Reply To: Need 1956 Johnson CD-13, 5.5 Hp Lower Unit Seals

[LARRY CATON]

Thanks so much for the video link!

I read the section in the Red book, but was surprised that it didn’t say anything other than it doesn’t need service unless it’s broken.  I’ve already made a bunch of brass shear pins, and have a variety of welders to make the repair if necessary.  I was surprised when I replaced seals on my FD-10 that the factory seals were still in place. I could see over spray of factory paint.  Now I took apart this CD-13, and found the same thing!

All of the bushings, gears, etc. look good on both the CD-13 and CD-15.  I need to put the clutch dogs side by side to see which is in better shape, but at first glance, there’s minimal wear.

I appreciate everyone helping me learn and showing me where to find parts.
