Help! Cant find leak

[01ClassicGlider]

I apparently had both a primary leak and an engine oil leak. I replaced the main shaft seal and still saw oil. Went back in and put the baker bearing and seal in and am seeing oil. I have put that dye in all three but it just doesnt illuminate the best for me. The oil is coming from some where in between the primary and engine. Where would engine oil be coming from there???? The pan looks to be dry what else could it be? Does engine oil come from the shifter shaft oil seal? I would think that would be primary. I have went in to my inner primary twice already and want this to be the absolute last time. Can someone please give me suggestions to look at more closely? I am gonna add more dye to my oil today and maybe take it for another spin. Its wet when I stop under the back of the primary and it will also leak some out while parked. Sometimes a drop or two and sometimes a tablespoon or two. I am just too poor to take it to a shop right now.

shifter shaft seal is whatever you are using in your tranny. If you are using gear oil it will have that stinky smell.. take a flash light and look down at the shifter saft if it is shinny with oil might be your problem.

you have a couple of bolts that go through the primary case to the engine.. you need to make sure that you put some silicon on the pads when you install the primary case..

only took me two to three years to figure this one out..

I got lucky and just happen to have a griime trail when I tore mine down the last time... I do believe that this is mentioned in the service manual..

I was going to replace that but thought we had to pull that shaft but understand now we would not have. wouldnt that be gear oil though and not engine oil? I think I am having engine oil leaking due to its color. The oil is dark like my engine oil. I have 3,600 since the last oil change so its kinda dark. The gear oil isnt that dark. Where would engine oil be coming from in that area is there no spot for it to come from???

yes what ever you are using in your tranny if it is the shifter shaft seal. gear oil stinks very distictive smell.

Avoid getting silicone in the bolt holes. Very important! (Hydroloc)

Well I took a sample of the leak and spread it on a piece of copy paper. Did the same for both engine and tranny. I think it looks more like the tranny. As for the smell I think tranny. More importantly i had to add 10 ounces to my tranny which in turn says hey its me. Anyways the manual was unclear on the black silicone so we put it to both threads and the pads. So should the silicone only go on the locking tabs on each side? When cleaning the old stuff off I wire wheeled it and then sprayed brake cleaner on them. So what exact parts need to get the black RTV and where again?
Thanks

on the primary case (outer pad) and the engine/trans pads.. but not on the threads..

Check the o-ring in the spedo sensor. Drove me crazy for a few weeks thinkin it was the primary!

My guess is it is the shifter shaft. The seals harley uses are very prone to failure. Replace it with a James double lipper.

[01ClassicGlider]

Which is better the metal or the plastic type one? They are both double lipped.
Thanks

Pads? Do you mean the lock in tab washers for the bolts? Each side of that?

Well, if it can go wrong it will go wrong. My spare truck has a bad tire. My main pickup blew the in tank fuel pump and the radiator started leaking. I havent even been able to take it for a ride. Today I am gonna put a couple of hours on it. My tranny was down 10 oz so I am sure that seal is bad. I went yesterday and got a james double lipper. I am sure I will be able to tell when I put it on but which side goes out? Is it the flat side or the concaved side? I am assuming the concave side goes to the inside and the flat side stays out towards the primary? I got a cometic gasket for my main primary. Those sure do feel alot better. the indy says I dont need halomar on it either. feels like a foam covering on it. I already replace the main bearing and seal. I went with the baker setup and cut my race off. Mine was pushed into the pulley and my buddies was pushed out to the primary. They sure can move. I see why harley has left that behind. I know I should replace the seals behind the pulley but I dont have the special tool as I had returned it to the guy who loaned it to me. I have also already replace the jack shaft oil seal. Some night this week all this is going to take place. I only got one of those shifter seals as thats all they had. I hope I dont screw it up. Thanks for all the tips fellas and I will come back and let you know how it all turns out.

Use a small drill and place two holes on opposite sides in existing shift shaft seal,,,use two sheet metal screws in the holes and use pliers to pull old seal.
Put tape around knurled shaft so as not to screw up new seal,,,light grease on new seal and seat it with proper size socket flat side out facing inner primary.

where the primary inner case meets the engine/trans cases..

those spots almost always leak..
