Replacing REAR HUB SEALS - RA-101-21
The rest of the reassembly job is, as the book says, the reverse of disassembly, and of course you will be cleaning the brake parts thoroughly in the process. Just a few more pointers to help you along. Be sure that the seal is fully seated to the bottom of the hole, and that the bearing is also fully seated in the housing. Torque specification for the big octagonal hub bearing retaining nut is 140 lb-ft (19.34 kg-m). [Amend that to 140 lb-ft MINIMUM, and see torque notes on next page] With a big torque wrench and the proper socket it's a cinch. With the big socket and a t-bar to turn it, you'd best have arms like Popeye the Sailor Man. Without those kinds of tools it's a lost cause, and you'll never get it tight enough.
Install the bearing spacer ring for the disk wheel car only. Install a new o-ring in the hub, and a new paper gasket, and align all three of the screw holes (only one threaded hole in the wire wheel bearing hub) between the axle flange and the hub when installing the half shaft. Install one flat head screw to hold the halfshaft (or splined hub) flange to the bearing hub. Tighten that screw as well as you can to pull the gasketed joint up tight before installing the brake drum.
