IF YOU USE A DIFFERENT GREASE, YOU CAN CAUSE DAMAGE TO THE BEARINGS. MAKE SURE THAT THE GREASE USED FOR THE AXLE SLEEVE IS THE SAME AS THE GREASE USED FOR THE BEARINGS (CONE AND CAGE). Preparation of the Wheel before Installation. That the seal cap is properly installed and secured with nut andĪ.make sure you are taking the right tire.ī. If the wheel is equipped with a pressure sensor seal cap, make sure (5) Apply a thin layer of COMMON GREASE on the axle protector. (3) Remove the axle nut (7) with the ADAPTOR MLG (2) Remove the nuts (5), the washer (6) and the bolts (8). (1) Remove and discard the cotter pins (4). If you have not these two conditions you must deflate the tire.Ī. – the tire pressure is in the Normal Operating Range – the tire is in the correct condition and NOTE : If you must remove the wheel for access it is not necessary to deflate the tire if: If necessary pressurize the brake accumulator with Yellow pump (Ref. NOTE : On the panel 400VU, make sure that brake pressure indication on the Yellow brake-pressure triple indicator is correct. (1) Make sure that the PARK BRK control switch is set to ON.

(3) Make sure that the wheel chocks are in position.ī. (2) Put the warning notice in the cockpit to tell persons not to operate the landing gear. In this video we will see how to perform an Aircraft wheel change. For all brake types, when the fans are running, the difference ranges typically from approximately 50☌ at 100☌ actual brake temperature up to about 150☌ at 300☌ actual brake temperature. Therefore,Īs soon as the brake fans are running, the indicated brake temperature decreases almost instantaneously. This is because the brake fans are ventilating the brake temperature sensor that is not located inside the material itself. the temperature indicated in the cockpit when the brake fans are running is significantly lower than the temperature indicated when the brake fans are OFF. From the document Proper Operation of Carbon Brakes by Airbus Flight Operations Support: The temperature difference is a measure to correct this anomaly. The fans cool not only the brakes, but also the temperature sensors, at different rates.
