Bought the FT one way bearing (C30) and it has'nt seen two gallons before slipping so much that it turned the shaft blue. I started off with the new bearing and shaft packed it with "Racers Choice" one way bearing grease. I never heard it slipping, but the heat on the shaft is a tale tale sign that it was slippin,,,,ALOT. It's one thing to spend money for your mistakes and crashes,,but this hurts. Especialy when you don't know how to fix it the next time. Next time I guess I will try Tri-flow,,,,,,

QUICK! ,,,can someone turn the gravity off for just a second,,,,

I used transmission fluid to lube mine when I upgraded & I haven't had any problems since installing them in my Caliber's. Both are running OS37's and each time I do a tear-down/rebuild, I just lube it with the tranny fluid again. I do use Tri-Flo for other bearings though and it works great.

I have the upgraded one also and I also use tranny fluid on mine. I carry the fluid in a syrenge( spelling - diabetic needle ) so that I can squirt it right in the bearing itself. Haven't had a bit of trouble with mine since. Did you upgrade the clutch bell also? The one with the flange on it. They should have been changed together.

Haven't had a problem with the one-way bearing either since I started using ATF fluid. Just make sure you clean the bearing well to remove all the grease before lubricating it.

I do have the metal clutch bell. Will try another oil next time.. But as I said I did not hear or realize the bearing was slipping untill I took it apart for a frame repair. Only then did I see the discoloration on the shaft. Have any of you had yours apart and looked at the shaft since your retro?

Trust me....both of mine are taken apart on a regular basis.....or were for awhile. I seemed to be crashing less now. Never noticed the extreme discoloration you noted though. Are you doing a lot of Idle up full power climb-outs?

I do some but not "alot". I check my mix by how hard it will climb out. I'm always slow to spool it up also. there was even small metal flakes pealed off the shaft,,,,,,,can't understand why I did'nt hear it slipping

I would replace the counter shaft and lube with tranny fluid only.....then take it apart after a gallon or so and see if you have the same discoloration. I suspect it was the grease you chose which allowed it to slip and not a failure of the one-way itself. Good luck and keep us posted on the results.

these one way bearings that we use are the same ones that are used in our automatic transmisions in our cars and with the tranny fluid that is in our transmissions they do not fail. Forget using any kind of grease in them and just use tranny fluid.

If the shaft was scalleded so will the bearings be. Something tells me that the grease that you used was so slippery that it would not let the rollers get a good grab on the shaft

I don't understand how it was so slippery as to keep it from gripping,,,but not greasy enough to keep it from heating up.... I guess if I understood it I would'nt be having this problem!!! LOL

Since I'm a lil on the cheap side....if I were you, I would clean the one way bearing real good and inspect the rollers for excessive wear. If it looked ok I would replace the shaft and lube the brearing with tranny fluid and give it a go. As long as the rollers look ok and there doesn't appear to be damage to the ramps they ride on...why spend the extra bucks for a new bearing. Now if it were the stock unit we were talking about....that would be a different story.

If the caliber auto hub is anything like the raptor hubs, it's complete crap. With gentle flying, like hevering and such, they can be OK but as soon as you give it some stick, the raptors lockup. This is primarily due to the collar steel being too soft, so the pins get wedged in. Less often, they can slip. It's all down to the loading distribution within the bearing and the hardness of the metal. Ofcourse, it doesn't want to be too hardened as it then becomes brittle and so can fracture.

I don't know if it there is any connection, but I never had a problem with the one-way bearing in my first, made in Japan Caliber. On the other hand, my second, made in China Caliber was a different story. The bearing failures started happening after just a few flights. But since I started using ATF oil I have not had any failures with the stock bearing.

With an OS37, you won't be putting too much power through it. However, tt could just be that the metal in yours is hard enough. I don't thing there is much quality control in the materials used in these torrington bearings.

I agree with eben, the parts might look the same, but the quality is definetely different between a Japan Caliber, and a China Caliber. Shame there ain't some kind of tracking number, etc. that we could determine excatly where and when our Calibers were made.
