Was reading some old posts about adding a zerk and giving the fan hub a little lubrication. On my N14 however it only has one plug instead of two mentioned. The idea was to put a zerk in one and watch the grease move through the other. Should I add a zerk and just give it one shot of grease? Almost 5000 hours, probably no maintenance done to it so far.
