From going through the process in building motors I notice some parts are replaced and have a new part #. Such as the new B series LMA have been replaced by a new type and with the part number 14820-PCB-305. And a new one I found out, the GSR right cover assembly which original number is 11300-PR3-000, has been replaced by the new part number 11300-PR4-A00. Is there a thread already made for this kind of information?
