rear wheel seals logic

[Marty & Caryl]

After many conversations with a few intelligent individuals we all
know and respect on the correct positioning of the radial oil seals
in reconditioned oscillating arm or rear wheel assembly, which is
found in the Amphicar Maintenance Manual chapter 4, I have seen the
logic of placing the inside seal, closest to the car with lip out and
the outboard seal with flat side out.
The logic here is that (and I'm using someone else's words that I
have learned) when you grease the assembly the grease goes through
the hub to lubricate the bearings and comes out where the axle goes
in and can be wiped away, it's important that this seal is kept wet
so that's why the seal is backwards. The other seal going with lip
in and flat side out will stop grease from filling your brakes, which
would impede stopping as well as gumming up the works and making a
real mess of things.
Thanks to all that helped us on this task.
We will see you in Celina,
Marty in WI

According to Hugh Gordon, you have both seals in backwards. I talked
to him about this matter about a year ago. I have the seals installed
the way he recommended on both of my cars and so far (over a
year)haven't had any problems. Logically, I like the way you have
your seals. When greasing my rear bearings, I use little grease and
cross my fingers. I suppose I should be removing the rear brake drums
and checking but if I had to do that I would probably never grease the
bearings.

Makes sense to me, Marty. I've run both seals flange
out for years to keep the water out and found that I
have to be EXTREMELY careful (and have had to clean
brakes on several occasions) when greasing the hub.

This sounds like the way to go next bearing change.

Enjoy Celina -- it was a blast last year, we're sorry
to miss it this time.
