Terex Finlay DEF Delete Emulator for machines fitted with the Caterpillar C4.4 engine. Our plug-and-play solution is designed for compatible Finlay screening and material-processing equipment experiencing DEF, AdBlue, SCR or NOx sensor faults.
If a faulty SCR system is causing warning lights, repeated fault codes or engine derate, our Terex Finlay DEF Delete Emulator provides a compact electronic solution for compatible CAT C4.4 applications.
Important: Terex Finlay engine specifications vary by model, year and emissions standard. This product is specifically for compatible machines fitted with the CAT C4.4 engine and supported SCR system. Please confirm your engine model with us before ordering.
Terex Finlay DEF Delete Emulator for CAT C4.4 Engines
Terex Finlay crushers, screeners and material-processing machines operate in some of the toughest working environments. Dust, vibration, temperature changes and long operating hours can make an SCR system fault particularly disruptive when a machine is required for continuous production.
Our Finlay AdBlue emulator communicates electronically with the machine to simulate the required DEF/SCR system signals on supported CAT C4.4 applications.

- ✅ Plug-and-play installation on compatible machines
- ✅ Helps address DEF/SCR-related derate conditions
- ✅ Supports common SCR and NOx-system fault scenarios
- ✅ No ECU remapping required for supported applications
- ✅ Rugged waterproof emulator
- ✅ Fully reversible installation
- ✅ 2-year warranty

⚠️ Please check before ordering: The same Finlay model can be supplied with different engines depending on production year, country and emissions specification. A model appearing above does not automatically mean every version is compatible.
Send us a photograph of the engine identification plate and machine model/serial information and we can confirm whether your Finlay machine uses the supported CAT C4.4 configuration.
Common Finlay DEF & AdBlue Problems
SCR faults can cause significant downtime on crushers and screening equipment. Problems can originate from several parts of the emissions system, including:
- DEF / AdBlue pump faults
- NOx sensor faults
- DEF injector problems
- SCR system warnings
- DEF quality or level faults
- AdBlue crystallisation
- Wiring or communication faults within the SCR system
- Emissions-related engine derate
When these faults cannot be repaired quickly, the machine may lose power or become unavailable at exactly the time it is needed most.
Why DEF Problems Are Costly on Finlay Equipment
A stationary screening or crushing machine can affect an entire production line. If one machine stops because of an emissions-system fault, excavators, loaders, conveyors and trucks further along the operation may also be left waiting.
This makes reliability especially important for Finlay equipment working in:
- Quarries
- Aggregate processing
- Mining operations
- Recycling facilities
- Demolition sites
- Construction projects
- Remote material-processing sites
How the Terex Finlay DEF Delete Emulator Works
Rather than permanently modifying the engine ECU, the emulator communicates with the machine electronically and reproduces the required signals from the supported SCR/DEF system.
On a compatible CAT C4.4 application, this allows the engine management system to receive the expected SCR information without requiring conventional ECU remapping.
You can learn more about the technology in our technical guide to DEF delete emulators.
Plug-and-Play Installation
Our supported CAT C4.4 solution is designed to make installation as straightforward as possible.
- ✔ No ECU file modification
- ✔ No specialist programming equipment
- ✔ Installation instructions supplied
- ✔ Technical support available
- ✔ Emulator can be removed if the original system is restored
Exact installation procedure can vary according to the Finlay machine and C4.4 emissions configuration, so always follow the instructions supplied for your application.
CAT C4.4 Engine Verification Is Important
Do not order solely from the Finlay machine model. Terex Finlay has used different engines and emissions configurations across different years and markets.
For example, some Finlay models that were previously available with a CAT C4.4 have later been supplied with Caterpillar C2.2, C3.6, Deutz or other engines.
Before dispatch, we recommend confirming:
- Finlay machine model
- Machine serial number
- Engine manufacturer
- Engine model – CAT C4.4
- Engine identification plate
- Current DEF/SCR fault codes where available
This allows us to identify the correct solution before the emulator is shipped.
Built for Harsh Quarry & Construction Environments
Finlay equipment is frequently exposed to dust, mud, vibration and changing weather conditions. Our emulator is housed in a waterproof, rugged enclosure suitable for heavy-equipment applications.
Every unit is supplied with a 2-year warranty and technical support from Blue Removal.

Terex Finlay DEF Delete Emulator FAQ
Does this emulator work with every Terex Finlay machine?
No. This product is specifically intended for supported Terex Finlay machines fitted with the Caterpillar C4.4 engine and compatible SCR system. Finlay has used multiple engine manufacturers and emissions configurations.
Does it work with the Finlay 694?
Selected Finlay 694 configurations use the Caterpillar C4.4 engine, including emissions-controlled versions. Please send us the engine plate before ordering so we can verify your exact machine.
Does it work with the Finlay 696?
Selected Finlay 696 configurations have also been produced with the Caterpillar C4.4. Compatibility depends on the exact engine and emissions configuration, so verification is required.
Does the emulator require ECU remapping?
No ECU remapping is required for the supported plug-and-play CAT C4.4 application.
Is the installation reversible?
Yes. The emulator can be removed and the original system returned to its standard configuration when required.
What warranty is included?
Our Terex Finlay CAT C4.4 emulator is supplied with a 2-year warranty.
