I can’t tell from the Lionel exploded view you posted up, ....does the Lionel worm shaft have flanged bearings?....some Lionel engines do not use a step flanged bearing. All big MTH Premier steam uses the 4X9mm step flanged bearing....even still, some Lionel use a 4X8mm non flanged bearing, and the bearing stops are cast in as part of the gear tower....do not use a non-flanged bearing on a MTH gear tower....you will not like the resulting carnage....😉
