About the Rehlko KDI-TCK 2504U3/26

The Rehlko KDI‑TCK 2504U3/26 is a KDI-series 4-cylinder industrial diesel engine configured for EU Stage V non-road applications. It’s designed for OEMs and operators who need a modern, compact engine platform that supports emissions compliance without sacrificing packaging flexibility or day-to-day service access.

Within the KDI family, the “2504” platform identifies the 4-cylinder architecture, while the “U3/26” designation is the critical detail for matching the correct Stage V build specification and supply package. That matters for both new equipment builds and like-for-like replacement, where the exact variant determines the correct emissions hardware, calibration and installation requirements.

For equipment builders and repower projects, the KDI 2504 platform is typically selected where you need a robust, high-utilisation diesel engine for continuous-duty industrial work, with a modern design that supports reliable operation and practical maintenance in the field. Share your application (duty cycle, installation constraints, and any existing engine plate details) and we’ll help confirm the correct configuration and ancillaries before quoting.

Every engine we supply is set up for its job before it leaves Teignmouth, and backed by the parts and people to keep it running.
