all you have to do is replace the rubber ring where in goes into the transmission?
or is it better to replace the whole cable?

 

The o-ring

 

Check out the post made by FDX2003Rider before you change the oring out.

Not unless you "want" to change the cable also............... O-ring and maybe the housing gasket.
If it is going to eat at you in the back of your head, then go through the set it up completely for peace of mind.

 

Do yourself a favor, the new cables from Harley or if you get one from Magnum are coated and have a Teflon inner sleeve for a smoother pull. I did the easy pull conversion on mine, is was offered by harley to upgrade the older bikes to 2006 specs, it's a new lever for the trans cover that has more leverage and new outer clutch spring. I fit the clutch spring on right through the derby cover. I can one finger my clutch now.

 

Are you sure thats where the oil is coming from? I thought the same thing so I pulled the clutch cover, took the clutch cable out, inspected the oring, and it was fine. So i put it all back together, cleaning it real well to be sure this time I could watch it real well and see where it was coming from. Turns out it was where the black cable was spliced into the metal up by the housing. I put a little double sided silicone tape around it and a little bit of electrical tape around that to hold the silicone tape while it cures. I know its farmerified but it will work til this winter and ill just swap out the cable.
Not saying its not you're oring, this just might be something to check too.

 

As you may already know... do not over tighten the cable/trans cover connection.
It's very easy to break the cable threads. Use a little lock tight, a new cable should already have some applied.

 

Every time I had a leak in a clutch cable, it was due to a split in the cable.
I don't know where you are at in trouble shooting results, but you may want to pull the cable off and inspect it closely. Speaking the obvious here, but, worth mentioning.

 

Schu,

I have had the same issue last year (see this thread, images included).

When I had detached clutch cable at the clutch lever I found out that the cable fitting had loosened from the cover. This caused oil sweating out and collecting at the lowest point of the clutch cable.....

Re-tightening the cable fitting probably could have solved the problem but changed the clutch cable anyway(FXDP type +2 inch over stock).

If this doesn't stop the oil sweating out, I'd replace the o-ring. If the cable doesn't show any fray, IMO there's no need to replace it. A few drips of engine oil every 4000 miles makes it run smoothly.

When replacing the clutch cable be careful not to ruin the thread in the cover!

Here's how I did it:

When installed at the cover end, ask a partner to hold the clutch cover and route the clutch cable's lever end along the lower frame tube and work it up towards the handlebars. Once it's positioned right, re-mount the clutch cover using a new gasket.

Loosen/fasten the bolts in this sequence:
