So I'm planning on doing an inner primary job to correct a leak I'm having. Hard to pin point the exact location bit it looks like the shifter shaft seal area. I'm trying to avoid a huge project like replacing the inner race/trans shaft seal. I was planning on changing the inner primary seals, primary bearing and gaskets. Is that enough or do I really need to consider that trans seal too.
The most confusing part is in the service manual, it says the inner race bearing must be properly positioned on the mainshaft to align with the outer race in the primary ? Wtf does that mean ?
Again not 100% sure I'm going to change the race but just wanted to see if anyone knows what that means . Thanks .
I wouldn't worry about the transmission shaft seal unless it's leaking. I would replace the inner race if you are replacing the bearing. I just use the inner race removal tool as a guide when reinstalling the race. You have to leave enough room to get the tool in there if you ever need to remove it again. I'm sure you can find a video on youtube that will show you the procedure.

I actually have a new gloss black inner primary so I was going to install a new primary bearing into that. You're saying to change the race too ?

And what's the manual talking about it being properly aligned ?
Inner bearing race is pressed on shaft ouboard of drive sprocket. (The bearing and outer race live on the inner primary cover). The inner race will sometimes "walk" towards the transmission causing leaks and sometimes premature wear of the rollers of the bearing) The distance given by the manual (.100" I think it's on yours, mine's an 02, probably the same, if in doubt call a wrench)makes sure 100% of the bearing rollers ride all the available surface of the race. If it has "walked" it's your call to pull it or leave it. If it hasn't walked and surface is free of nicks and galling, you're good to go, ignore the bearing and continue with the rest of your repairs.
You didn't specify bike year or number of miles but I wouldn't worry about inner race part replacement unless see problem when you tear it down and do visual inspection. Inspect compensator & chain tensioner for wear while in there. Check oil leaks at grommet where alternator wires exit primary as this is another problem leak area with age. Shift shaft seal is very common to leak. If leak isn't bad I'd differ this to a winter project myself.

Sorry, it's a 2007 flhr. The motor has been redone from a 96 to 107 last summer. New clutch too.
So the bearing on the primary would show wear if the race has walked toward?

You probably just have a shifter shaft leak and may not have other issues. Hard tellin’ not seein’ until you take it off though. HD sells a primary seal kit now to make it easy (black seal).
