Changing a brass in a solid bearing is rather more complex, since you have to jack up the truck frame, then maneuver the old brass (bearing) out, possibly install a new gasket at the back of the journal box, maneuver the new bearing into place, lower the truck frame, and then pack and lubricate the journal box.
Very close. but there is a wedge above the brass/babbate bearing that needs to be removed before the bearing can be removed.
