Mark -
I found my notes in my old Haynes, from when I did my 1983 245 FWB's after driving thru a 2-ft of water curb drain area (splashed plumb over the windshield!). The caliper bolts are 19mm and the hub is 15/16" which I think is 22mm.
Things to remember: (1) The heated hub and frozen bearing race system really helps if you don't have a press to install the new inner and outer races. (2) The other post on your first re: seals, right way and wrong way - follow it exactly. (3) Use gobs of grease everywhere. Pack the bearings, fill the hub, coat the races, coat the seal, coat the spindle. Use a high-temperature grease.
The final adjustment from Haynes: Once the washer and nut are in place, hand tighten til steady. Then "Spin the hub in a forward direction while tightening the spindle nut to approximately 20 ft-lbs to seat the bearing."
Loosen the nut 1/4 turn, then hand tighten until the washer can barely be moved with a screwdriver tip. Then install cotter pin, backing off nut if necessary.
Check the play, spin and listen and check again. Make the dust cap 1/2 full of grease before installing. Then re-install caliper and you're off. Remember to pump up brakes B4 driving off. DAMHIK (pronounced dammit).
In looking at Haynes, it does have a good layout on this job, even to showing how to use palm to pack the bearing with grease.
Best Luck, hope this helps.
