Filter**
A Check Engine Indicator or mileage/time intervals indicate when
ash cleaning is required. Use DETROIT Diesel Corporation’s
authorized DPF cleaning procedure. Failure to follow this
procedure could result in engine and/or aftertreatment damage,
causing degraded vehicle performance including excess fuel
consumption and decreased engine life.
Normal DPF ash clean interval is every 150,000 miles (241,000
km) (5,000 hrs)*
DEF Pump Filter
Replace every 500,000 miles (805,000 km) (10,000 hrs) (3 years)*
Air Compressor
Inspect every 55,000 miles (88,000 km) (1,800 hrs) (18 months)*
*Whichever comes first. Note: Reaching the Davco change line supersedes these intervals.
**Detroit highly recommends exchanging the DPF with a Detroit™ genuine DPF to ensure
maximum life.
• Currently, only Detroit™ Fuel Filter/Water Separator & Davco 245 or Racor 6600 are the
only frame-mounted filtration systems compatible for Detroit™ Engines.
• Refer to "Routine Preventive Maintenance" for a description of all items.
