Fork Seals...Any Good How to's for replacing?

Postby wingsfan98 » Sat Jan 26, 2013 7:36 pm



I have to change my fork seals on the front of my 84 gl1200a and was just wondering if there were any good step by steps out there other than Clymer's? Is there an easy way or is it just a hard job like the book shows.
Any tips would be appreciated as well
and thanks.

I've changed all my seals with the forks left on the bike.Just pull the springs and all the other parts.The tubes will bump off after The "C"clip retainer is removed.
A cut and trimmed PVC coupler fits the fork for a driving tool to seat the new seal.

I am trying to change the front fork seals on 1985 GL1200A with the forks in the bike. Disassembly was quite easy, however, I cannot drive the new seal down so it will seat. I was using the old seal, and driving it against the new seal, but it will not drive it down far enough so I can get the snap ring on.

What can I use to drive these in place?

I used a 1.5" PVC "T" pipe ( I think on size) cut in half lengthwise. May half to sand or file ridge to fit properly. Use a tappet wrench to smack it.

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.

Well, I guess I could have told him to buy a $45 tool & wait a week for it. Or just go to Home Depot pay $5 and get the job done.

Tool was $75 CDN total - shipped - all said - all done to my house.

Now, another question.....I see there is a nick in the left front inner tube. It is not large or deep, but there nonetheless and will likely cause leak by.

I see a repair for that on Youtube using a razor blade and super glue - but - is it more advisable to do that or simply go to ebay and buy a new left fork? Are there any other repair suggestions that have been tried and true?

Great article and great presentation btw.

Glue sounds kinda sketchy. Post a picture or two see how big and where the nick is. Then people can help you better.

Congrats on the new tool.
JMO but that looks a little more than a scratch and where it's situated I'm betting the last owner replaced fork seals and beat it up driving the new ones in with ???? . I would be looking for a different good one . Is it just the one or is the other one beat up to .anyone else have an opinion. just my 2 cents

I would probably work the raised up area down with a smooth mill file (gently), next some 600 grit wet dry paper along with some light oil. Be careful not to go thru the chrome. What you want is to flatten out the damage and get rid of any sharp edges. This will leave you with some small divots that should not harm your new seal. These divots will carry a tiny bit of fork oil with them but that should not be a problem as long as the seal holds up. I have done this on boogered up rotating shafts with good results. Good luck...Rusty

If it were a modern upside down fork I would be more concerned, but I have just steel wooled and oiled the sharp edges and new seals have lasted just fine on my race bike with USD forks. In your case, take of the edge and don't worry.
