Instuctions on installing bearings/races/seals in KH hub?

yeah, it's pretty simple. I use a brass punch so as not to ding up any vital surfaces.
Use a good quality grease, I do not use moly grease on rolling bearings. I pack the bearings by hand to make absolutely sure the rollers, and cages are fully filled with grease.
I'm sure if you search on this forum, about adjusting the bearings, you'll get plenty of tips on proper adjustment methods.
