Doing the rear end service and I am having a heck of a time seating the driven flange fully into the final drive.  I read Mello Dude's post about when he was having the problem

http://www.valkyrieforum.com/bbs/index.php/topic,107892.0.html

but I'd really rather not do all the work he did.  I do have the wheel on the axle and the driven flange seats a bit (can't turn the wheel with the bike in gear) but it is a good half inch from being fully seated.  Not sure how I would line it up any better.

One thing of note, I'm using the red eye o ring set.  I vaguely remember having this problem last time i did the rear end service, which I solved by using an OEM o ring rather than the red eye.  The fat gasket was OEM and the others red eye when I took it apart.

Any suggestions are welcome.  Very frustrating.

Had the same issue as the Red Eye set of o'rings are firmer but I finally got them to seat. Grease on all o'ring fit areas helps a lot. New OEM probably work easier due to being softer compound.

Are you talking about getting the Drive Flange into the Rear Wheel of the Final Drive?  You are putting the flange into the wheel first, right?

Yes, I am putting the flange in the wheel.  Haven't gotten to the spacer yet, I know it won't fit until I get the wheel seated in the final drive.  Going to disassemble things and see if I can tell what is causing the issue.

Sam, the redeye o-rings don’t have near as much give to them. I think you will need to use a 2x4 or something as leverage on the wheel.

Yeah I quit using the redeye O-rings in part for that reason. Plus because I got a whole bunch of the regular ones for each time I do rear tire service.  As long as there’s grease in there I’ve never had any problems. The only problem I ever had was the first time I opened it up the previous owner or his mechanic did not grease the splines and that cost me a couple hundred dollars in new parts tickedoff

Finally got things together.  The "elusive" third o ring was being pinched so I replaced it with the previous one.  That solved that problem.  Also, the large, thin o ring was keeping the driven flange from seating completely.  Solved that by covering the flange with a piece of 2x4 and hitting it with a hammer.  The one o ring I thought was a problem (the fat one) was just fine.  I think I'll go back to OEM o rings for next time.

I don’t think you’ll be sorry just using the regular nitrile  o-rings. As long as there’s three good O-rings in there and of course grease, you should be fine and having it seat properly and just feel it go together like it’s supposed to, makes a big difference for peace of mind. I know there have been cases where that elusive third oring or one of them got cut on assembly and you’re thinking the orings are in there keeping moisture out in grease  in and it’s not really happening, which sucks cause you don’t find out until your next teardown (I actually think that’s one of the selling points for the redeye O-rings but oh well

Just to reiterate what others have said.  I've found the RedEye O rings to be a fantastic quality, but a little more sensitive to the installation process... meaning, these seem to more seating a little more challenging.  OEM O rings do very well as long as regular maintenance is done.

I did have the RedeEye 3rd O Ring bind up one time, which allowed some grease to escape.  Luckily I did my maintenance at about 8k and caught this before it created problems.

Just to add a bit more information for someone else running into this issue in the future . . .

I had trouble getting the wheel to slip far enough to the right as well.  I took the wheel back off and tried installing the driven flange by itself just so I could see what was happening.  Without the added weight of the wheel I was able to get the flange to seat.  I then put the flange back into the wheel and hung the wheel on the axle.  I sat on the right side of the bike, put my knee against the differential and grabbed the tire at 2 points 180 degrees apart.  I applied even and increasing pressure with my knee against the diff and it finally slipped into place. 

I used the RedEye o-rings.  I have no idea how hard it might be to use OE o-rings as this is my first time servicing a Valkyrie final drive.  As has been mentioned I won't know if I did or did not pinch the o-ring but I feel pretty good about how it slipped in.
