About the Rehlko KDI‑M2504EA/26
The Rehlko KDI‑M2504EA/26 (KDI‑M 2504 EA) is a compact 4‑cylinder industrial diesel engine designed for equipment builders and operators who need dependable performance in a space-efficient package.
Rehlko positions the KDI platform around delivering more power and torque in a smaller frame, helping OEMs and fleet operators optimise installation space without compromising capability.
This engine class is commonly specified for pumps, compressors, hydraulic power units, construction equipment and agricultural machinery, where reliability, service access and long-term parts support are critical. If you’re replacing an older engine or designing a new power unit, the KDI 2504 family is often selected to balance packaging, performance and maintainability.
To ensure the correct build for your application, we can help confirm the right configuration for your duty cycle, installation constraints and target market requirements. Request a quote with your machine type, load profile and operating environment, and we’ll recommend the best-fit specification and supply route.
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.
