front fork seal replacement

Postby tech1 » Sun Jul 31, 2011 10:36 am



Hello everyone. I just replace my front fork seals yesterday. At first I thought it would be easier to not pull them from the triple tree. I then had the bottom bolt stripped out. I thought i was done. Chisled and chisled but wouldn't come out. So I pulled it out which found out is simple. three clamp bolts and a SMALL wire snap ring. I alread had the seal retainer snap ring out but couldn't get the seal. I had to figure out how to get it out without the bottom bolt letting you pop it out. Not much room to drill and slide hammer. I them put the top cap back in and used my blow gun and used compressed air in the drain hole. it took some work and a little heat on the fork at the seal area and it poped out nice. And NO damage to the sealing surfaces. Took her for a ride afterwards and a beautiful night for a ride and no leaks and with freshly serviced front forks.
I find the more I work on this bike the easier it is to work on. I hope this helps anyone with the same problem
PS My ride is an 86 SEi. Quarter of a centry old and still a smooth fast comfortable ride.

Good work except you still have a stripped bottom retainer bolt. You have just become a member of "That %^#$@ Previous Owner Club" :shock: ;)

Yes that is going to be a winter NON riding season repair. I see the bolt is still avalable new. I'll try to get it out or like you said find a donor on Ebay.

Does anyone know of a sight that shows step by step with photos of seal replacement? I have front wheel of already to replace tire and fork seal on one side leaking bad. Are any special tools required? Just need some info and would like to do myself. Thanks. By the way mine is a 1984 gl1200 Interstate.

I'm also looking for a good step by step guide for fork seals.
I may consider doing the steering head bearings while I'm at it.

I did some research and found that you can make a seal driver tool out of 1.5" pvc pipe. Cut a 4" length being sure to get it straight (square) on ends. Now cut it lengthwise down the center. When you are ready to drive new seal in, place the two pieces around upper fork and put two hose clamps on to hold it together. Now you would simply tap around evenly to seat the seal. This is if you don't take upper forks out of triple trees. The bolts on bottom of lower fork came out fairly easy. I left the caps on upper fork that hold the springs in place then I put a rachet strap around bottom fork and hooked around handle bar. The pressure was enough that the damper rod did not spin in lower fork as I removed bolt. I now have everthing ready and just waiting for parts to arrive. The only thing that worries me now is if I will have trouble getting caps back on that holds springs in place. Some say it's hard to do while others say it's no big deal.
