Forget going the lawyer route. Any lawyer taking on a nickel-dime case like this will ask for fees up front. As will the Engineering Company performing studies proving the part is defective. Joe Average will run out of lawyer/engineering money long before the MOCO does. Suck it up...if the part goes bad, fix it.
 
I think y'all are right about the lawyers, maybe as suggested the NHTSB or whatever they are called might be the way. All who have had this problem should be calling and emailing. I think the MOCO and the dealers know they have us over a barrel and are continuing to insert the shaft.
 
Ok, here is what I learn today from a 30 year Harley engine builder I ran into today in Gettysburg, out here on vacation. Has a nice shop on hwy 30 east of gettysburg. He had a 07 RK on the lift replacing the tranny with exactly the same problem I had in Fla when mine went out. Yep, main shaft bearing failure. These worthless bags of junk at HD put bearings in these tranny with PLACTIC bearing casings made in CHINA. He showed me the replacements for it and it is the same bearing that is failing in all these 6 speeds tranny's, same part number as from the factory. He told me best thing to do was to junk that 6 speed and put a 5 speed in it and my troubles would be over.
Well, with only 2500 miles on this 2010 bag of junk FLHTCU I'm going to run the heck out it till it fails and then I'm going to take the busted gear box to Milwaukee and ask for an explanation. Im only 3 hours from the tranny plant in Milwaukee....I want a dadgum good explanation as to why I paid 25,000 for a peice of junk with Chinese bearings in it. If I don't get the answers I want then I'll see an attorney and see if I can't get my money back. Im ticked off....this junk is already showing signs its gonna go out..... Read the post above I found on another forum. I did as he said and removed the trans inspection cover and WAMO.....metal fragments.....this junk is gonna do the same dadgum thing as the RK did.......ANd another thing about oils and tranny gear oils....this 30 year Harley engine builder swears by AMSOIL 20/50 in the motor and primary and Amsoil 75/110 in the tranny......He told me he has raced harley engines for years on amsoil and not once has ever had scoring on any engine parts. Also stated that he wouldn't put HD oils of any kind in a used lawn mower, said he thought more of the mower than to do that to it..
I asked him then why is it that some bikes will run 30,000 or more miles with the sixspeed trannys and never have an issue with bearing failure. He said its all in how that bearing is pressed in, very easy to distort the PLASTIC bearing casing if not pressed in right.....he didn't seem to think it was an oil issue no matter what oil you use. I wonder now if both my scooters were built on Friday or Monday
 
With all the experience we have here is there not an american bearing made that will replace these bearings? Has anyone looked into this? I know Bake rhad the fix for the A motors but sh!t someone has to make on for the B motor specially if Baker knows it.They are missing out on a cash cow sound lie to me. If there is not a fix for this down the road when i do have to replace the dang things I will start replacing with real american made parts, Baker transmission, S&S motor, Rivera primary and the like. I plan to keep this one till I cannot ride anymore. It is a lot of money but if you can take it on in incriments 3k here 3k there and another 3k for good measure walla an AMERICAN MADE BIKE!

Anyone comes up with bearing replacement please fill me in.
 
Baker uses the same made in Canada F.A.G. 8967 main drive gear bearing in their 7 speed. Still not sure if this is a part quality problem or a design problem by Harley
 
Once again a pic of the inner race of the F.A.G. bearing.
I took pics of the new bearing last night - but they're blurry, and the bearing's in the bike along with the Main Gear, and trans. Went together pretty smoothly. Just waiting on the Baker primary bearing now.
One thing I noticed about the case bore for the bearing, is it wasn't smooth all the way around. Looked like tool chatter from the boring bar. But only on about 1/3 of the bore's circumference. I'm wondering if this is as simple as this problem is? The bore is tilted in relation to it's axis? Or rather the axis of the mainshaft? The bearing inner race (outer bearing track) is worn more on one side then the other (see pics) and seems to support this theory.
