What happened? Jumped timing?

Ok guys so check this out... Today I was driving...got on the gas from a stop light...low voltage light came on. So I said "Hmm....dafuq?," went to pull over to the side of the road, and as I hit the gas and hit 2k rpms, I got a humongous backfire and the car fell on it's face, but the motor didn't die, so I was still trying to get over to the side of the road, gave it a little gas again and recieved another backfire. So I shifted into neutral, and the idle started rapidly fluctuating between 500-1500rpms. As I made my way onto the nearby frontage road, the motor died completely. An attempt to restart the engine was made, it was turning over but it just wouldn't fire. So I popped the hood to be greeted with a shredded (but still in one piece) PS belt and the alternator belt had come off the crank pulley (thus the low voltage light).

All the fluids were good, wasn't pissing oil or coolant anywhere, not overheated. My uncle showed up while waiting for a tow and was convinced that the timing belt snapped. Once I got the car towed to my grandpa's garage, I got the valve cover off and everything looks to be in good shape, including the timing belt (not worn, not shredded, it actually looks almost new). I'm starting to thing that maybe it jumped a tooth (or a few teeth), but even if it jumped timing, why would the alternator belt come off the crank pulley?

Re: What happened? Jumped timing?

Actually, I think the alternator belt was only a coincidense.

It might be your alternator, or the brushes inside not charging. Have you tried to measure the voltage on your battery? Because it seems that it ran on solo battery power untill the battery died. Just a thought..

Re: What happened? Jumped timing?

harmonic balancer issue? if it's slipping could cause timing to move and or affect the other belt. is your hb 2 pieces? (inner/outer portions).

i had a harmonic balancer separate on a t-bird once. wrecked a motor.

Re: What happened? Jumped timing?

After a little more investigating, it looks like the hb might be the culprit. When you turn the motor over you can see that its severely out of round, or maybe just completely broken, can't get a great view of it. Apparently this is pretty common on hondas though.

Re: What happened? Jumped timing?

I hope so, don't know for sure yet. I haven't dug into it too deep, my uncle just noticed the wobbly H/B when I turned it over last night, and everything looked good when I removed the valve cover. I have the day off tomorrow so I'm going to tear into it and see what's going on.

P.S. - Anyone with a spare H23 crank pulley lying around, let me know ;)

Re: What happened? Jumped timing?

Stripped crank pulley bolt threads, loose bolt, or what I'm putting money on..... a wobbly crank pulley caused by a worn key/keyway.
