Centerlock disc lock ring won't budge
 
I'm trying to remove the discs from a set of wheels I picked up last month (used) to throw on the winter bike before we get some real snow here. The goal here is to service the hubs since they feel a bit rough. Front/rear are both Shimano and take the Park Fr5.2 tool. Before you ask - I *am* turning counter-clockwise. Well, trying ..... neither of them will break, even with a large portion of my fat *rse weight leaning into the wrench.


What am I fighting here? I presume a thread-locker (rather than grease) on the threads is SOP. What's your favored leverage position for something like this? I'm worried about putting too much trauma on the rims, as I'm forced to work with them standing upright on the ground. Any advice here?

Put the lock ring tool on a bench vise, put the lock ring on the tool, and use the rim to turn it.

I prefer the bench vise method. Put the tool in the vise, insert the wheel (and add a loose skewer if QR) and turn the wheel like you’re making a hard left in a school bus.

If you do have a skewer that you can add, make sure that it is not tight, because as soon as the lock ring starts to turn, the skewer will bind if the lock ring. The skewer is there only to prevent the lock ring from slipping off of the tool.
