Yep, all good advice. ^ ^ ^
Can use 2 long scredrivers to pry against the main caps and the crank webs to make the crank go back and forth. Should hear a little clunk, can use a dial indicator on the crank snout if ya got one. Careful not to damage the sides of that bearing ya have in your mitts. Thats the thrust faces, they control crank 'float'. Bend one, and you'll have no movement in the crank, back and forth. Assemble with cam lube (or thick Gear oil, in a pinch. )
Most important..!! Clean, clean and clean. Wash your hands, clean rags, clean oil, close the shed doors, blah, blah, blah.................
