How is hydraulic oil cooled?

On machinery, hydraulic oil is cooled by the oil radiator placed on the return circuit and by the fan blowing through it. To keep it effective, keep the bundle clean, check the fan and its drive, and maintain the recommended oil level and quality. If the oil still overheats, look for an internal pump leak or a misadjusted pressure limiter.

What is the normal temperature of hydraulic oil?

On most machines, hydraulic oil typically operates between 50 and 60�C. Above 80�C, it loses viscosity, oxidizes faster, and wears seals and the pump. The exact range depends on the machine and the oil used: refer to the manufacturer’s manual. A temperature rise during normal operation often indicates a clogged radiator or faulty fan.

Can an oil radiator from another machine fit?

Only if it exactly matches the bundle dimensions, the fittings’ position, and the mounts’ location. In a cooling block, the oil radiator aligns with the water radiator and the air cooler: a few millimeters’ difference prevents fitting. An original radiator taken from the same model avoids these adjustments. Send the reference and serial number to check compatibility.

What is the price of a used hydraulic oil cooler?

The price depends on the machine’s brand and model, the bundle size and design, and whether it is an oil radiator alone or combined with the water radiator. A mini excavator radiator and one for a 972M loader belong to different ranges. The price is provided on request after verifying compatibility with your machine.
