Message	I have a functioning 90 Amp Mitsubishi Alternator in my car but it is very dirty due to a leaky power steering pump. I am planning on disassembling the unit, washing the front and rear cover, cleaning the generator, stator, regulator, etc, with CRC-Lectra Motive, and replacing the front and rear bearings. Nissan OEM Alternator Rear Ball Bearing part #23120-51E10 is still available, but the front Bearing #23120-58S11 is discontinued. I did some digging and it seems like it is a Single row deep groove ball bearing with the following dimensions: Inner diameter (mm) 15.00 Outer diameter (mm) 47.00 Height (mm) 14 Does anyone know if these measurements are correct? If these dimensions are right, I know there are bearings available in this size from reputable manufacturers like NSK.
