Hey guys, the last time I took my bike on a long ride my axle nut backed off on me. It was right after I gave the bike a full service which included replacing the rear axle and nut. I torqued the nut in accordance with the S1 manual, but this bike has an XB wheel conversion, if that makes any difference. anywho, im looking to ditch my newer stock axle and go with a castle nut rear axle. Every time I ride now, im constantly wondering in the back of my head if my axle nut is coming loose. Its been bothering me psychologically and i'd really just like to have peace in my mind. is there anything out there? or would I have to make it custom? My other option would be safety wire, if I had to make it custom I think that would be the easiest bet and I could use some heavy .040 stainless wire. (ex-aircraft mechanic) | ||

What about medium duty blue loctite? | ||

Try one of these? http://www.mcmaster.com/#hex-locknuts/=xngd05 Click on 'thin nylon insert locknuts'. | ||

I gave the bike a full service which included replacing the rear axle and nut. How about a lockwasher? The tubers used a pretty hefty lockwasher that provided sufficient tension on the rear axle to keep the axle nut from loosening. Just curious, 1313 | ||

You should be using the XB wheel specs in combination with the S1. The XB wheel has an inner spacer that is sacrificial and needs to be replaced with the bearings and the XB bearings have diffrent Torque specs then the S1. | ||

I'm with Hootowl. I just looked at Fastenal's website and they have thin nylocks. I haven't had a problem with mine but would be something to look into. MM | ||

does anyone know what the thread size is? | ||

nothing against the safety wire idea but with proper torque to the XB wheel, good bearings, good spacer, and the large lock washer there should not be an issue. I think it has to do with the torque specs and the spacer something moved. Just my opinion. | ||

Is there suposed to be a lock washer!? | ||
| S1owner |
Yes You can see it pictured here  | ||

I gotta check my bike when i get home. I only remember regular washers | ||

rear axle is metric threaded I think, but can't remember the number. I can check later on my spare. Can we use Loctite on this axle nut? (I didn't, just the big lock washer.) Seems like the old Hondas had castles with a cotter pin. That seems like the best solution to me. Not tempted to tighten it too much, but still reliably locked in place. | ||

Per the S1 manual on the bolt side there is a normal washer. On the nut side there is a normal washer and a lock washer. No lock tight and 66-73 ft pounds. Now here is the issue in this thread he has XB wheels the specs on XB wheels are not to go over 48-52 ft pounds or you will crush the spacer in the wheel. Once that happens you will get bearing issues and things will move as the spacer strength has been compromised. I strongly suggest contact someone like purpony that has had great success with this conversion to get torque advice. With all that said I Never used lock tight on mine would not hurt but could change how it torques. | ||

Fyi The spacer I am talking about is inside the XB wheel between the bearings part 11  |
