Main gear one way bearing ?

Dose anyone no what size this bearing is, this is the second one that has gone and I would like to replace it with some thing that works, The ones from century are a bit crap

That is the bearing specs.

Getting that one will not be a guaranteed fix. There are a few things you need to do to make sure your one-way will not fail.

1. Make sure you clean it out with carb cleaner followed up by compressed air. Make sure you insert the sleeve in the bearing half way so you do not blow out the needles. When you are done, lube the bearing with a light oil.

2. Installed another frame cross-over brace between the canopy supports. This stiffens up the frame and helps keep it from twisting which upsets the one-way bearings.

3. Get some 3mm washers to use as shims on the clutch hub assy. The hex spacers that are in the hub are a little too short. This is causing some twisting as well if you do not tighten it down properly. By installing these washers, it takes the guess work out of it. They will be small enough to fit inside the hole with the hex spacers. Just CA them in place.

If you do these things, your one-way will be much happier. I have been running stock one-ways for awhile now and have not had any of them fail yet. I ran them for quite awhile without doing the above. They would lock up here and there, but I made sure to free them up after each flight. Now with these things done, I have not had one lock up in quite awhile.
