It was kinda like shoving a wet noodle up a wildcat's ***, but I did it on mine. Lots of pieces have to go in as a loose assembly, but if you take your time and think it through, it can be done. It did take me 2 attempts on the first one before I had enough parts stacked up.

Let me provide my 2 cents for you JohnFlorida and I hope someone out there can help me out with my bearing problem.
My 2 cents : Order the puller that you need to tighten the nut to pull it out instead of the hammer puller. I used a sliding hammer puller style and ended up with what I think is a major problem. By my fault I ended up having a few cam bearing pins fall behind in the crankcase area. My heads and cylinders are off for porting and figured it wasn't that big of a deal but I think I was wrong. I have a 1994 fatboy so no oil plugs and I'm not convinced that the pins would slide down to the middle of the crankcase past the flywheel/crank balancer. Can anybody provide me with a solution to remove those pins? Do I need to split the case ? Maybe just remove the engine from the frame and turning upside down hoping they fall (lol) ? Don't know but is there an expert that can help me out there. Thanks.

I would definitely say pull the motor out and split the case, if it was me. It's really not that hard to do. There is almost no clearance between the flywheel weights and the case, if anything gets in there, your cases could be severely damaged. As long as you have a manual for your bike you should be fine. I split my cases when I rebuilt my bike and it was pretty simple.

The words I did't want to hear but I agree with what you're saying regarding the almost no clearance and damaging the case. Don't have a manual but I think it would be a good investment so I'll look into that. I'm sure I'll find the info in the manual but regarding the puller used, do you remember what you used. By the way, your input is much appreciated. Thanks.

I did not need to change my cam bearing, the good one was already installed, But I'm not a fan of the slide hammer type puller for fragile bearings. A good manual is a must, I could not have done it without one.

Are you sure you got the right size o-rings?

Try pulling down the o-ring and putting on the tube and use the tube to insert it. The possibility exists that you might have pinched the o-ring when inserting it before. If you pull it down take a good look at it to make sure it is still good.

Yes did it that way . Put o ring on tube and pushed to set it. Havent had time to play with it today but I'll look at it tomorrow. If I need to I'll by new orings and start from scratch. The new o rings that I put in are brown not black might not be good quality. Bought them from ronnies harley . Thanks for your help!
