Front wheel seal: Spring facing in or out?

Back to my seal installatin on the front wheel.

When I removed the old seal, it had the spring facing out. I tried
to replace it the same way with a new seal but could not get it in
all the way. I ended up ruining the seal! I decided it was in
wrong so I put in another with the spring to the forging which
means the smooth edge of the seal faces out. It went in fine this
way and it appears that the tapered rubber on the seal will match
the spindle.

After further discussion with another Amphi owner, I am not sure
which is correct.:
Smooth size of seal facing out or spring side of seal facing out?

I don't find a clear drawing anywhere to clariy. Does anyone
know?

Thanks,

David C,



I called Hugh Gordon and he said the same as you: <font COLOR="#000080">spring facing out</font>. I had the old price list saved on my computer and the seals were almost $26.95 each so I origionally went elsewhere. Now they are <font SIZE="4">$12.95 so I ordered two. His are double lip. I will return the other 3 I just ordered this morning from EB Atmus. Hugh says to get the grease with Moly, Lithiam & Graffite.



Still in dry dock!

Captain Terry,

The original correct seal orientation was to have the spring side out
but I notice that with the double lip seal that's currently being sold
the second seal is right at the closed side edge of the seal and I
don't think it will touch the hub if the seal is installed spring side
out. By installing the seal with the spring side in you get the use
of the second seal, now running right at the outer edge, and you also
move the location of the original sealing surface to a different point
on the hub. One of my hubs was also a bit worn at the original
running area so I installed the new replacment seal with the spring
side in to get two sealing surfaces on two unused portions of the hub.
It's been that way for a few months now and so far, so good.

<blockquote>Captain Terry,

Thanks John,



I will wait for Gordons and see what they look like and also the additional ones from EB Atmus and then experiment.



Thanks for your input!

The original correct seal orientation was to have the spring side out

but I notice that with the double lip seal that's currently being sold

the second seal is right at the closed side edge of the seal and I

don't think it will touch the hub if the seal is installed spring side

out. By installing the seal with the spring side in you get the use

of the second seal, now running right at the outer edge, and you also

move the location of the original sealing surface to a different point

on the hub. One of my hubs was also a bit worn at the original

running area so I installed the new replacment seal with the spring

side in to get two sealing surfaces on two unused portions of the hub.

It's been that way for a few months now and so far, so good.
