Rick, WAYYYYY back at AQ school I was told not to use perfect seal or Aviation seal, I think they're the same, on the o rings. Just good ol' blue wheel bearing grease.
Yes, pretty much the same here. Just the good ole green wheel bearing grease.
However...................
I guess if you've been using perfect seal all these years and I've been doing the grease we both learned something new.
Once I started getting back into these drives of age, I started seeing what happens to the grease. You've certainly seen the whitish powdery looking crap.... especially on salt water boats.
I've torn many drives down with that brown stuff everywhere and just cussed at it.
Yep.... a real mess... but, no where near as much to deal with as is rust/corrosion.
Solvents, heat, scraping tools, and the ole wire wheel take care of the brown goop quickly.
The only place I do use aviation sealant is under and above the hose nipple on the beaded gasket.
The bead itself gets greased...... the upper side can be sealed to the water neck face.
And while on topic, and for those reading....... a new beaded gasket will fail shortly if the upper pivot tube bushing is wearing out. It will seal in the beginning..... but will eventually loose resiliency and then loose it's seal against the pivot tube.
I've never put anything on the "blue seal".
What is the blue seal? Eccentric piston seal?
Do you remember the OEM seal being blue?
If you're talking about the eccentric piston seal, I guess not.
I think that you've been doing these longer than I..... (24 years for me).
First gen piston seal was black, second gen brown, recent gen green and double lip, and directional!
Thusly me calling them "blue seal"
Ah!
