The main fault I find in the Bentley write up is on 770-2 (Step6, Fig.3), where I have never needed that tool as shown. The inner bearing always comes right off with the hub for me. I think the rest of it is pretty good, and that it will become clearer as you do the job.

I hand-pack the bearings, putting a gob of grease on the heel of one hand, and forcing the bearing down into the edge of the gob with the other hand (sort of a wiping motion), until the fresh grease starts to come out of the upper side. Then rotate the bearing slightly to a new position and repeat, working your way around. Yes -- it's messy. But it works for me.

The best way to clean them is to use a degreasing machine or parts cleaner. I myself only use gasoline to wash thm out, it works very well. To test them just give them a spin. After you clean them spin the bearing on your fingers and feel for any roughness or bumps as they turn. The bumps indicate a flat spot on one of the roller bearings. If they spin freely and smoothly you should be ok. As for packing there are many methods. i have sen people take a glob of greese and put it in their hand and then sort of slap the bearing into the greese. I myself use a bearing packer available from any parts store for about 5 dollars. You put the bearing in the device and then use a greese gun to apply the grease. Remember that the object is to push greese from side of the bearing to the other passing through the rollers inside the housing. The bearing will tight and hard to spin when done correctly. As for the torque part it is covered in every manual I have ever seen. Tighten the bearing as you are turning the rotor until it is fairly tight and the rotor is hard to turn, back off one turn then retighten it by hand until it stops. Remember you are using your hands to tighten it and not a wrench. if you must use a wrench then tighten it until it just starts to have some resistance. your object is to keep the bearing from having any side to side or top to bottom play, NOT to tighten the bearing as you would a bolt or nut. Hope it helps..
