Modern diesel aftertreatment is the most common source of derates and unplanned downtime in a contemporary fleet. Ash accumulates in the filter regardless of how well the engine runs, and no amount of regeneration removes it — eventually it must be cleaned or replaced.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.
Modern diesel aftertreatment is the most common source of derates and unplanned downtime in a contemporary fleet. Ash accumulates in the filter regardless of how well the engine runs, and no amount of regeneration removes it — eventually it must be cleaned or replaced.
Progressive derates that reduce the truck to limp mode, forced regenerations that burn fuel and time, and eventually a filter so loaded it cannot be cleaned and must be bought new.
By mileage, typically 150,000 miles, but read the soot and ash load rather than trusting the odometer. Heavy idling loads filters far faster than highway miles.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
