Seal on my Mojo is pouring water. I pulled the dripless seal off. The rubber inside the brass is worn causing the water to come out. My question, in all the images I have seen, there is always a collar that secures to the shaft, and that collar rests against the brass on the seal. Mine is just the brass piece with a barb fitting on it. Am I missing something?

Also, is there a bushing or anything inside the shaft log?
