I was
motor sailing and the
wind picked up and I turned the
engine off. I went below and smelled some
antifreeze. Checked the
engine and the pulley on the FW
cooling pump had come off, with it the belt and the engine had just over heated and
lost less than a quart of
coolant.
I retrieved the pulley from below the engine, pushed it on and the hit it with a mallet to get it to align with the flywheel pulley. Seemed tight and
pump rotated with no friction. Put the belt on, tensioned it, topped up the
coolant and ran the engine and she ran fine at correct temp. Cooled down very quickly.
My questions are:
Is this a normal way for a pulley to be attached... no set set screw or other means of securing. I suppose if the shaft is tappered a bit and it might be tight enough ...but seems odd.
Should I change the belt?
What caused this... after 24 years and 4200 hrs?
