Re: 1958 FD-12 18 hp drive shaft seal(s)

quote beerman57:

Can I add a question on this subject? When 2 seals are too thick, will one keep the oil in and water out? Prop shafts are the same way – original seals are thick brass, what I call dual-lip, but 2 single lip seals are usually too thick. Will one do both jobs?

Beer, I think you will find the thick CR brass seals were only single lip. So, in theory at least, the new single lip seals would do the same job, assuming the quality is equal. One advantage to the thin seal is you can install it at a different depth and maybe have it ride on an un-worn area of the shaft. Yeah, I still like the old, obsolete CR brass seals. They just seem "right".
