The old seals in my helm fell apart when I pulled the shaft out so I wasn’t able too use them as a guide to put the new ones back in the correct sequence. I was able too figure it out by trial and error. The parts did fit good and I would buy again. It would help a little if this kit came with a diagram showing sequence of instillation.
