PTO crankshaft seal direction?

[RKJLOW]

i bought VITOS all in one set for the seals for the banshee Im rebuilding i looked them over and installed but the PTO side of the crank the gear isn't wanting to go in, installed the seal with the ribs and the spring facing out there is no OUTSIDE or otherwise markings on it. there's text on both sides of the seal. In the lower-end walk through post #5 http://bansheehq.com/forums/index.php?showtopic=140912 shows the spring on the outside also. I did get the gear to go on but the spring popped of the seal. any input or help is greatly appreciated. supposed to go riding this weekend

the ribbed side faces in towards your bearing.

this is what im talking about am i boned? if i have to split again can i reuse the seals?

Man I put that in backwards forever. It'll be fine. As always, do a leak down test though.

[RKJLOW]

What about this one

I have heard that they aren't directional from a very reliable source.

But everyone is different. I've also heard clutch steels and fibers are directional. So all depends who you talk to I guess.

PTO is backwards flywheel is good and yes you can re-use, did you apply grease to the seal where it rides the crank?

Run it. I've done the same thing before when I was in a hurry and not paying attention. Once was in the turbo bike and it actually lasted better that way..

Some steels have tapered tabs so they are others are not. Pto is backward. Some flywheel seals have green letters that go one way some have nothing distinguishing them.

its not even backwards! i split the case just out of shear frustration and thats the only way that first seal can go in. damn it i hate second guessing myself

Thats the worst. I did that with an aftermarket tranny bearring once.

You spent time making sure its done right. You should be proud of yourself.

I am except the bolt snapped #9 so back apart she goes I should. Have a race with someone by now

A case bolt snapped? Dam those suck.

if the PTO seal is installed backwards and the other side has a solid rubber ring (and some do) you need to turn it around, those notches are a breather for oiling the bearing, I learned along time ago things are not engineered and custom tooling made because Yamaha wants to waste money, they do things for a reason
