Crank Pulley failures - how many miles?

Crank Pulley failures - how many miles?
seeing all the posts about broken crank pulleys is worrisome. makes me think about proactively replacing mine before it goes. 99 w/ 155k mi.
for those who have had them break - at what mileage are they breaking?
also dreading the figgin water pump.

99 max with 226k. i heard something not right one day & thought i saw the compressor wobbling. no problem, bypassed the compressor. then right after noticed it was the crank pulley wobbling. so i bought a used crank pulley from an inmate on here. it sat on the bench for maybe a week. noticed a noise only on start-up the last 3-4 times. then went to start it & the pulley snapped off.
so in my case, i heard the noise & shortly after it failed.

Just do a visual inspection. If the rubber is starting to separate from the metal, replace the pulley as a preventative measure.

159K is when mine went (like 2 weeks ago, lol).
Heard an awful noise one day coming from the pulleys, got down and looked and was able to move the crank pulley with my hand from side to side, so I got a new one and swapped it in. Problem solved.

It is unbolt and replace, but it's on there pretty tight and needs to be re-torqued properly.
I'm suprised these cars use a two-piece pulley like that. I just pulled a motor on a '96 and the crank pulley was completely separated. Had about 185K on the motor. It also chewed up the A/C comp pulley, not sure which went first though.

I did it with the engine on a stand, and it took a jack handle on the breaker bar to get it off.

Opposite way used to tighten it back also...I wonder if something like this is sold now...if not, I gotta try and find him to get one made for myself...

The make piston stops which are similar to what your talking about. I know who did something like that with a piston stop. I later had the cylinder head off the motor, their was an indent in the piston. It wasn't bad, but I wouldn't do or recommend it.

You can also jam the flywheel or just use an impact wrench to remove the bolt.
Mine went at 217k and I believe it was really caused by an oil leak in the area that got on the rubber element.
I've yet to replace mine, it's getting to the top of my list.

a whole host of nasties with all that starter torque

Both of my VQ30's ('97 Maxima & '00 I30) are right at 140,000 miles with no apparent problems so far. However, the I30 does have a "whirring" sound I have not been able to locate (but ruled out alternator, tensioner, AC pulley). I'll have to inspect the crank pulley closely.

Crank pulley
Mine is gone. Didn't hear much but changed a bad serpentine belt and when I shredded the new one I started looking for the cause! Not my proudest moment. But anyway have to figure out how to get old pulley off. Has to be on there tight. Probably try impact tools. Anyway 95 maxi with 148k.

Mine went out a month ago, at 226k km's.
It was making weird noises for the last couple of days like metal grinding on metal at high speed. Imagine when a train stops into a station, smth like that .
One morning I started the car a a big bang and a pulley was spinning in front of my car.
So yea, when you hear the noise change it

Mine lost it a year ago, at about 132K miles. I suspect that this is more age related than mileage, as mine was almost 16 years old at the time. As others wrote, you do get some warning.
Transmission in gear and hold the brakes only works with manual transmissions.
Breaker bar held steady to the floor while wife bumps the starter works well to take the bolt off, that is what I did. But I had no way to tighten it back on, I had to borrow an impact wrench to do that.
