I want to say there should have been a round reinforcement plate that sits inside the pulley?
I've had that happen too. Got a ride home and then dug out another one to fix. Had it going in an hour or so. I have gone with the billet pulleys now.Just curious if it’s happened to anyone before. ****ty metal? Belts too tight? Dumb luck? Water pump seems fine. Not loose or anything. View attachment 897071
this story turned movie was written by a comet engineer warning about metal fatigue on the infamous vomit jet. Wait for it at the very end of this really great performance by James Stewart.Metal fatigue happens , but not as catastrophic
, as it was on the empennage of the deHavilland Comet.
A snub nose fan spacer heps.Most of the pulleys I've seen that broke like this were the result of either overtightened belts or running without a fan.
