minutes and go the opposite direction a little to help circulate the oil. This is standard precaution for the first 100 hours
