Last night while coming home, i hit some pot holes. okay maybe it was like 5 of them in a row. From experience, ive learned to stay on the gas lightly and just ride it out rather than try and brake while in one. On the last one i heard a MASSIVE crunch. I thought to myself, crap i dented my exhaust pipe. Inspection revealed nothing. Thought my wheel was broken, didnt see anything, so i thought i might of just ran over a soda can or something.
So i continued to ride, and i make it to my friends house, the bike feels very unsettled. rear is drifty and front isnt planted. The bike is just downright scary to ride. it feels like someone is trying to force a tank slapper on me. im on the highway at 20mph right before hitting the triboro bridge and pull over. and have a look see. I cant figure out whats wrong on the road and babied her for 40 miles home.
Turns out my brakes were locked up front....... and my bearing race burst open and i loss half of the ball bearings in my front wheel axle.
So, where can i find new bearings? I dont know what else is broken since i dont have much time to inspect till after finals are over.
Heres the pot holes. i pretty much managed to hit all the big ones in a row at 35-40mph. its not that they were deep, but that they werent gradual and once the front wheel hit the wall of the pothole the suspension couldnt take it.

Drive out the old bearings with a flat head screwdriver and a hammer (better a mallet).
Get some all-balls (or any other name brand) bearings on ebay or elsewhere.
Place a socket over the outer race (outer metal ring) and hammer in the new bearings. Make sure the socket is wide enough so that you don't hammer on the inner ring.
Note: Placing the new bearing in the freezer over night and using a heat gun on the wheel can help them slide in.
Oh, and you might want to consider posting this in Tech instead of the general forum.
no need to use bearings with fancy names, either.
you will find a bearing supply company locally.
just take one of your's in and they'll probably have them in stock and at a really low cost.
it's not like Ducati is making their own "special go-fast" bearings.
do you guys have the size? i was hoping i could just buy em today and have them by the end of the week so i can just pucn them out and replace it.
just punch one out and take it to the local bearing guy.
he can measure them or read and cross referance a number.
i'll bet you walk out the door in less than 5 minutes with new bearings in hand
gonna have to find the local bearing guy first.
JRK bearings on Cony Island Ave should be able to help you out. Ave K ish I think. The old ones are probably SKF should have the manufacturer and part# on them the race and can be cross referenced. ECS also usually keeps them in stock.

Dude, you've had some serious bad luck lately.
Or just fleaBay (http://www.ebay.com/itm/FRONT-WHEEL-BEARING-KIT-DUCATI-MONSTER-800-2003-04-/130561683565?pt=Motorcycles_Parts_Accessories&vxp=mtr&hash=item1e6615306d) (search ducati monster front bearing).
picked up the allballs direct. also picked up a fork seal kit while i was at it.
Good luck with your exams, He Man. Regards, BC
damn Kui, you have some shitty ass luck.
i'll send you a red envelope next year for good luck, with an shekel inside.

jut the opposite. Kui has great luck. all this $hit happens to his bike and he comes out OK.
who else can ride 50 miles on a bike with half the front wheel bearings missing and frozen brakes (in NYC traffic) and come out unscathed?
who else drops his bike on loose gravel in PA, puts a hole in the case and drives it back to NY without issue?
HEMAN CAN!!

that's a very good point. thanks for the upside.

thanks man. will need it.
the bearings are coming in tomorrow! which is way sooner than i expected, the warehouse is in PA. though im not sure if it comes with the oil seal or not. (the tech manual lists different parts for it. theres only 2 pieces in the kit, thats 2 bearings only)
Question:
the bearing sits on the axle spacer which is free to move this much?
Ducati S2R1000 Axle Spacer (http://www.youtube.com/watch?v=LxnseehG_XQ&list=UUUtFSLab3djaesHdsLopZlQ&index=1&feature=plcp#)
When the bearings aren't make the beast with two backsed like yours...
there is far less movement. ;)

Once you install the new bearings, check to make sure that the spacer is centered and in contact with both inner bearing races to prevent side loading when the axle nut is torqued. If the spacer is too short or has been damaged it could lead to premature bearing failure. I would also review my wheel installation procedure to insure there is no front end play. The sloppy spacer in the video doesn't worry me because it's lacking the inner race and the axle...
The good news is you needed to replace those anyway - mine are grinding my axle down. Yep, they're on the list [clap]
Good luck!
Oh while you're doing those throw some grease on (preferably in) the hoop swingarm heim joints. I'm sure mine are eating themselves; bad shape 5 or so years ago when I last greased them.

Sloppy because there's no inner race is OK. Sloppy because the axle is not there is NOT OK as far as I know. There should be very little (~ 1mm) wiggle area between the spacer and the inner races of the bearings.
As for the wheel installation, with the wheel on the bike with all the bolts tight and the calipers OFF the rotors, the front wheel should be able to do at least 2 - 3 complete rotations. Less than that and there is too much pressure on the bearings' inner races which will lead to premature wear.
alright kit doenst come with an oil seal and it was never an option when ordering. going to install the bearings and go find some seals tomorrow at the local duc shop.

the seal is integral to the bearing.
The SKF type number is usually something like 6xxx-2RS. The S means sealed.
the bearing is sealed, but the manual shows a seperate part for the oil seal, it only exists on one side. The side with the oil seal is also the side that i blew out.
"Repeat the same procedure for
the other bearing, which does not
have an oil seal."
on the parts catalog its "seal ring 0000.64471". $10.99 from ducati omaha, will check ducati soho if they have one within reasonable overpriced range.

that part number means it's not specific to Ducati. If you can find someone taking apart their wheel, I bet you can find it else where for 38¢
this looks like it, going to check NAPA autoparts first since its close by. and then pepboys.

He Man,
First, good luck with your finals, they are over now?
Second, and this isn't helpful for your bearing repair, just a comment from the peanut gallery from a guy who is one of the worst bike maintainers ever. It sure looks to me like those bearings were toast long before you hit the pothole. Maybe it was coincidence or the pothole was kind of the coup d'grace (?)

Is that the left side?
I think the seal is just a dust seal on the spacer...a carryover from the old speedo drive days.
ill check if i can put it together without it.
and yes, finals are now over. thank god because ive never had a semester this tough. today is the first day ive slept ass 5am in forever. consdiering i go to sleep around 2-3 or not even at all!!
Anyway, back on topic, those bearings were defintely on the way out. considering they've been through 30,000 city miles, too many pot holes to count, ridden through 2 hurricanes for over 500 miles in 1 shot each time, left ot bake in the sun, left ot freeze in the cold....etc. ive always greased the axle when i can, but u cant repack sealed bearings so, whatever. it was only a $13 repair.
and it also lead me to find out why my damn bike kept shutting off!!! theres a break in my rear cylinder spark plug wire. i have 2 plugs for the rear (DS) which is why it happens at random and the bike still has power, and stays on while riding just has trouble idling. atleast i hope that is the problem. repalced the wire and last night it idled fine. now off to check if i can throw the wheel on without the oil seal.
called a few places, no good.
going to NAPA right now to check what htey have in stock.

bike runs fine without it, the service manual shows the dust seal to go over the whole bearing, which makes no sense to me since the spacer rests on the inner seal of the bearing. if the dust seal is indeed ontop of the bearing there wouldnt be enoug hspace for the axle, unless im seeing it wrong.
