Fitment can change on a serial-number break within the same model. Send us the model and serial number from the machine nameplate and we verify it against the parts manual before dispatch.
Why this part fails — and what we do differently
Heat rejection is a function of core surface area and airflow — both are easy to get wrong on a hydraulic oil cooler. We build to the original core specification for the Hitachi ZX450H and pressure-test every unit. A core that is 10% undersized holds temperature on a cool day and cooks the engine in summer.
Ordering, packing and warranty
We ship single units worldwide and consolidate full containers for distributors. Every hydraulic oil cooler is individually boxed and labelled with its part number, and pre-shipment photos and dimensional checks are provided as standard. Warranty against manufacturing defect: 6–12 months depending on the part category.
