If you notice oil leaking from the sprocket area or grit entering the final drive housing, your B222200000021 seal has likely reached its wear limit. Immediate replacement prevents costly gear damage.
Ensure the rubber O-rings and housing are completely clean and dry. Use an installation tool to apply even pressure. Never use grease on the metal seal faces; use a thin film of clean engine oil instead.
