It depends on the tube you are using on your midcase.

I am not sure if the early 16800 had a 702 crown and tube.

This 702 crown is specific of the 5512/3/4/7 and after service it is replaced by an improved crown and tube combo : the 24-703-0 which is more reliable in term of water resistance

Not sure if the 16800 came with a 702 or 703 tube back in the days.


Good move to differentiate a 702 from a 703 is the threads inside the crown. The 703 has a gasket (or o-ring) on the outside and the threads of the crown stops to fit the o ring.

The 702 has inside of it threads from the top to the bottom.

I hope it is clear :/

The stem isn't a issue it can be replaced from the crown most important thing is the crown, and the threads on this one looks like it is a 24-702-0 crown
