Do one side at a time, Jack the front wheel off the ground and remove. Remove the Brake Caliper and Rotor. Remove the large center nut in the Hub. Now remove the two bolts holding the lower part of the strut to the A-Arm and separate. You should be able to pull the hub down far enough to get the end of the axle out with some wiggling and possibly swearing, it not you can remove the lower A-Arm and just pull it off. PLACE A DRIP PAN UNDER THE SPOT WHERE THE AXLE GOES INTO THE TRANSMISSION BEFORE PULLING THE AXLE! Replace the axle to trany input seal and reverse order my instructions. Repeat for other side. This is a good time to replace Brake Pads and Rotors as well.
If all you want to do it replace your fork seals, if you can find a way to jack the bike high enough, you don't have the fork tubes our ot the triple trees. Work with on fork tube at a time. Raise the bike up off the ground and take the front wheel and fender off. Brake caliper off it's tube. Now raise the bike up to where you've got about a foot of clearance below the lowest point of the slider. Look underneath the slider where the axle goes through and you'll see an 8mm bolt. Take this bolt out and your lower slider will come off. The fork oil will start to drain as soon as you take the bolt loose as well. Leave a pan under the upper fork while you work on the lower to catch the dripping oil. Replace the fork seal and reassemble that tube. Then, do the next one. Now, refill the tube with the correct amount of the correct oil from the top by removing the top cap nut. Pour in the correct amount of oil for a "wet" refill. The thicker the viscosity of the oil, the firmer the front fork action. I think they came with H-D type E which seems to be a bit softer action than 30 weight fork oil. Make sure you use fork oil. Regular engine oil or transmission oil should not be used and it will foam if you're riding down a rough road and your forks will collapse and not work until the oil settles again. Not a pleasant feeling. It's really doubtful if you'll get anywhere that is that rough with your Harley.
The headline of your post seems to have it correct, you have a fork seal leaking. To replace the seal, you must remove the fork slider, the lower part of the fork tube to replace the seal and then refill the fork with the proper amount of the proper oil. Here's how you do it on a conventional front fork. This is not for an "inverted fork" where the top part is larger than the bottom.
Remove the front wheel, the caliper if it's on this side or you decide to do both sides. Loosen the pinch bolt on the back side of the lower triple tree. Remove the large nut on the top side of the upper triple tree. Caution: there is a large spring under the nut. Usually, if the bike is completely off the ground, the sping is almost fully extended but it will still have some pressure on it. Remove the spring and work the fork tube out of the triple trees. Turn the thing upside down and pour the oil out of it. Notice in the very bottom of the lower slider where the axle goes through, there is an 8mm hex head bolt. Using a brand new hex key, remove this bolt. A hex key socket on an air wrench helps to remove this bolt. It takes a "piloted key" but you can get it out with a regular one as long as it new and not rounded. Once the bolt is out, pull the top tube out of the lower tube. You'll see the oil seal in the top of the lower slider. Pull the seal out and replace it with a new one. Reassemble the entire assembly and install back into the triple trees. Add the proper amount of the proper weight oil. This is what is commonly called a "dry" fill since you took everything off and wiped it down. Then insert the spring tapered end first and put the large nut back on the top.
Then do the other side if you wish. Only do one side at the time. The remaining tube that is put together helps hold the tube you're working on extended.
Don't worry about a little oil on the shock, the seal has gone bad, common problem, usually from a hit on the side pushing it out of round. You need to take them apart, dump the oil in a tray or pan, layout the pieces in order on newspaper or in a big tray, replace the seal, put it all back and pour in a pre-measured amount of fork oil. Be careful pushing the springs back in, Hope this helps.
i have a 2004 hyundai accent , dripping oil from the front side ,nearest the radiator, its. not hte head gaskets. it's farther down on t he engine but i cant see anything but the drips . the manifold comes of the engine right there. from the front side looking down it's dripping on the engine mount , or some mount that you can see.
what part around there would cause this leak?
check first to see if the leaking fork has any rust pitting on the chrome,if it has and its a very small blemish then fettle it off first,and just replace the leaking seal,as the saying goes..if it aint broke dont fix it,if the seals had been in the forks for years and the bike not used then consider replacing both..
hello and welcome
with the cold weather these seals are very apt to show leakage especially with age. the rubber seals become harder in material and will leak. the cold just helps with that and is more apt to do so then.
there is no good product that will work on these and fix them well enough to where they wont leak again soon. the best fix is the get the seals replaced. as the temps warm the leaking may stop. but as another cold front comes the seals will leak again. this can possibley throw off the balance of fluid in the forks and can be damageing. so again definately reccomend getting the seals changed at the earliest conveinience. thank you.
If you get the sevice manual or contact a dealer to get the correct oil amount for your bike, they need to know the model and year, you have to have the forks off the bike. take the fork caps off, take the springs out compress the upper fork tube all the way and add the specified oil. if they also give you the measured amount from the top that's the best way to get both fork oil levels exact. there is a special tool that you set the oil level in millimeters and it sucks out the oil to the right level, but before you do that step after adding the oil always pull and push on the cartage rod several times to remove air from the cartage tube. you will hear the air coming out and you will feel the changes in the cartage rod as the cartage tube fills up with oil and the air is removed.
something i'm confussed on though is if you replaced a seal you would have had to brake down the fork to replace it. you would have poored the oil into a container, cleaned all the internal parts,and used a fork seal driver to install the new seal. part of your question asks where do i put the oil in? thats in the open end of the fork after you have taken off the fork cap. It sounds to me like you only replaced the dust seal on one fork. that is not going to fix your leaking fork. you need to replace the oil seal thats pressed inside of the top fork tube.
