1042Re: [j4x-owners-group] Jefa rudder bearing replacement advice
- Oct 10, 2013Bill,
We are now two weeks away from hauling to do the bearing. I am still
trying to figure out how to fit the lip seals. It would seem that I
need to come up with another tube with an inner diameter equal to the
outer diameter of the lip seal. I see in your writeup that this tube
looks integral to the bearing. Did Jefa supply this tube with the
bearing? Mine didn't come with one.
