Which way does conical fork washer go?

[syscrusher]

That really large conical washer that goes right under the oil seal, is the small ID opening at the top or the bottom?c

[easternrider]

Without going to look, I am pretty sure that the small end is at the top. Someone with better knowledge may say otherwise.

[KIC]

can you post a picture ? If it is the one I am thinking of, that has the"lip" on one side I believe it goes down into the spring. I might be thinking of another part since it's been over a year since I did my front forks.

It's number 2 in this photo. I just haven't seen a photo yet in which it is clear.

My thinking is the cone would point towards seal.

here's an image of damper washers.

See if you can open this document. There are some pictures in it. The one I was talking about is on the 3rd page, #4 in the parts photo. Hope this helps.

The photo I posted to identify which one I'm asking about came from a version of that document. The photos just aren't clear enough.

 

I changed the seal out again and it leaks again. I went over the fork tube pretty carefully looking for nicks and found nothing. When I installed the seal I tried to pressurize it before even using it and it leaked air, but could hold up to 4 or 5psi. I can see the oil being pushed out of the seal if I inflate the forks and the watch it.

 

I examined the seal that I just removed carefully and I can find no nicks or flaws in it. It all seems almost like the seal is just a hair too small to fit the fork properly. I don't like the shape of the seal because it looks like there is going to be too little rubber in contact on it but maybe it deforms and grips tighter that it looks. I'm looking for other reasons for this and the washer under the seal did not want to bottom in the top recess of the fork slider, making me think maybe it was in wrong.

 

A member called 5bikes once posted something about installing two seals that were superglued together and I do know that a GW model has two seals to fix a problem. I was considering removing that conical washer and trying to get two seals under the circlip.

 

Present strategy is that I have Lucas power steering stopleak in there, hoping to swell the seal that is in it.

 

I don't really know what to do here - HELP!

Are you using aftermarket seals ? I tried aftermarket seals and had a lot of trouble. Once I switched to OEM seals they went together and work with no further issues.

[syscrusher]

From Boats.net, supposedly OEM.

[MiCarl]

Are you sure the seals are in the right way?

Double lip down, single up.

 

BTW, I agree with Gary. That washer goes in with the raised edge up toward the seal.

The seal is in right and by consensus the washer is as well. I wonder if I can eliminate the washer and use two seals?

[MiCarl]

Something isn't right. The rest of us just put seals in and ride.

 

Is it leaking around the upper tube, or around the outside of the seal?

[syscrusher]

If I do air it up with CLASS I can see the air pushing oil up onto the upper tube from the rear of the seal.

[syscrusher]

That was a confusing statement based on what you asked.

It is where the seal meets the upper tube, toward the rear.

[MiCarl]

Assuming the upper tube is in good shape you've got a failed seal then. It may have been defective when you got it or got damaged on the install.

 

I wouldn't mess around with modifying it, I'd throw a new seal in.

I've done the new seal route twice already and the one I just removed looks as good as the one I just put in, I'll bet.

So I wonder if anyone will be surprised to know that the service manual shows the same number, 21, for the washer below the seal as well as the one above the seal. That's right, according to Yamaha they are both flat washers, but the parts fiche lists two different numbers for the two, which we know is because they are two different parts. I wonder if that's why some people have been buying aftermarket seals that are too tall?

 

Here is my email to Boats.net concerning this:

 

 

I spoke to Joe in tech support about item 3 being incorrect. I cannot spend my life waiting in a phone queue so I will try this. It would probably be best to make sure that Joe sees this since he has talked to Yamaha about it.

 

The long and short of it is that the person Joe spoke with at Yamaha is wrong. Item 23 in the parts fiche is not conical it has a wave to it and I don't care about it at all. What I am after is part 21 from the diagram on page 6-32 of the service manual and part number 8 on the parts fiche (P/N 26H-23149). It SHOULD BE conical, sits under the seal and is the same OD as the seal. The part I was sent is also la belled part 21 in the service manual but it is part number 21 on the parts fiche (P/N 26H-23146). That may be a part of the mix up, being labeled part 21 in both places on the service manual. These parts have two distinct, although close, part numbers and are very different washers serving different purposes.

 

Can you put me in touch with your contact at Yamaha to get the point across? A local dealer will have no more to work with than these errant documents provided by Yamaha to begin with.

 

To sum up, I was sent a part P/N 26H-23146 in an envelope marked P/N 26H-23149, but what I really want is the real conical seal spacer part P/N 26H-23149 that goes under the oil seal just as it is depicted in the parts fiche. Or you can send me a pre-paid label to send this one back and I will just use the one I have.

 

I'm not sure if you can view this thread, but other owners of this machine know exactly what I am talking about:

I'll ask the same question again when I do mine, give everyone a second chance on the answer.

[Bob K.]

Both seal washers on my '93 are flat. If yours are conical, I'd presume them to be damaged (perhaps from the forks bottoming out?) and therefore unable to properly support the oil seal. The oil seal washer's finished side goes against the top of the oil seal. The upper spring washer's unfinished side goes against the bottom of the oil seal.
