Hey, just wanted to say thank you for helping me solve this mystery once and for all! I will never be confused again, trying to figure out which way is up.
Great video, first time doing maintenance on my electrical unicycle which has suspension with seals like this, I didn't know about the lips, installed them the wrong way, quickly found out, saw your video and fixed it 👍
By any chance anyone know if ktm/ husky have a 49mm forks? If so, what models? I’m looking for those red or white rubber guide that moves up and down that shows you compression location
Is this logic applicable to a right side up conventional fork as well? I would assume so, but my seals don’t look exactly like yours unfortunately. Thank you for the explanation!
Question: My friend’s Sherco KYB forks came with a 2 part dust seal. An outer normal looking one and then a small ring that was in that. We’re putting new SKF dual compound seals in, should be reuse that inner dust seal ring?
@@highlandcycles Ok, it turns it goes in the new dust seal and it fit correctly. Apparently its official name is split ring wiper. It drops inside the inner groove of the dust seal. So from bottom up it’s dust seal - split ring wiper - metal spring retainer - oil seal -- all the other stuff. 😀🇺🇸👍
Awesome! Silly question: if I'm doing a fork service but the seals aren't leaking, I should replace them anyways? Or would you reuse them? I'm guessing I should tear the forks down all the way to clean the bushings and valves and such too? Thanks.
Yeah. This video didn’t turn out like I wanted. I am not good at explaining this. To me it’s so blatantly obvious how they go. When my kids were 3 they understood
Maybe that explanation will end the talk about tieing down a bike while hauling will blow the seals. Those are the same style of seal used in hydraulic cylinders at 3000psi on heavy equipment and they don't leak until wornout.
Sorry for my appeal - seal lips may be asymetric (saw-tooth), as you explained or not. This is not the most important feature or reason. The seal, if you look forms an oil pocket (cross-section is an U-shape). This lets the oil press on the lips. In other words the pressure of the oil assists the seal-force. This is the real key for tightness in operation. The assist goes up with rising oil pressure - exactly, when needed. It is also the reason for older seals drawing air. The opposite direction, seal force is reduced when outside pressure is bigger than inside. Please dont bleed your forks when you sit on the bike or fork is otherwise not extended. You just suck in air at next extension, maybe acompanied by dirt.
This did NOT do it! A recommendation: if you're gonna explain somehting like this, then show a fork tube with lowers on it so that viewers actually understand what you and others truly mean when you say UP or FACING UP. Just put a dang tube attached its lower fork cover on your bench and that truly will show what is meant by UP, etc. Thanks
35 years of owning and working on my bikes. Still have to check 😂cheers 👍
Yes!! Thank you. Perfect explanation. Everyone always says the spring goes down but the seals have TWO springs! Great drawing too.
Glad it was helpful!

Glad it helped
Thanks bro! That was perfect.
First time I ever did one.... yep upside down. Would have been helpful! Also, the the right tools folks!
Good stuff thanks Morgan now I know🤘
Can't wait for the 6500 video
Great topic. I've had dealerships screw that up.
Thank you.
Gracias por ser tan honrado y explicar como vam los retenes un saludo crak mucha suerte 🍀🍀🍀🍀🍀
On any seal the spring on the seal lip faces the fluid. Que?
Channeling AvE, FOUCUS!
Hehehe. Yep
How to face if you want to allow excess grease out while keeping out contaminants on a shaft seal...
To purge out old grease?
You have to do it the same way or oil will come out

Is it the same for conventional forks? Good info. Ride safe my 2 wheel friends.
The lips always point towards the oil

Yes
That's one weird looking C-Ring

I think that’s a spacer for the circlip so maybe. I’d put the seal in and see if the seal is right at the groove. If there is a gap, I’d put it in.

If you are servicing forks, just replace. Not worth maybe having to do them again
@@highlandcycles Also, pretty likely to mess them up getting them loose.
@@Danman1972 yep
@@highlandcycles Glad I already bought them. Thanks!
Up or down is that for upside-down forks or old style, no clearer on which way they go
Yeah. This video didn’t turn out like I wanted. I am not good at explaining this. To me it’s so blatantly obvious how they go. When my kids were 3 they understood

Yep. I have no idea why people think tying a bike down will “blow” a seal
@@highlandcycles it might “sack” the springs to some degree, if compressed for a n extended period of time.
@@gungadingo yes. That is the biggest worry. But even a couple days won’t hurt. But people who store them like that can hurt the springs

I know but the shape is the easiest way for people to tell which way they go in.
The way you explain the oil seal is a little convoluted, it would of helped seeing the last step with both seals and clip all lined up
Sorry about that
Say bruh, whose pleasure are those gloves ribbed for?
😂🤣
FOCUS !!! 😂 great video brother
Well that was about as incomplete as you can get.
Huh, just a vid to show how they go on, not how to do the job

Sorry. Guess I thought the audience was smarter.
Now I’m more confused , not all forks go the same way. It would be way more easier to say witch side goes toward the fluid/ oil.
Yep. @@aorakiboydog
