crank seal help

[nelsoncat]

I am installing the lower seals and need to know if they go lips up, lips down, lips opposed or what? I was told they should oppose each other but the ones I took out were lip down; that seems wrong. HELP PLEASE!!!!!!!!

This was from Talon:
"two seals in the bottom end cap with the flat metal part of the seal facing up toward the crank, both seals stacked one on top of the other"
Ya, I know it seems wrong, but thats the way mine came out too.
:rolleyes:

That’s correct. They are only to keep water out. The crank rings do the other sealing.

[Burke Kilgour]

So thats why they're in that way................... I was kinda wondering.
US1, you da man !

Thats the way they came out, looking like they were backwards for sealing fuel in. But for sealing water out they would be correct. Thankyou all so very very much; now I can finish the powerhead tonight although my 6 year old wants equal time put in on the go-cart I am building for him. Looks to be a late night; now if I can just find the thread on squaring the motor with the transom on Vectors::::::::

Thanks again

You can kill two birds with one stone by installing the Merc on the go-cart. That way it will be ok to work on it tonight if its part of the project.

us1 I like that thinking. Nelson if you have grooves on the SS sleeve you can adjust where the seals ride. You can even put in 3 seals! pack some grease in between when installing.

I agree with Jeff G.

I used 3 on the one I did last week - all facing lips down. Doing that makes the wear spots hit differently too.

It made perfect sence.
