2000 lude crankshaft pulley simple question

if someone know or can just take a look for me. I just fixed my crank pulley and put it back on. it seems to be very tight but looks as if it is wiggling left and right just a tad. I wasnt sure if this is normal someone with a h22 base motor check that out really qucik

Re: 2000 lude crankshaft pulley simple question

The stock bolt that holds the crank pulley in place is made precisely for the engine it's in, there's a washer fitted onto the bolt and the thread of the bolt itself doesn't run under the washer so you can't really "over" tighten it by accident, so that's not the problem. When you took the pulley off there's supposed to be a "key", basically a small metal tab that slots into the pulley itself because the ones on the H22 aren't compression fit pulleys like you'd find on lots of other engines. When I changed mine the key was worn down so I had to get a new one. That could be your problem. Either that or you didn't tighten it enough..if you did it by hand then that's DEFINITELY the problem, they need to be done with a good strong impact driver. If you take it back off and it IS the metal key I was saying that's worn down then you should check the pulley itself because usually one won't wear without damage to the other. In any case, if that's what it is you need a new key for starters, and if you can't pull the old one out...you're screwed :D If you can then pull it out, go to a garage and get them to cut you a new one, most places should have key stock. After that if your pulley is damaged too you need a new one.

Lots of folks might not think that's a problem, a wobbly pulley. But it's a crank pulley, which is otherwise known as a harmonic balance. It's a special pulley made to counter-balance the crankshaft, which is naturally unstable, and thus stop it from tearing your engine apart. In short, bad or wobbly crank pulley could = engine death....so for the sake of a 150$ flywheel (or cheaper from wrecker) and some time, I'd say you should make damn sure you've got a good working one that doesn't wobble :D


EDIT: One last thing I thought of, if you check all that and everything SEEMS fine and it still wobbles then the pulley itself could be damaged. If you look at it when it's off it's not a solid metal pulley, there's a rubber ring that separates the inner and outer pieces of metal, these can sometimes wear out and begin to brake down, and if all else fails that might be what's going on. At that point it's safest to get a new one..like I said, bad pulley = boom!

You can tighten it by hand just make sure you have a good torque wrench to make sure. I do agree on the wobbly pulley = death part though.

Uh..I couldn't tighten mine by hand? As soon as it got tight enough the crank turned as I turned the wrench. I had read about the torque spec too but decided getting it as tight as possible with the impact was good, especially considering that it tightens itself down while the crank is turning as well.

Re: 2000 lude crankshaft pulley simple question

i had brought it up to my buddies place and raised it because about 5 days ago the bolt for my crank pulley had made itself loose and actaully slipped off on my way to work and luckily was still dangling from the engine when i pulled into a parking spot. We got it towed like right away to my friends shop not knowing exactly what the problem was and a mechanic there said to tighten the bolt and i should be good to goooo............


Want me to get a video up of the pulley wiggling.........

That's why there is a special tool to insert into the pulley and either contact the ground, or bolt to the car. If it is not torqued properly, it WILL come out.

Yea I knew that..for some reason it slipped my mind when I wrote that. I've actually been meaning to go get that particular tool from a buddy of mine that has one so I can make sure it's on properly, lol.
