Sure they're 19mm? I just did my Rapide trailer (750kg unbraked) which has Alko stub axles and waterproof bearings. The thread is M16 (24mm socket). Found the smaller 'one shot' Alko hub nut here: AL-KO UNBRAKED ONE SHOT HUB NUT
Not wishing to hi-jack your thread - I have a query for trailer guy
too. I'll take a seat!
My query is that I'm used to castle nuts with split pins. These Alko 'one shot' nuts are new to me. I dismantled the hubs to regrease. Although waterproof bearings are fitted, the grease does get thinner and contaminated with use. Better safe than sorry in my book. Anyway, cut a long story short. Cleaned hub and bearings, regreased with Starbrite bearing grease (which is strange stuff). Everything I've read about these nuts is to torque them when refitting. Is that just for braked hubs? When I removed the original nuts they had been punched on either side of the shoulder to engage with the slotted end of the hub, I'm sure just as a safety precaution. They weren't on super-tight, and that was from new from Ribcraft a couple of years ago. If I over torque the hub nut - surely this will simply over-tighten the bearing and result in over-heating, premature wear, etc.
What's the correct way to fit these please?
