Fork Seals - 1987 GL1200IA

Post by keikel »



What parts in addition to the two (2) 51490-MN8-305 seal sets will I need to replace the fork seals on my 1987 GL1200IA?

Can you show me a link to a good guide for doing this job?

Please check the How-To Articles button above. Here's the direct link:

I always replace the bushings when I do the seals. You're already there and they aren't that expensive. I also only use Honda parts for seals and bushings. Again, not that expensive and the Goldwing is a heavy bike so they do take a beating.

Have you checked the steering stem bearings? Any notch, detent feel, roughness, looseness? Now's the time to do them as well.

If the seals have been leaking, pay attention to the brake pads for contamination or just be thorough and change them.

Ok, since I'm spending your money, change the brake fluid as well.

Thanks for your help Andy.

I'm looking at ~$270 in parts and ~$200 in labor to fix my forks. The total is about half of what the bike is worth (in money, that is). I'd do the labor myself if I wasn't so concerned that I couldn't get the caps back on. I'm starting to wonder if I should go forward ... if only I didn't love this bike so much and could afford another one!

What are the odds that I'll need the following parts?
1.) #8, Stopper Ring 51405-MB-003
2.) #9, Stopper Ring 51405-MB-611
3.) #14, Back-up Ring 51412-MB4-033
4.) #26, Piston Ring 51437-MB4-003

I suppose anything is possible but those are not really wear items. Guide bushing and slide bushing I believe will be needed but I would be surprised by those other items you listed.

Check these guys: https://cyclemax.com/gl1200_maintenance

Brake pads $22 per caliper, Seal set $23 per side, bushings $21.50 per side, fork oil $13.50 per quart, maybe a couple drain bolt copper washers $2 each.

Labor for $200 is not unreasonable But there are posts about home brew seal drivers and spring compressors. Worst case, you can buy a seal driver for $47 and spring tool for $186.
