FEECO recommends replacing both the girth and pinion gears at the same time to avoid the risk of damaging a new gear by pairing it with an old, worn-out gear. Additionally, because the gear is part of the drum's structure and mechanical stability, once the gear has been replaced, a full laser alignment will be needed to realign the drum.
