That’s why I suggested a heat gun on low or space heater on the crank end. A little heat can help, especially in winter time. But too much heat could risk damage to the rear seal and any RTV in there. You should be safe to get it up to 100 - 120 degrees. The engine runs much warmer than that. If you have a cold garage and the crank is about 50 or 60 degrees it’s just making things tougher for you. I like Eschraider’s comment on trying to get down to .001 interference fit. I’ve struggled with too many transmission and differential bearings with .002” or more interference fit. I’ll hone then out to get that down by half.
