It seals the shaft bore to keep gear lubricant contained and water out, protecting internal gearcase components from contamination and lubricant loss. The seal is built to meet or exceed the performance of the original equipment part it replaces, making it a reliable choice for gearcase rebuilds, lower unit service, and routine maintenance.\u003c\/p\u003e\u003cp\u003eWith an outer diameter of 1.496 inches (38 mm), a shaft size of 1.063 inches (27 mm), and a width of 0.197 inches (5 mm), the 18-0583 is sized for a specific gearcase bore and shaft combination, so confirming these dimensions against your existing seal or service manual before ordering is recommended.
