Hi Jim,
There is a problem that you have that they may fix for you on their dime. You will need to have the inner primary case, transmission cover and possibly the transmission rebuilt. There is a known problem that the MOCO knows about. I really don't think that it is appropriate to discuss it here, I posted my experience here and it was taken out of context and my dealer had to deal with a screaming mainiack that had a different problem.
PM me with your phone number and I will dig up the paper work and history and answer as many of your concerns as possible.
Best Wishes,

I went to the dealer today where i had purchased my bike and also had the previous primary bearing replaced. The Girl that works at the service dept which had helped me in the past with another issue on my bike was extremely helpfull once again. She had the tech that did the first bearing replacement come over and listen to my bike to verify it sounded like it's going out again and she then called up Harley to see what they can do. The parts have been ordered and will be in next week. They will replace my inner primary case, primary bearing and bushing again and also remove my trans and put all new bearings inside and put it in the newer '07+ cases all FREE OF CHARGE.
I am so happy about this, Harley stands behind thier stuff and also i'm do for an oil change so the primary and trans will be done for free, all i have to do is the engine oil and i have a half quart left from last time so i only need to buy 2 quarts and a filter. Hell yeah.

the bearing is the result of the case mis-allignment, so it's not a problem. And the purpose of the bearing and the bushing is so the inner primary case can be taken off easily to change the belt. I dont see how they could press the bearing onto the shaft and into the case.

I have a 2006 Super Glide that was built FEB -2006, my inner Primary bearing failed at 14,500 miles and it was replaced for free about 3 weeks before my warranty was up. now a year later with 18,500 it's making noise again just like it did before. I spoke to the dealer which is 40 miles away and they said i will have to leave it there because the manufacturer requires them to do tests and check things over. I'm just worried i'm going to take it there and they will tear into it and not cover and try to charge me. I do have the knowledge and means to replace the bearing myself but don't feel i should have to pay for it, and i want the problem thats causing it to fail to be corrected. I think it's BS that i'll be looking forward to changing my primary bearing every oil change as long as i own the bike.
Anybody had it replaced a second time out of warranty???? and have the problem solved????

jim, are the new cases doweled?? (trans case to inner primary)
I've been suspecting this is the cause of the failures for a while now.
I'm real interested in hearing about doweling,
and if it holds up this time.

Mine went at 3900-mi. Sounds just like a car's [bad] throwout bearing, but opposite; on a car, you hear it when you push in the clutch; on the bike, you hear it clearly while idling in neutral, but the noise coasts to a stop when you pull in the clutch lever, starts up again when you let it out. Mine sounded like a metal-wheeled roller skate on a concrete sidewalk. It'll be REAL obvious when/if it happens to ya, Adrian. Haven't heard of any of them turning into catastrophic failures that leave you stranded. Rode mine 80-miles home from when I first noticed my noise...didn't sound any worse after the 80-miles.

The roller bearing that is used in this application is not able to handle any misalignment at all. So it is not the bearing design it has to be the issue with case or shaft misalignment which is why some people are getting multiple failures and many get nothing. I suspect some poor quality manufacturing issue with the case or shaft vendor for the moco which is why you should have both the shaft & case replaced when you do this repair.
I sent the pics of some of these failed bearings to a tramsmission roller bearing engineer that I have known for 25 years and he confirmed the cause is definitely a misalignment issue or an oversized shaft which increases the preload on the bearing. So, if you case is misaligned or your shaft has been manufactured a few thousandths over tolerance your IPB is going to keep failing. Best to replace both.
