To facilitate easy oil sampling, the gear reducers on DDC-Sizers are outfitted with a sample valve on the oil drain port.
To change the oil in the gear reducer, remove the top inspection cover and inspect the internal components for wear, damage or debris. Replace the desiccant filter/breather when changing the oil. This may need to be changed sooner if the desiccant beads turn red, indicating moisture saturation. Fill the gear reducer with the appropriate oil to the fill level indicated on the sight glass. Filling the gearbox with the correct oil and keeping the gearbox clean and maintained is key to long gearbox life.
