A proper seal ensures smooth operation of the gearbox and helps extend the life of the transmission components. If you notice oil leakage near the gearbox or reduced lubrication inside the housing, the seal may be worn or damaged and should be replaced. Installing a new oil seal helps maintain the correct oil level and protects gears and bearings from contamination. Before installation, disconnect the spark plug wire to prevent accidental starting. Drain the gearbox oil, remove the old seal carefully, and press the new one evenly into place. Refill the gearbox with the recommended oil and check for leaks after reassembly. Wear work gloves to protect your hands during installation. Gearbox oil seal 921-0338 replaces part numbers 112-0800 and 721-0338.
