Title: Piled up R/R wheel bearing... damaged cush drive??
Post by: loopsrider on September 06, 2012, 08:13:07 PM
Hey all,

I had my R/R wheel bearing pile up on me at @ 13,000km. Didn't lock up on me or anything but that chirp noise and vibration I felt at 140km/hr kind of haunts me a little... :o

Lucked out and never had the bearing spin in the wheel, but the bearing is toast.

My question is after I got the wheel off I noticed the cush drive has a very small amount of play (approx .010") when the sprocket is pulled away and toward the wheel. There is no torsional movement at all.

Is it normal to have a small amount of side to side movement in the cush drive? Or did my wheel bearing possibly loosen it up. Again... there is absolutely no torsional movement in it at all...

Oh... the bike is a '10 696...

So I would assume some play is normal then...

My next issue is the bearing is chewed up so bad I can't get a part number off of it. The bearings are just SKF bearings but it seems the R/R is different than the L/R...

My dealership is a long ways away so since they are an SKF brand bearing I was hoping to pick some up locally.

Anyone happen to have a wheel off of a 696 and want to post up the numbers on it for me? :) The part# is printed on the integral seal on the bearing.

In a pinch a good bearing house can do it by dimension.

Raux... You are a Ducati magician [beer]

I spent an hour Googling and found nothing...

Do you happen to have that link you used to cross reference the numbers... I'd like to confirm the part number for the R/H bearing.

hang on

which bearing are you talking about
on the wheel left and right side or

I'm new to street wheels and have yet to disassemble mine... you'll have to bear with me :)

The bearing that piled up was on the right side (rotor side). I was mistaking the bearing in the cush drive hub as a wheel bearing. So what I have is two wheel bearings and also one bearing on the cush hub. The two wheel bearings seem to be the same (although I can't completely see the one until I remove the cush hub.

Sound right?

Two wheel bearings, and two cush-drive/carrier bearings.

Wheel and carrier bearings are different.

OK...I had time to take this wheel apart. Painfully simple once I got it apart. Two wheel bearings in the wheel, and two in the cush drive carrier. Fingers on the cush drive slide into the bushings on the wheel. The .010" play I was feeling was the fingers binding on corrosion in the wheel bushings. I now know the fingers slide right out of the bushings.

Jumped the gun a little by posting before I tore into it... just was hoping to get some parts together on Friday so I could fix it up on the weekend...

Guess there's always next weekend... 8)
