The crank will fall in. And still retain enough heat so the rear bearing race does not stick when drawing the assembly forward into the front carrier.
Thank you for the heads up on the heat. The last time I only heated to 200F and it cooled down so quick it was a bit of a struggle. I will certainly take your advice re the 300F.
Re the slingers rubbing. I am sure you are right re the specified spacers working most of the time.
The last engine I did, I fitted a reproduction front bearing carrier.
To get the crank to fit I actually had to put the bearing carrier in the lathe and take off about .25mm on one face so the crank had clearance. So I err on the side of caution now so I dont have to pull it all apart to fix such aberrations.
