Fork Seals Will Not Seat - 1978 GL1000

Post by Winger1957 »



I removed my forks and removed the old fork seals, but I cannot get the new fork seals to seat. I have ruined two brand new pairs of seals trying to get them installed, and man this is discouraging. The new seals are just too tight. Even with a rubber mallet I cannot get them down and properly seated. All I am doing is ruining four brand new seals. Is there any information on installing new seals that I am lacking? I live in San Antonio TX and will gladly pay someone to install new seals. This is ridiculous.

OK, I think I see what I did wrong. I installed the seals with the solid rubber side down, and it looks like you installed yours with the solid rubber side up (numbers, short lip). And I don't have a slide hammer, which is probably essential. Where did you get that thing?

Yes that would be your problem. Spring/open side of any oil seal is always toward the oil you are trying to seal.

I didn't use a slide hammer. I cut a piece of white pvc pipe that fit the outside rim of the seal. Then just tapped it in. By the way that wasn't my video. Happened to find it on youtube. Oh, a little lube on the rim of the seal helps.

I used the Motion Pro seal driver when I rebuilt my GL1500 forks:

It is super easy to use, comes apart clamshell-like so you can use it with a fork already installed on the bike, and doesn't require sizing or cutting a PVC tube.

Not for all Goldwings. On the 1500, the oil seal has the spring facing up, along with the markings:

That said, if memory serves, you are correct, in that the spring faces downward on the GL1000 seal.

I stand corrected. I have even replaced the seals on my 1500. I don't remember that at all. Oh well. Getting senile in my old age. Oh well!

Thanks for the replies. I take comfort from the use of PVC, as that seems like a good solution to me. Honestly, this fork seal replacement has been my most difficult task to date, and I bought my '78 GL in pieces, so I have had lots of wrench time. My third set of seals will arrive eventually (DavidSilverSpares) and I can begin the process of destroying them. Short story: the only tool I had that matched the diameter of my oil seals was a c-cell LED Maglite, so I used it in conjunction with my mid-weight rubber mallet to seat my seals. One seated nicely, although (thanks brothers :( ) upside down. But the Maglite still works like NEW. And yes, I beat that flashlight to death yet she still looks and runs like new.

I think that the seals were as difficult to drive into position as they were because 1: I was installing them upside down, and 2: the steel ring inside the seals is most resistant to flex with tney are upside down. So the steel ring has no give in it and therefore is nearly impossible to drive into position. Flipping it over so that the flat of the steel ring can flex a bit should make it easier to hammer into position with my #5 sledge and Maglite.
