Read the quote I wrote 4 more times.....   Its pretty step by step...

To clarify the sockets... NOT IN THE CIRLE... on the circle..     
See picture..








chris-mets:
Ohhhh hahah thanks...about heating the socket....i put in for an hour at 500f and do i turn it off after an hour and wait like 20 mins for it to cool down cause how would i pick that thing up without burning my hand off??? and do I just get the socket and place it on the bearings and wait a minute on each bearing?

Channel locks, tongs., vice grips.... a dumb friend.... etc..    the purpose of the HOT socket, is to be HOT.. and transfer the heat to the bearing race..

4 min per socket swap (read directions again, its there)

chris-mets:
Ok I put the crankshaft in the freezer...tomorrow around 3 pm I will cook the socket at 500f for an hour than take it out with a vice grip...then I take the crankshaft out and hold the socket on the 2 bearings 4 minutes each...then I place the crank in the tranny side...then I put the yamalube on the other side and place it on and screw some screws on tight...correcto?

Friar-Tuck:
  :-D You could have put the crank in a plastic bag (shopping bag etc) but thats the Idea.   MoRads thread also said to lay out your case bolts in advance,  and put them in half torque first have a beer while things are equalizing, and then final torque.

  I think it would be easier if you took the long post and broke it down to one step at a time on 3x5 index cards.

  Thank you for taking the time to post all the information and set up the photo's.
         You will be glad you did when it comes time to write the book.    That chapter would be done! 8-)   
                   Unless you told him how to use the pick-up truck press method.. :lol:
