dry clutch problem

Hi was wondering i have evo softail with a BDL open primary and i started to notice a few drops of oil coming from bottom of the clutch basket.My question is there must be an oil seal on the shaft the clutch is on which i assume is coming from the transmission.If so is it a big job to replace?Thx

The push rod for the clutch release comes thru the center of the trans input shaft and that is where the (wet) primary actually vented (thru the trans) Typically a belt drive conversion includes a special adjuster screw that replaces the original screw and "bullet" extension that was between the rod and screw. They also include a hub nut, which has an o-ring on the inside that seals on the updated adjuster.

I have very little belt primary experience, but that much I do know. Hope it's of some help
