I have noticed on a 74/75 wide gauge bombardier that has a large bearing for the spindle (the one the bogie spring bolts on to) on the 74/75 bombers. As for a 78 era bomber, it has a smaller size bearing. Is there any benefits to either or? They seem like the same size bearing as the inner wheel bearing I may be wrong but I think it would be a good time to start up a "Bearings" topic in the drivetrain section. Any comments regarding bearings can be put in this topic
