64749325 - The seals for the main output shaft [where your front sprocket is] both the inside little and outer large seals available for 750, 860 & 900cc bevel drive twins. This is the larger one on the outside of the shaft. You can access this by removing your counter shaft sprocket, then you can put 2 sheet metal screws adjacent to each other in the existing seal, then pull on the screws with a pair of pliers. I suggest you use a bit of silicone around the outside of the new seal when installing it.
