Description of Change: Final drives are leaking from the Duo-Cone Seal. Abrasive particles of dirt or sand can prematurely wear out the sealing surfaces of the Duo-Cone Seal. This will then lead to the failing of the final drive when the oil level is low.Adaptable To: When you disassemble the final drive on the machines that are listed, rebuild the final drive with a 6Y-0859 Duo-Cone Seal Gp (Heavy Duty). This Duo-Cone Seal will be more tolerant to abrasive applications.
