How tight do they need be? I have got them pretty snug yet the oneway bearing seems to be a little more tight then it should be and will not spin freely. Any advice on this and/or tips for a silky smooth oneway bearing would be helpful.


thanks,

They must be tight,otherwise they can loose in flight and that´s no funny,
don´t ask how I know
I haven´t never noticed at tightening them makes one way bearing tight,you must check your bearing, it´s maybe cracked,it brokes in X-Spec/Freya quite often.Augusto´s grease mod helps,read it:

Original bolts are a little short too,I made new ones by shortening from longer bolts,they can be 2-3 mm longer than origin´s,it´s quite easy to check by putting them in place without main axle and check the cap between them.You can use a thru bolt with lock nut too,it is maybe safest way.Bolts must be hard quality, use only 12.9 bolts.And red Lock Tite.I hope this helps

Use it as its supposed to.
No problems if assembled correct from the first time.

For peace of mind... your missing the point. Im not trying to improve the stock set up to make it any stronger, I know its fine the way it is. But to me, one bolt with a lock nut is more secure than two with loctite. I don't have red loctite nor want to deal with it.

Dude, this isn't rocket science, you don't have to use red loctite, you don't have to drill out the mainshaft for a through bolt and nut and you won't give up any piece of mind. I've got many gallons through my Freya and X-Spec and a little blue loctite is all you need plus some reaonable torque on the Cap Screws. Get a T handle wrench and have at it. It won't fail if you do it correctly. I've seen through bolts and nuts come loose too, so there is no guarantee on that one either.

Tighten the screws until they bottom out and then tweak them a little more checking the one way to make sure it is smooth.

I totally agree with you. This is not a failure prone item. Blue loctite is all I use and I don't overtighten the bolts. If the threads show signs of wear I simply cut down a new bolt and use it.

There doesn't appear to be any need to reengineer it right now.

What about the hub one?
I drilled out the x-spec mainshaft to put a through bolt in the hub. Won't do it again. That main shaft is super hard. Just thought it was a worry only holding on with two smallish cap screws each side but I guess I haven't heard of them failing so just being a twit.
cheers

I'll add one thing (I agree w/ everyone in that 'leave it alone' is the
way to go), get extra screws (I think they are M3x8) and when you
have any reason to remove them, replace them, do not re-use
them. You'll find that the thread profile gets worn.
