Any double bearing failures?

How many hours are you getting from the double row bearings?
My riding buddy had his fail yesterday. It was the double on the jackshaft. He was also meticulous about greasing every ride!
I realistically think if you ride a lot (80 hours plus) a season it would be a good idea to replace them every year.

Thanks for that! I've had instant failures on the drive shaft with impacts on rocks, but always got 10 hours out of the single jack shaft bearings.
I hope more people will chime in with how many hours they ran, so we can establish a safe replacement interval.

Wow-10 hrs. I think if I had to change bearing that often I might of quit. We had the last 2 rides cut short due to failure both on single bearing set in their 3rd season. I have my wife's bike with low hrs. on single bearings and my 15 with double. Not seeing comments about the double is encouraging. Looks like I should change hers out.
2much is bad too
u should not grease the bearings every ride, too much grease is a bad thing. (read the timbersled instructions if u dont believe me). roller bearings are meant to have only enough lubricant to lubricate, overfilling them is not great, it reduces efficiency, and blows out the seal faster letting more contaminents in more easily. check this vid out, the first 4 minutes is the most relevant to over greasing. too much grease is like a person running through waist deep water compared to running in 2 inches of water. I grease mine 1 pump every 5 big rides or 1pump every 10 shorter rides. not saying that this is necessarily the best thing to do but I do know that overgreasing can destroy bearings too. ps my doubles I installed last year about this time are still running fine with probly about800 miles but I'm feeling like I should replace them soon, just to be safe.

It is a pretty quick swap, and I was running a 4 stroke that needed oil changes, valve checks and other things at five hours or less, plus suspension arm lube every two hours.
I don't know it's kinda a double edged sword.
Everytime I grease them after the bike thaws water starts dripping out (just a couple drips) and I stop as soon as it quits usually 1to 4 pumps on a pistol style grease gun. I would much rather not have my bike sit for a week with any kind of moisture in it the bearings. Most likely it is just condensation from the bike thawing is my guess. That's just my outlook on the situation.

34 hours on mine and no troubles with a few water crossings in the mix. Did grease after those rides extra good. I have had some bearing classes and the statement "over greasing is bad" is true, but that is usually industrial equipment at high speed these turn relatively slow. I agree push the water out.

I hear you both and agree on the water, I just thought it was a good idea to at least bring up that there is such a thing as too much or excessive greasing.
