Diesel Particulate Filter Maintenance and
Service
The Exhaust Filter includes the Diesel Oxidation Catalyst
and Diesel Particulate Filter (DPF). The DPF is designed
to retain residual ash, which is a noncombustible result
of additives used in crankcase lubrication oils and the
fuel. The DPF provides many hours of maintenance free
operation. At some point the DPF will require professional
service to remove the accumulated ash. The exact
number of hours of operation before service is required will
vary depending upon the engine’s power category, duty
cycle and operating conditions, engine oil ash content,
and fuel quality. Adhering to John Deere’s recommended
oil and fuel specifications will maximize the hours of
operation before professional DPF service is required.
As the engine owner, you are responsible for performing
the required maintenance described in your Operator's
manual. The exhaust filter's dash lamp indicator or the
diagnostic codes will indicate when the DPF needs ash
removal service. Generally, the ash removal service
interval will far exceed the EPA required minimums of
3,000 hours for engines below 175hp/130kW and 4,500
hours for engines at or above 175hp/130kW.
The removal of DPF ash must be done by removing the
DPF from the machine and placing it into specialized
equipment. Do not remove ash by using water or other
chemicals. Removing ash by these methods may damage
the material securing the DPF in its canister, resulting
in the loosening of the DPF element in the canister and
subjecting it to damage from vibration.
Failure to follow the approved ash removal methods may
violate U.S. federal, state and local hazardous waste
laws, along with damage to the DPF resulting in potential
denial of the Diesel Exhaust Filter emissions warranty. It is
strongly recommended you take the DPF to an authorized
John Deere service location or other qualified service
provider for servicing.
Exhaust Filter — Diesel Particulate Filter Ash Handling and Disposal
CAUTION: Your Governing Bodies Regulations
may classify diesel particulate filter ash as a
hazardous waste. Hazardous wastes therefore
must be disposed of in accordance with all
applicable Governing Bodies Regulations
governing hazardous waste disposal. Only a
qualified service provider should remove ash
from the DPF. Personal protective equipment and
clothing, maintained in a sanitary and reliable
condition, should be used when handling and
cleaning a DPF. See your John Deere dealer or
qualified service provider for assistance.
Exhaust Filter — Disposal
CAUTION: Proper management of an Exhaust
Filter that has reached the end of its useful life
is required, since the ash or catalyst material
in the device may be classified as hazardous
waste under federal, state, and/or local laws
or regulations. See your John Deere dealer or
qualified service provider for assistance.
