Good quality tapered roller bearings should outlast the bike with proper preload and lube. Unless one failed I wouldn't replace it.
Tapered roller bearings are used in automotive applications because they handle side loads much better. Yes, ball bearings are easy, but they don't hold up as well. Roller bearings are over-kill on a motorcycle, but can outlast the bike easily. All of my airheads have tapered rollers including the swing arm and steering. As I recall, the LM4 steering head uses tapered rollers, but earlier bikes like the 850T used ball bearings. Ball bearings will do fine in a motorcycle, but if it's got a sidecar mounted you want rollers.
Well guys and gals, we have a winner of what happened to cut short my road trip.<Turns out All Balls is made in China, which while I’m not anti-China I do suspect their metals based on previous experiences.
No chance the inner spacer was left out of the installation? Only time I've seen bearings eaten up like that is under excessive preload (or a load the bearing wasn't designed for).
There is no inner spacer per se on this model Victory. Not even seals on the ends of the bearings ie bearing with 3-4 mm of space with a seal in the 3-4 mm of space. The bearings came with seals, but the wheel had no seals in place when I removed it and if I installed the seals the outer spacers would not fit. there is an inner sleeve that goes between the bearings the the axle shaft passes thru. It was installed properly. No excessive preload, I made sure to tighten everything to spec exactly. And I wasn’t loaded down that heavy. Maybe 35 pounds of gear all told. Nowhere close to two up weight.
Well, Phil, you have found the cause of the bearing failure. I left a couple of millimeters on the ends of the spacer because I thought it shouldn’t be rubbing against the inner bearing races. So I should have made sure the spacer was snugged up. Of well, mea culpa. However, this just proves what a great resource the people here are!
Well done, Phil, for thinking of that. It hadn't occurred to me the inner spacer could be the culprit. It's obvious now - the clue being the original bearing failing as well. Glad you got to the bottom of it, GG, and can move on. That sure settles the issue for me.
One I liked was called a tomahawk, that consisted of a wooden handle and wooden 'hammer' that held caps (from cap guns. We'd put 3-4 caps in the hammer, then insert the projectile, a small plug with feathers on it, and strike the gound with a healthy swing. The caps exploded, and the feather'd projectile would head for the stars!Bob
It's the same with the old airheads (where I come from) as well - they weren't very well set up from the factory and needed fine tuning. Unless I've got the wheel bearings out, I just check for play or binding. I obviously assumed all was good in that department and didn't even think of it in this case, since it's something I'd have noticed first off. We all know the problem with assumptions, but most of the time they're below the level of consciousness so don't get inspected. Good of you to bring it up.
I had an EV that spat all the balls out of the front on one side, I was worried that I would have to trailer it back but no it ran just fine with only one bearing, I did buy a small can of oil and with a straw put oil in where the balls came out of thinking the two races would be rubbing together.So if you have an EV and the wheel bearing quits, don't panic just take it easy and you will be fine, there was no damage done to the wheel.
Here's another wheel bearing tip/learning. Another one. On my ST2 Ducati commuting to work I noticed the front brake lever free travel kept changing. I pull up at a set of lights and it would be normal and after a few klms and corners it would be coming almost back to the bars. Next stop after a small straigh section, lever normal. had me looking for a brake defect until I checked the front wheel bearings....Both shot. What was happening was the worn wheel bearings were allowing wheel movement which would after a few klms and corners was pushing the pads back into the calipers. A stop at the lights and they were pumped back again and would even stay there for a few klms esp on a straight road but corners and they would push back again. Replaced the front wheel bearings and all fixed. You may ask didn't the steering feel a little vauge with shot front wheel bearings? the answer id yes it did but I didn't realise until they were changed out and I got my brakes back to normal and also the steering was now fantastic. the degradation in the steering was gradual and you tend to compensate and not realise how bad it is until something like this happens. Learnings.So varying front brake lever travel......check the front wheel bearings. Ciao
I guess you guys always have a backup then, I was 200 km from homeI was 100 km from the I5 on Cascades highway, I crept along for a while until I realized nothing was going to happen stopped at the first bike shop I could find.Even with no balls in the bearing it still offers some support.
No Roy not really. If it has lost its ball it ain't supportin anything. The only thing with balls left was you:) big ones to continue riding it:) As I said the support was the brake caliper,pads and disk on the failed side now keeping the failed side up, along with the good side coping with the added leverage from the one bearing wheel. Ciao
There's still the inner race and the outer race between the axel and the wheelI was in a foreign country a long way from home, I would do the same again if I had to.Thats all i'm going to say.
