NOTE : The gearbox is a unit filled with grease and is not a hermetically
____ sealed unit. It is normal for this grease to have some oil separation. The external surfaces of the gearbox may be moist with this separated oil as it is not a sealed unit. However, any separated oil in the unit that touches the grease will be changed back during operation. The oil separation will decrease during in-service operation until the lubricant is in a condition that is stable. This is normal and will not cause damage to the unit.
