I wish I'd of seen this earlier. It is just the mating call of the wild ULY.

This has got to be one of the better write-ups I've run across for replacing the output shaft bearing without splitting the cases. Really wish I'd found it before I tore mine completely apart a few years ago.

That was very nicely done. That pulley holder is a lot simpler than the one that I made. A lot of well made special tools, what surprised me was all the neat tools carefully machined then the bearing pullers looked like they were hand ground. They worked, that's what counts. Wish I could have done something so simple but I had to split my cases for a bad tranny. Oh well.

I think it's your tranny output bearing. The reason it doesn't make noise in the lower gears is because it takes more rpm to get it to sing. The bearing is brinelled and it's basically the balls running over potholes. As the rpm increases so does the sound. You notice that it's rear wheel rpm related and not engine rpm related.
We overhauled a centrifuge that had bearings 14" in diameter. The new bearings had been sitting in a cabinet for years with the constant vibration of the surrounding equipment. After the overhaul was over we fired it up. Take that sound from your video and multiply it by 100!! You could not stand to be inside that building from all the noise.

I guess it is my turn! As I got to BITA 7, i was hearing a new noise. Described in another forum accurately a sound like a dirt bike knobby tire being run on pavement flat at speed. It got worse as i rode it around the Spruce Pine area. Made it home without incident. Got it out to do a little ride yesterday and noise after five miles turned me back.

The actual output shaft bearing replacement is not a big deal. Have not ordered parts yet. Looks like a couple of hours and four beers!

the above method is only an option for pre-08 years. 08 and up have a different output bearing. Why oh why couldn't Buell have used a trapdoor/cartridge trans like any thoughtful engineer would have?

Yeah, this is probably our next step.

Yeah, it's bullshit having something that morphs simple transmission problems into write off the bike problems for the less mechanically inclined.

Sorry to hear you've encountered some issues as well Etennuly.

I'm going to tear into this job this weekend if I can. The bearing in the video is an early style. The new style is a much better bearing assembly.

Sorry, which video?


/edit: also, if you are planning on doing this, some pictures and a report documenting your experience would be much much appreciated : D

My dad and I will probably start work somewhere next month when we've created some space to work in in the garage.

/edit2: and eh different bearing types? Is that for pre and post '08 bikes?

My 2008 is starting to make a knobby on the pavement sound sometimes too.
Bald tires don't do that.
It didn't click until just now.

Fug. May have to go diggin' myself.

What size is that monster nut? I don't have anything that comes close.
My cheapo calipers say it's 1 7/8 I have to go get some garbage from HF I guess.

My son verified 1 7/8 inch fits.
He liked the huge wrench so much I had to snap a pic:

I'm just glad he didn't drop it on his foot. I would have had some difficulty explaining that to his mom.

BTW found the socket at tractor supply for about $10.50

Well I finally got some more quality time with the nut.
Fabbed up a pulley locker from some old random lug nut and some chunk of worn out brake pad.
Nut came off without much drama but looks like it left a mark on the pulley.
I'm wondering if I could get the seal off for a peek without damaging it like I have done with the wheel bearings.




I'm not 100% convinced that the bearing is bad since I feel nothing wrong with it unloaded like that. The idler seems good too.

I wonder if it's possible my crappy old worn tires were making the knobbys on pavement thing happen.

I won't know for sure until I see behind the seal.

Any sign of oil coming off of the seal? And is that a spacer that is actually there under seal or a actual part of bearing? Work that a bit and see what comes out. After looking in my 07 manual, that is the bearing that seal rides on. Have folks been able to change that bearing without splitting cases?

"Have folks been able to change that bearing without splitting cases?"

D_adams has posted above a link from the other forum of someone that describes how to do this job without splitting the case. This is the link: http://www.buellxb.com/forum/showthread.php?49513- swapping-output-shaft-5th-gear-bearing&p=548319&vi ewfull=1#post548319}

I didn't see any actual leaks under there. It was completely filthy though.
The above picture is after brake cleaner and scraping was done.
I'm thinking perhaps just buttoning it back up for now.
I'm not seeing anything alarming here.

I would start the bike and get it in fifth gear and bring the rpm up to 3000 or so. Listen for a howl from the bearing. A bearing that is brinneled will not show any play but will sing like crazy. The bearing gets little pot holes and as the rollers or balls run over the pot holes it will make lots of noise.

Good idea so long as it is apart.
I didn't think it would make noises if it was unloaded.

It should still make noise but maybe not as loud. I let a car sit too long and the input bearing on the differential started singing at 45 mph on up. I would let off the gas and ease it back on and it sounded the same whether I had it loaded or not.

I went back and viewed that thread. I was impressed. No beating. Took time to press and pull, whatever needed to be made to do the job.
What supports that 5th gear while bearing is out? Any chance of something getting into a position it should not be in?
Also, what is ruining these bearings? Tootals idea of brinneling, what is going on to create that? Also , is the bearing sitting with oil or is it dry behind that seal? A site in UK I thought, showed a person's idea of a grease zerk to lubricate that bearing with a bit extra lube. Not so sure about that either.

My Ulysses (the one in that makes that awful noise in this video https://youtu.be/slp1LldDbr4 ) has just 22.000 kilometers on the ODO, would love to know what caused that bearing to go so incredibly early.

Beats me why stuff sometimes dies early and sometimes lives forever.
I was introduced to "Bathtub curve" today:
https://en.wikipedia.org/wiki/Bathtub_curve
Several factors combining to form a bathtub shape.

I finally got enough time to start and run my bike this evening.
I ran it to 80 virtual miles per hour and nothing was louder than the stock exhaust.

I'm guessing that either it's my cupped baldy tires or it just needs to get worse to make itself known.

Funny thing, it was pretty quick to get it all back together.

aa


Also took a picture of my totally NASA-grade pulley locker:




Random lugnut+chunk of X1 brake pad+ soft aluminum bracket from old GENRAD digibridge chassis.
I think I buzzed it out in under 6 minutes.

I used a mounting stud for the idler but looking back, others used the swingarm pivot as the anchor.

Well, that's good news.

I don't have access to (or any experience with) welding equipment, so we'll have to devise some other way of removing that pulley.

Hope to get started on it soon so I can provide another update on the project.

Did get my hands on a pair of orange XB wheels yesterday. Which means I finally have an orange front wheel to go with the rear one I installed earlier (because the original wheel's bearing housing was busted).

Pic of the bike with just the rear wheel in orange:




And the new (to me) wheels:



Picked them up for 325 euros, not bad I think. Bearings on the rear wheel are shot though. Discs are okay.

I haven’t tried it, but I read somewhere you can make a good locking tool from a section of a broken belt and a piece of wood. Wrap the piece of belt around the sprocket and screw the ends to the wood. It shouldn’t be too hard to work out something along those lines.

This is the new replacement bearing assembly. Comparing it to the one in the video You can see that the center spacer is now a one piece race for the outer bearing. There are a hell of a lot more balls to support the side load it carries from the super tight belts.

It cost $35.00 or so. Up grade from early '06 production dates

My late '05 production date Uly had the seal leak bad and replaced under warranty at about 7000 miles.
