After changing the front bevel drive to Steve's new 7th gear mod on Tom's Connie I noticed that it has a very small oil leak around the shifter shaft seal. It didn't leak on Paul's bike so I must have nicked it while swapping the units. Is this as easy as it looks to change? Just drill a small hole in the face of the seal and pull it out with a sheet metal screw? From what I recall the seal cannot be pushed all the way into the casing due to the design of the housing right? Roger COG 5903 Virginia Beach, VA
