Anyone else measure a replacement, curious if I recieved a new version or just differences in production. It measured 12.02mm both my pro and sport measured 11.97~.98. Still waiting on a new one way bearing, both of my failed ones were Germany stamped. I have an Align replacement coming to see what shows up and also some from RCbearings.com. We will see.

True 12.000 mm and 11.95 mm if I apply slight pressure to the dial. The 12.00 mm is the new sleeve part # 60139T

I just received my replacement on way and sleeve. I also read the OD on the sleeve at 12.02mm and like you say if you force it a little it goes to 12.00mm. Also , the one way appears to be the same as before. Says HF1216 - Germany. So maybe just the sleeve changed.

OK on 1216. The other markings as well as the needles and the cage do look like my original oneway, but who knows. We'll see how the new one works tomorrow.

My boca one now has about 1.5 gallons without an issue and still smoother than the align.

the HF part means "drawn cup roller clutch"
12 is the ID
16 is the length

everything you ever wanted to know about roller clutches and sprages

To bad there is not a sprage in the 1216 size

If I remember correctly, the bearing itself was not the issue, just that the sleeve diameter was too small, the only change was going to be to the sleeve, which it looks like it has...

But Honey, I can't live with just stock.....

Also the crush on the bearing (The ID of the bearing housing) will have an effect on the ID of the bearing too.
If the bearing does not have any crush on it then the bearing shaft will have to be a larger OD to make it the correct tolerances.
I would think that they would have the correct crush on them, but a few I have seen only have Loctite on them and are size for size.

I flew with the HN6064 replacement oneway today. Three flights and not a hint of a lockup ! Looking good so far. BTW I cleaned out the new bearing really good and lubed it with TriFlo.
