2 days ago my belt started to squeek i thought it was from the all rain it seems to happen when i start up the car...but last night i continued to hear the noise i check under the hood and my crank is wobbling not like OMG but its not smooth so that is kind of important...how does it get loose? is it the belt is the pulley loose do i tighten it or what?

 

Coincidentally I have the same issue, with the belt squeeking in rain and all. I pulled the wheel and found 3 of the 4 bolts loose. I tightened them, but it still wobbles and the belt still squeeks, but not as much.

 

yeah i know a few other people that their belt squeeks in the rain...but the wobble is from what though do i replace the gear or is a bearing or something worn out?

 

I don't know. I would like to know that too. This weekend, I'm going to pull the pulley off and see if it's warped or something.

 

keep me posted on your findings lol

 

Typically the main pulley will wobble to a small degree. If it is pronounced and causing belt issues, the cause will most likely be the rubber damper that surrounds the pulley and belt the area (where the belt rides on.) It is sandwiched in between the parts. You should be able to visually verify if the rubber is degraded or dry rotted.

 

lol put me on the list, my belt was squeaking from the rain, so I figured and just now getting back from lunch my pulley is wobbling. Anyone have an update to their situation?

 

I broke on of the bolts off in mine which ended up causing a chain of events. I ended up having to replace the oil pump, timing sprocket, timing belt, serpentine belt, and of course the pulley.

 

Ugh, well I just have to drive it a half mile up the road to my friends where I can take a closer look and hopefully its just loose or maybe the rubber is shot and I can tighten it replace it later.

 

I plan on looking at it further this weekend, plus to verify that the timing belt pulley is tight/not wobbling. I'm going to pull the serpentine belt pulley and look to see if it's warped/bent. Maybe it's time for a dampner.

 

Maybe this is more common than I thought, as I just dealt with this same problem a couple of weeks ago. I had been getting some noise from the belt, but it looked in good shape and I figured I'd replace it when I got some time. Well went out one morning, started the car, and heard a lovely noise. Turns out my wobbly crank pulley was causing my belt to jump one groove on the alternator pulley. When I got it up in the air and started looking into it, I found out 3 of my 4 crank pulley bolts had sheared off and the 4th was loose. They must have been loose for a while as the thru holes in the pulley were egg shaped.

Anyways, I used "easy-outs" to get the bolt shanks out (drill a small hole, tap the easy-outs into the hole, turn counter-clockwise), bought an aluminum fluidampr off someone on the board (good time to upgrade, right?), new belt, new bolts, and put it back together. No problems so far, but I know I'll be checking those bolts regularly from now on. Oh, and since I have no idea where to get metric sized SAE grade 8 bolts (seriously, why the hell is a japanese car company using SAE grade metric fasteners?), I bought metric grade 10.9 (closer to SAE grade 8 than the more common metric grade 8.8 you'll find at a hardware store).

I still have no idea what caused it since the crank pulley has never been touched (was still on factory timing and accessory belts), but hopefully it's not a sign of something worse. The car's as smooth and quiet as an Evo can be now that it's all taken care of, so who knows.

 

Keep an eye on your timing belt. When mine got wobbly like that it pressed up against the timing sprocket and broke off part of the ring that seperates the two. Ended up taking small chunks out of the timing belt.

 

Yeah, I think it's time to upgrade. Thanks for the info.

 

ill be taking a look at mine today...hopefully mine are just loose i would hate to have replace more parts

 

So I noticed that after I tightened my bolts, the vibration has gradually gotten worse again. I looked at it with the engine running and it was shaking pretty badly. Today I decided, with the help of the weather, to actually pull it off and see if it was damaged somehow. Well the vibration, I'm assuming from the loose bolts, actually wore away the bolt holes. They're no longer round. It has pushed the little key on the timing belt pulley back into pulley, therefore it's not really being held in place. Definitely time for a new pulley.

If you're having the same issues, you might wanna get it checked out!
