FMEA Process for Lubrication Failures
For instance, the specific lubricational failure mechanism "particle contamination induced loss of power and work transfer functionality" can cause loss of, or diminished, hydraulic system performance (failure mode) that disable the machine from stamping, molding, etc. 5. Complete the FMEA process as previously discussed.

When the stockpile dozer has a full blade of coal, the volume of coal may fill the draw down hole and reduce the risk. If there is little or no coal in front of the blade, the risk of the dozer going down into the draw down void increases. The dimensions of the dozer and the stockpile height influence the risk.
