Do the same onboth pins.• Put the pivot + reducing gear assembly in slings (34)• Take out the two Mécanindus pins (30), then remove the two pins (14)• Take the pivot + reducing gear assembly out of the machine• Take the reducing gear (34) off the pivot (1)3 - Installing a reducing gear or hydraulic motor• Ensure that there are rings on the new pivot.• Remount the reducing gear on the pivot with screws and conical washers(see tightening torque values)• Put the pivot+ reducing gear into slings and re-install on the machine.• Put the washers into place (15).• Put the pins back into place and block with new mécanindus pins• Put back the two lubricators and lubricate the pins.• Put back the pivot pin caps and fix with screws and brake washers.• Put back the hydraulic motor and connect the hoses.• Put back the steering bar clevis pin and fix with the screw equipped with agrower washer. Lubricate this pin.NB:When re-installing pins, take the necessary measures to avoid damagingthe pins, rings and bores.4 - Additional operations• Put back the motor and reducing gear (see corresponding sheet).• Put back the wheel (see corresponding sheet).• Put the machine back in the operational configuration.• Make several travel movements to purge the hydraulic circuit.• Check the level of oil in the wheel reducing gear (see correspondingsheet).• Check the level of the hydraulic oil tank.• Lubricate the pins using the lubricators.
