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?
