Expert Pro-Tip: When splitting cases and installing your new Wiseco crankshaft assembly, heat the crankcase bearing pockets evenly with a heat gun and freeze the new main bearings overnight prior to installation. They will drop into place without using forced pressure, which prevents misalignment and ensures smooth crank rotation once the cases are torqued back together.
