Ah-ha, I knew someone had to be doing the PM on this item! So it was you!
I was thinking about making a set from a piece of metal strap. Any idea what size these things are?
I'm ordering the tapered bearings this morning and per the comments, I won't need any special tools.

I adjusted mine at about 16,00 and just greased and adjusted them at 34,000.
I used a waterproof grease that is used in bicycle cranksets and headsets, seems to work OK, but it also seems to be "adjustable" grease, that is, after initial adjustment, I had to adjust it a couple more times as it worked in.

No biggy on the slim wrench, you can make one from a piece of strap, or you can grind down a pair of channel locks or a wrench. Or you can use a brake spring plier (that's what I did) to hold the adjusting nut while you tighten the lock nut with a crescent wrench.
