Fork seal replacement

Post by Pappy Wilson » Sun Nov 15, 2009 10:12 am

I'm new to the site and am in the process of buying my first Wing (I ride a Pacific Coast now). The owner says the fork seals need replaced and maybe I'm not looking in the right place. I've checked the other how-to articles and they are great buy I can't seem to find one on this. By the way it is an 81 Interstate. Thanks in advance for you time and help.

I haven't done mine, so I haven't written a how-to article on the procedure. That said, it is covered in the service manual - click on the "Manuals" link at the top of the page.

It's very important to keep the seals clean when replacing them!

I've replaced the seals on my GL1100. It's not that hard of a job, but if you're replacing the seals, I would go ahead and replace the bushings as well (1 sleeve and and 1 bushing on each fork). I bought mine from They have a microfiche there you can use to look up parts for your bike. It's the same microfiche they'll use at the dealer.

The part number for the bushing is 51414-463-003, and the part number for the sleeve is 51415-463-003.

Below is what I posted earlier on this site concerning the fork seal replacement. The link included there will show you pictures of what you will be doing. While you're at it, there are a couple of o-rings on the hose at the top of the forks. I would replace them too. I just found a couple that fit I had lying around and used them. No problems. Again, it's not that difficult if you're familiar with your toolbox! ~~

Shoot, while you're at it, might as well slap some progressive springs in there as well. You won't have to run air in the front shocks anymore, unless you want to, and they'll only set you back about $80 or so shipped to your door.

here' s the info I mentioned earlier:
I didn't document it, but I just replaced the seals and bushings in my forks yesterday. I believe I'm an expert at it now {still snickering after that one} since I've replaced the seals on the right fork 2 times (after installing the first replacement seal upside down) and the seal on the left fork one time, replaced the bushings in both forks, and installed progressive springs. It took me about 3 hours from start to finish. I probably could have finished a little quicker, but had to make a couple runs to the hardware store for tools and pvc pipe.

Here's a link to the instructions I used. ... efault.htm

I lifted my bike with a floor jack, and put a car stand under each engine guard close to the front of the bike. Nice and solid, and you shouldn't have to strap the bike up like his instructions say.

He says you don't have to pull the forks in his instructions, but I think it's easier with the forks off, plus once you have the tire and fender off, the forks come off the bike pretty easy, Loosen 4 bolts (1 on the upper part of the triple tree, 2 on the bottom, and one where the fairing weight mounts to the fork tube). Make sure you put the seal in with the writing on the seal facing the top of the tube. It will leak like a sieve if you put it in upside down. Tap it down easy with pvc pipe. I lubed my seals with ATF to help with the installation.

Good Luck!
