Diesel Particulate Filter
(Emission Related
Component) - Clean
Consult your Perkins dealer when the DPF needs to
be cleaned.
The approved Perkins DPF maintenance procedure
requires that one of the following actions be taken
when the DPF needs to be cleaned:
• The DPF from your engine can be replaced with a
new DPF
• The DPF from your engine can be replaced with a
remanufactured DPF
• The DPF from your engine can be cleaned by your
local authorized Perkins dealer, or a Perkins
approved DPF cleaning machine, and reinstalled
Note: To maintain emissions documentation, the
DPF that is removed from the engine when the DPF
is cleaned must be reinstalled on the same engine.
Note: A specific ash service regeneration must be
performed before removing a DPF that will be
cleaned. All three scenarios listed above require a
g03363165
reset of the ash monitoring system in the engine
ECM.
