    MX main bearing tolerances are so tight the unofficial replacement procedure is to chill them in dry ice so they shrink enough to roll them in. By the book says to pull the engine and remove the crank.
    Im not sure how cold it is, never measured it, but when you put oil on the bearings it instantly turns to gel and stops flowing.

    Colder than I care to be.......

    No, cool for stress relief. Assemble at room temp for proper clearance and wear measurements!
