Signs Your Caterpillar DPF May Need Inspection or Replacement
A diesel particulate filter may require inspection, cleaning, diagnosis or replacement when excessive ash accumulation, soot loading, restriction or physical damage prevents the aftertreatment system from operating correctly.
- Frequent, incomplete or unsuccessful regeneration cycles
- Excessive soot loading, ash accumulation or visible face plugging
- Abnormal DPF differential-pressure readings
- High exhaust backpressure
- DPF restriction, soot-capacity or filter-efficiency diagnostic trouble codes
- Visible soot at the tailpipe that may indicate internal filter damage
- Reduced engine performance under load
- Cracking, melting, corrosion or other physical filter damage
These symptoms may have multiple causes. Diagnose the complete engine and exhaust aftertreatment system before replacing the DPF.
