  The part that fails is the bottom end bearing. They will usually last over 50 hours and I have seen them last more than 100. I have also seen them not last more than 10 hours. You can inspect it and measure the tolerances but sometimes there are no signs as to when it will fail. It is a pretty good idea to replace it after 50 hours.

  So can just the bottom bearing be replaced then?

    There is a rod kit that includes the bottom end bearing. You probably want to have it done by someone with the right tools and the know how to do it right.

  Thanks Curtis, so is that a definitive no on each of the points I have asked?
  
  I understand they have the rod kit, but I am looking for clarification on the questions asked if possible.

  Sorry, David. I didn’t mean to be so vague. The bottom end needle bearing by itself is not available from Rotax. They probably recommend changing the rod when you change the bottom end bearing. I am sure if you tried hard enough you could get the bottom end bearing. I am pretty sure Rotax doesn’t manufacture the bearing themselves.
