I never even saw the O-ring?

Once I pulled the axel nut I sprayed some WD-40 down the shaft under the rotor hub threads. I think this caused the o-ring to slip along and back instead of staying put once I pushed the rotor back. I musta pushed that thing back and forth on the splines 50 times. Never saw the o-ring.

 

pulled mine apart today. my seals had the #s 50x68x10. must be a little wider than some. the oring had chunks out of it that corisponded with the splines.it was toast. the oring is in a groove in the rotor hub. about 1" inside the hub.everything looked ok. I was exspecting to see the hub full of grease. it was clean. just had grease in the bearing race area.when I do bus hubs at work we fill the hub between the bearings. I wonder why bomb did not put grease in there. a little bit of contamination between the bearings and axle. but clean otherwise. could not find the seals at auto parts houses. napa said they could order for 6.95 a seal. I will check bomb dealers tommorrow. and, man o man was that left hub nut tight. it took a half hour of impact wrench, one broken ratchet and a breaker bar with a long piece of pipe for leverage. slow steady pressure with pry bars got the rotor hub over the ridge. one more thing. regular shop grease? or some special synthetic?

 

I didn't know they changed sizes ? Mine is a 2000

 

About any good synthetic bearing grease should work fine. I would reccomend synthetic because water affects it less. If you don't ride in water, it shouldn't matter. They probably don't fill the hub with grease because of weight. That would be another pound at the end of the swingarm.

i get all my bearings and seals from applied bearing out here in california, let me know what you need and i beilieve they can ship, paid a couple bucks for my seals compared to the 30$ they want from an aftermarket kit//

 

tvi had the seals for 17 for both. I still need the brake rotor hub oring. it would not match up to any in the bosch kit.

 

Thanks for lettin me know about this tread busmechanic, I am going to start on this DS in the back today and it doesnt sound like its going to be any fun.

 

lomax, your welcome.
