About the Rehlko KD425/2
The Rehlko KD425‑2 is a robust, space‑efficient air‑cooled diesel engine engineered for practical OEM integration and dependable day‑to‑day operation. Rated at 13 kW (17.4 hp) @ 3600 rpm with 42 Nm @ 2200 rpm, it suits applications that need compact diesel power with a straightforward installation package.
Rehlko specifies a four‑stroke design with integral fan air cooling, direct injection, and electric start, making the KD425‑2 a strong option where simplicity and service access matter. The engine’s 851 cm³ displacement and compact dimensions help it fit into tight equipment bays, while the full‑pressure lubrication system with a full‑flow filter supports consistent long‑term operation in working environments.
As with any OEM engine, the safest way to specify or replace is to match the exact engine code and confirm the installation interfaces (mounting arrangement, intake/exhaust routing, electrical connections, and coupling requirements). If you share your application (pump, compressor, power unit, etc.) and any existing engine plate details, we can help confirm the correct KD425‑2 configuration before ordering.
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.
