front fork question

Post by walker70 »



Hi,would like to know if anyone has a good way of cleaning the seal area on my front forks,I have never seen this kind crud and rust in any forks I have rebuilt,tho it has been a while since I have done this,the last time I replaced the seals on any of my bikes was when I had a 1984 Honda Nighthawk,attached is a photo of my Goldwing fork,my main concern is to not damage the surface where the seal goes and where the c-clip is. :D

Some people use skotch-brite green pads... others use OOOO steel wool..
I always worry about "bits" falling into the item, and my not seeing it or not rinsing the area with enough brake cleaner spray to wash out the "larger" pieces of steel wool, or whatever .

i have cleaned up stains like those on brake caliber pistons with ultra ultra fine sandpaper : 1600 grit .
The fines that fall off the paper are small enough that two or three blasts of brake cleaner will swish them away .

Another question,while trying to get the c-clips off the forks on my parts bike I got one off no problem but the other fork c-clip crumbled where the snap ring pliers go into it,will post a photo of it today,but was wondering if anyone has an idea of how to the rest of the c-clip out.

Hi Walker -70.. ( Is that your age ? or your weight ?? LOL )

The corroded clip might be removable with very strong dental tools ... specifically the "pick" tool... should find those in good quality auto or tool store ..
The c-clip ring is important ... proceed carefully and don't gouge the metal !!

Thanks,would not have thought of dental picks,don't worry tho I am very careful about not gouging stuff like this,one thing I know none of us want is to have those c-clips not seat properly.

If you haven't gotten it out yet you could take the bolt out of your circlip pliers and use one half of it to dig the clip out. Seat it firmly in the hole and pry it in toward the stanchion and then up.

The problem with the clip I'm working on is that the holes where the pliers go is rusted away,thankfully the forks I'm messing with are on my parts bike and not on the bike I ride,the forks on that bike are ready to be put back together,I just want an extra set of forks as a backup which is why I'm tearing these down.

As I recall the clip is fairly wide. Maybe you could drill a small hole in it near the opening to give you something to pry on.

Hi again,I need some advice about this,was getting my forks back together and got in a hurry and picked up the wrong hammer to tap the seal in,was being careful but I nicked the top part of the fork near the seal,curious if it can be buffed out or if I need to take one of the forks off my spare bike,also can I just slide the fork out without having to mess with the air tubes and such,the reason I ask is because I just took the bottom part of the forks on the bike I ride off.

From the look of the picture I don't think that is salvageable. Those are some pretty brutal "nicks" they look pretty deep. Don't know if you know this but you can use a piece of 11/2 pvc pipe cut in half and use that as a seal driver for the forks. Just use a hose clamp or zip tie to hold the halfs together and use that for a seal driver. It works well and prevents what happened here.
Thanks to all who answer and help. It is greatly appreciated!

Yeah,I didn't think I could salvage it,but at least I have the spare goldwing for parts,I already have the forks off that one and ready to use,like I said about the nicks on the other fork I just got in a hurry so oops!!!,and thanks for the tip about pvc for using as a seal driver,also I would like to know if it matters that when I put the air adjust tubes back on the forks does the little hole on the fork need to be lined up with the hole in the adjuster tubes,I did try to circle the small hole on the air adjuster tube but somehow it didn't take it but it's the small hole on the inside of it, here are pictures.

On the air equalizers does anyone know where to get the orings other than a Honda dealer,the one dealer close to me seems to have let all the good help get away and the new folks just ain't cutting it,it also seems they are charging more for parts than they were. :D

I bought my orings from partzilla. It doesn't matter where the hole is. It can go anywhere. Yes the pvc idea is a good one. I got that idea from this site somewhere.

When you're putting in the new seal put a light film of grease on the recess and the seal. Lube the inside surface of the seal with fork oil.

Then slide the new seal down the stanchion and seat it as far as you can with your fingers. Next clean up the old seal and put it on top of the new one and use it to seat the new seal. Sometimes you can firmly seat it with just your fingers but if you can't then make a seal driver or tap it in carefully with a piece of hardwood dowel and a rubber mallet. Either way, the old seal will protect the new one and make it easier to seat the seal squarely. Even though the old seal on the GL1200 forks will end up slightly below the top surface of the leg it will easily pry out so don't worry about it getting stuck in there.

By the way, if the forks were completely compressed in the picture as I assume they were, the nicks appear to be above the seal's range of travel. If that is the case they will not cause any problems other than you would need to knock down any high spots that would interfere with clamping them properly.

Have a question again,in my haynes manual it doesn't say the c-clip has to go in a certain way,just says to install, but in my clymer manual it says there is a sharp side to them and install that side up,I do not see any difference in either side??? :D

They are stamped out with a die and often the top will have a slightly rounded edge. If you can't see enough of a difference between the two sides then don't worry about. Just make sure it is fully seated in the groove.
