Warnings

WARNING: given the size and weight of this item, the shipping costs will be 15€ for the outbound and 15€ for the return even if your company has a flat subscription for shipping.

Furthermore, IT IS ADVISED that the MAXIMUM length of the FAP/DPF must be 120cm, in case it is longer, cut the part at the "Cutting Points" provided.

For any FAP/DPF longer than 120cm, extra shipping charges will be applied for both pickup (if done by DIPA) and return.

Finally, to avoid breakages and losses of: temperature probes, lambda probes, various sensors, flanges/brackets, and all components mounted on the FAP/DPF, it is necessary to send the piece without such components; otherwise, we will NOT be able to disassemble them in any way and therefore we will NOT be able to revise the FAP/DPF and will be forced to return the piece UNREVISED.

Typical Errors and Defects

Typical defects:
Soot clogging due to light duty cycles or interrupted regenerations
Reduced engine performance
Warning light on the dashboard

Techinical Info

The OE code Kubota 1J78318251 identifies the diesel particulate filter (DPF) used in the exhaust gas post-treatment system on applications with Kubota engines. It is a component intended for diesel engines in construction, agricultural and industrial machinery, commonly associated with the Kubota V3307-CR-T engine, a 4-cylinder turbocharged common rail diesel of approximately 3,331 cc. The filter is an integral part of the particulate reduction system for the off-road emission configurations of this engine family.

Technical specifications

  • Component type: diesel particulate filter (DPF)
  • Configuration: DOC (catalyst) + DPF
  • Associated engine: Kubota V3307-CR-T
  • Associated engine displacement: 3,331 cc
  • Engine architecture: 4-cylinder turbocharged common rail diesel
  • Typical use: post-treatment systems for construction, agricultural and industrial machines
  • Operation based on accumulation of particulate and subsequent thermal regeneration of the filter

DIPA can intervene to overhaul these components thanks to its experience and expertise.

Functions

  • Traps solid particulate present in the engine exhaust gases
  • Works together with the upstream DOC to promote oxidation of unburnt compounds and to manage system temperatures
  • Enables reduction of solid emissions required to meet off-road emission standards for these machines
  • Operates via controlled regeneration cycles, depending on temperature, engine load and exhaust backpressure
  • Requires correct operation of the engine management system, temperature sensors and the differential pressure sensor
  • Contributes to engine protection and maintaining emission compliance when the regeneration system functions regularly

Model applications

  • KUBOTA M Series

Typical faults

  • Soot clogging due to light duty cycles or interrupted regenerations
  • Reduced engine performance
  • Warning light on the instrument panel

Final conclusions

The Kubota OE 1J78318251 is a DPF intended for the exhaust post-treatment system on Kubota engines.

DIPA can work on this component with a thorough and deep cleaning. Cheaper solutions that add cleaning additives without removing the component (or with only partial disassembly) do not solve the root cause and often prove to be a waste of time and money. Frequently forced regenerations initiated via diagnostic tools are also ineffective. At DIPA we have developed a procedure comprising several intervention phases. The particulate filters undergo a series of decarbonization and purge cycles to remove deposited particles. The result of the process is verified by a series of checks to confirm restored efficiency.
