I recently inspected an excavator with a DPF and DEF system. The machine is Tier 4 Final. I inquired about when the DPF had been cleaned last as I didn't know how to find that information in the monitor panel. The owners stated it hadn't been cleaned and nothing indicated that it needed to be cleaned. The machine has just over 5,000 hours on the clock and my question is are the cleaning requirements different now that the diesel exhaust fluid is being used? All the Tier 4 Interim machines had to be cleaned at 4,000 to 5,000 hours of operation.
Thanks for any info.
