Jul 16, 2003 Re Girth Gear Non symetrical girth gears (i.e differing rim thickness) can deform with thermal expansion and result in misalignment during operation. This has been known to occur and can become progressively worse. This problem may not be identified during a cold alignment check. The girth gear cracking usually initiates from a defect in the gear.FEECO recommends replacing both the girth gear and pinion gear 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.
