Good luck man, I had the pulley go out on mine yesterday so I kinda understand what your going through. Good luck.

if your crank was bent ur motor would be screwd trust me lol and if u say u got a new pully but still wobles u might have some problems and i think the clicking noise is because ur cranke wobles it is ment to be perfectly balanced otherwise all heck breaks lose lol

 

[MountianLude]

OK so the thread on the bolt may be ****ed from whoever worked on it before overtightning the bolt?

Get a machine shop to inspect it.

 

[pjschmitt]

You can pull the crank out without rremiving the pistons or the head. Get it out and take it to a machine shop for inspection. They can do whatever it needs. They can balance it or have it balanced. You can put in new rod and main bearings, reassemble when repaired and pop it back in the car. Two guys with the right tools and some knowledge = one day work. So one half day to pull it and get the crank out, one half day to put back together and see how it runs. The crank can also be polished and set up to run oversize bearings too.

I just had this same situation happen to me, and my buddy that replaced my pulley said I need to have my crankshaft balanced. Does anyone know of a good shop in the socal area that will do this at a good price?

 

[minilogoguy18]

^Your buddy doesn't know wtf he's talking about, if you're having vibration still from the crank you either spun a main bearing or the thrust washers are bad making the crank walk back and forth.

^Your buddy doesn't know wtf he's talking about, if you're having vibration still from the crank you either spun a main bearing or the thrust washers are bad making the crank walk back and forth.

So I'm assuming that I would need to replace those either way if they are bad, so would you recommend getting the crack balance since it would be out anyway?

 

[NuisanceLude]

I have the same slight Crank Pulley woble, but at a slight acceleration it straightens out. And this is just by me looking at it.. I can feel a vibration and can see the pulley dance a little not much.. I figured this was just basic wear after the T belt jobs since the car still runs strong.

Sorry for the up but I have some infos for you.

I'm in contact with 3 peoples (in France) that have this ****ing pulley problem, you can fix it with a new pulley and a new key but do it soon if you don't want to damage the place on the crank where the key is supposed to go. I've seen a pulley where that place were 2 times bigger than a brand new pulley.

I'll change mine this weekend, I'll let you know if it can held someone.

crankshaft pulley

hey guys. i got a 01 prelude. Pulley is wobbly. i took apart the belts and it seems like the bigger outer ring is completely detached but from videos and online research it looks like it originally comes in one piece. not sure if i should replace the whole thing or if I'm suppose to get some kinda rubber to put between the pieces so they flush. What would you guys suggest?!?!

 

[kemmerer91]

So i had my crank pulley come lose and i got lucky not to damage anything key bolt belts and pulley all good still. So now im facing trying to get it tighten to 180 spec and bought the honda tool now my issue is that the frame is in the way to use this honda tool which is a bummer since i was ready to torque it up yesterday. I've seen people jimmy up the pulleys with different type of methods. Any method recommended that work?? Seems like i would have to drop the drive side engine to fit the honda tool. I can have picture if needed. Any help on how to solve this problem wold be greatly appreciated. 1999 honda Prelude SH

I think you have it with dropping that side of the engine. It's been forever since I did my timing belt, but I seem to recall that was required. Interestingly the manual doesn't seem to mention it, but looking back at my notes it is required.

Good luck with it.

About a year ago my crank pulley fell off. All I knew at the time was I lost power steering and there was a noise in the engine bay. I was in stop and go traffic and immediately pulled over then got it towed.

The mechanic showed me what the problem was. The pulley was out but had not exited the vehicle. The bolt was still there, too. He also showed me that the pulley's splines were worn down to next to nothing. He put it back on, used Loctite Red, torqued it, and that was all he could do.

The car drives okay except when the A/C is on. The engine's power is uneven. I figure the pulley is slipping under the load of the accessories and A/C. I plan on doing my own timing belt job soon and would like to use the opportunity to deal with the pulley. Maybe the crank is okay and all I need is a fresh pulley.

Any suggestions?

 

[tummydoc]

If the splines were worn, it suggests someone forgot to replace the Woodruff key when they worked on the car, likely changing the timing belt. Were the splines worn on the crank also or just the pulley? If the crankshaft is ok, I'd replace the harmonic balancer and make sure you place a Woodruff key. Red Locktite wasnt the right fix.

 

[m610]

I'll know more when I get in there to replace the timing belt.

The dealership is the only place that has worked on the engine. They did my timing belt last time.

 

[Mañana]

I may be mistaken, but at least on my 2001 I found it interesting that although the pulley had splines the crank end did not; it relies on only the woodruff key and friction. My suspicion as to why, is that perhaps this decreased the metal to metal contact between pulley and crank to ease removal, but of course that’s just a guess.

If the pulley was wobbling or slipping I think I fear the worst. I think that once they start moving about they mangle the woodruff key slot in the Crank. I hope you are lucky and it’s only the pulley and key.

The early Miata with a short nose crank suffered much the same thing and there are some fixes out there, but not really sure how much success they had.

A search for Miata Crankshaft Repair will show their situation.....

Here is an image of my crank end where you can see the marks remaining from the splined pulley.

Good luck with it, please let us know how things go.

 

[tummydoc]

I think you're correct that the crank end is smooth now that I think about it. Been a while since i had my crank pulley off, but if the crank end was splined it wouldn't really need the key.
Maybe Kabuki will chime in, he'd know.

 

[m610]

I'll know more when I get in there to change the timing belt.

The dealer is the only shop that has ever worked on the engine.
