Pulling my nv4500 to have it rebuilt.. having the flywheel resurfaced at the same time(and pilot bearing replaced), what do ya'll think about doing preventive maintenance on the engine by replacing the rear main seal while I have the flywheel off? No, it's not currently leaking, but the motor has 200k on it.. rest of the motor is strong, just thinking about replacing an aged seal before it has a chance to go bad..
