I took my bike in to have a leak fixed, I thought it was the rear cylinder base gasket, they agreed, so I had them replace both. I got it home and it was still bathing itself in oil... I tipped the bike over on the right side, on a hunch, and found the sprocket is leaking. I'm probably going to call the local HD dealership that did the work and see if I can complain them into giving me the seal and renting me a tool to do the job for free. I don't want THEM to do it if they can't diagnose a leak, sheesh. Aaaanyway, is this job as simple as it looks? Seems like a take it off, put on the new one, and be done with it kind of deal. Part Numbers anyone? BTW, this is my first problem with the bike since the last time I posted about anything. Very much a simple to maintain motorcycle. | ||

Hey, there is supposed to be some kind of cap on the center of the sprocket, isn't there? I was looking through old posts and found this out. Does that cap hold in the oil? Because that is EXACTLY where my leak is. | ||

Are you referring to the 5th gear, output sprocket? The one that has the seal in the center that the final drive is attached to. Do you have any photos, as if that is the problem, you are in for a bit of work. Once again, photos of the problem would help. | ||
| Desertfox |
I was able to loosen and remove my sprocket by hand, bad sign? I'll have to post the picture. It is the seal that prevents oil from leaving the trans case at the output shaft thought. The front "pulley" if you will, on the right side of the bike. | ||
| Desertfox |
 It's leaking from behind the sprocket when I tip the bike over. Seems to me like that bearing shouldn't be poking out like that. | ||

Desertfox: PM me and "i" can provide you with the HELP "INFO" to correct that problem ... If any one else wants this "INFO" the same applies ... IT IS SIMPLE "FIX" !!! The MOST FEARFUL thing that can happen to your BUELL is a HARLEY-DAVDISON technician ... HARLEY-DAVIDSON DEALER technicians, making MECHANICS out BUELL Riders since 1989 ... | ||
| Desertfox |
Another question, is there supposed to be some kind of a spacer between the sprocket and the gear? It fits just inside the oil seal. Pics to come... | ||
| Desertfox |
 I got that bearing back in there too. I tapped it in slowly and evenly. Fortunately, I have experience with that kind of fitment from working on VW's and building a couple engines. What is that thing in my hand though? The side facing the camera slides into the case seal over the output shaft. It seems like it's just a spacer that fits against the internal ball bearing... | ||

DesertFox; That is SPACER PN 33344-94 which goes between the CENTER BALL BEARING RACE of BEARING,ball PN 8996A and SPROCKET,transmission either PN 40205-95(29-tooth)or PN 40288-95(27-tooth) which OIL SEAL PN 12067A rides on to keep oil in the transmission when you lean the bike to the right ... | ||

Fantastic, thank you Buellistic. Looks like I'll be leak free in no time. I'll just "persuade" the harley guys to hand over a seal or two for free, since they couldn't diagnose the leak properly the first time. Nearly lost my output shaft bearing too, sheesh. | ||

DesertFox: They do not teach these "technicians" the after effects of running your DRIVE BELT and/or PRIMARY CHAIN "TOOOooo TIGHT" !!! Did "i" send you the DRIVE BELT and PRIMARY CHAIN ADJUSTING Class 101's ??? | ||
| Desertfox |
Yes you did, and I have had mine "scary loose" since I did my first service on it about a year ago. At that time, both the chain and the belt were too tight though. They've been pleasantly loose ever since. | ||

Hate to say it. but if you were able to "tap" that bearing back in your going to have this problem again... this happened to me. what has happened here is your bearing has walked off your main shaft 5th gear. this happens from wheeling and hard acceleration. 5th gear mainshaft needs to come out and replace those bearings. This will happen again i guarantee it. just a matter of time. | ||
| Desertfox |
I'll keep a very close eye on it Serialk. Keep in mind, "tap" refers to the level of care taken, not the actual amount of force applied...  | ||
| Eshardball |
I had the same problem. I took a punch and sharpened it to a point and flame hardened it to god only knows what. I staked the end of the gear so the bearing wouldn't walk out again. 3 stakes has been all that was needed along with a new end plug. An internal groove and a snap ring would be preferred but I really didn't feel like pulling the trans apart at that point | ||
| Desertfox |
Good plan there, hardball. For now, I'm leaving the belt guard off so I can check it before and after every ride. I'll probably get a punch and do the same soon. Of course, that does make the assembly rather permanent... | ||
| Serialk |
well in case you want to replace here is how i did it with home made tools. 8,000km later and its all still good http://xlforum.net/vbportal/forums/showthread.php? t=766754&page=2 | ||
| Eshardball |
Don't go bonkers with the punch and a touch of a small grinder wheel with a dremel will remove the stakes. Since the bearing is a light press fit, the slight encroachment on the space seems to be adequate to hold it in. | ||
| Buellistic |
Before you re-seat the needle bearing you need to loosen the "TOO TIGHT" PRIMARY CHAIN and DRIVE BELT ... THIS BACKING OUT OF THIS NEEDLE ONLY HAPPENS BECAUSE YOU DO NOT KNOW HOW TO CORRECTLY ADJUST YOU PRIMARY CHAIN AND DRIVE BELT !!! | ||
| Desertfox |
The belt-shined swingarm and nearly full inch of primary chain play disagree with you, Buellistic. I'll open up the inspection cover and double check it though, just to be on the safe side. | ||

Dfox, Maybe your field conditions are different, but 99.9% of the the time, an overtightened drive belt is to blame. The fact that the FSM is wrong certainly creates a mechanical problem that may otherwise not exist. At the time of my bearing discovery, I was running the belt per the FSM. Now that mine is run loose, my staking may just be insurance |
