Packing Campag Hub Help

I'm trying to re-pack my 9-11 speed Campagnolo hubs and am having a heck of a time with the lock nuts. Are they reverse threaded or something? Pics attached.

Bikes: '''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!

You insert a 5mm allen key into each axle end and turn them opposite each other to remove the axle end cap (standard right hand threaded). Then loosen the pinch bolt (2.5 mm allen or phillips screwdriver depending on the model) and unthread the cone, also right hand threaded. That gets you to the bearings and hub race.

Thanks. I thought that was the case. I was giving those things hell the other night and couldn't get them to budge.

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

They're set very tight.

IME - they respond best to a sudden sharp torque rather than steady pressure. If you have a friend with an impact wrench, stand the hum on a 5mm hex hey in a vise, and use the impact wrench to pop the end cap loose.

I don't use an impact wrench, but sort of duplicate the effect by standing the hex hey in a vise, and using a long arm key with a sudden sharp effort to snap the apart.

I've had the same issues taking apart cranksets. It seems that Campy uses a vanishing oil that dries to where it has a slightly adhesive effect when they assemble components. It takes that sudden burst to pop parts free, and I often detect a "gunpowder" odor when I do so.
