Thumbs down Crankshaft Pulley

Does anyone have a new crankshaft pulley for a 1995-97 Honda Accord EX-V6 lying around?

I was getting some videos ready to post in an effort to get some help on a problem with the power steering belt when I noticed the crankshaft pulley wobbling.

Here's the run down:

Here's the noise:

At start-up:

After a few seconds after start-up, I have my epiphany and realize the crankshaft pulley isn't supposed to be wobbling:

Here is my attempt to video the wobble, but I only have a Class 4 microSDHC card in my EVO so the write speed looses a few frames per second and then photobucket degrades the video further, but here it is anyways:

Thumbs up All Fixed!

I got the parts Friday, but have been too busy to do the work.



Majestic sent me an old Power Steering (PS) belt. Bando doesn't make a 4PK1137 sized Rib-Ace Belt any longer. That size has been superseded by the 8mm larger 4PK1145 size. Both fit.


Today, the Crankshaft Pulley forced my hand. I was pulling out of the driveway to run an errand and the steering became stiff and then I heard something hit the firewall. I pulled over and turned it off only to find the PS belt had shredded, the A/C belt was shredding and rolling off the Crankshaft Pulley, and the Alternator belt was just fine. I turned the car back on and slowly pulled it back into the driveway; I called to reschedule my errand for tomorrow so I could spend the time to do this now.

Out with the old:



The old Crankshaft Pulley next to the new, see how the outer ring has separated at the Harmonic Balancer:



Here's the damaged goods and the new-new:

No more belt noise!:

Note my hydraulic tappets are so dirty the motor sounds like a diesel in training. I have it scheduled for the next timing belt change, but it is so loud that I get real paranoid about oil flow in the head and constantly check the oil level; I am fearful of scoring the Crankshaft or Camshaft.

Noisy Tappets

I had a feeling someone would say something about the noisy tappets, so I took a video of the motor warm after driving on the highway. Typical dirty tappets, they get quiet after the motor oil warms up and also at high RPMs.

On the Legend forums, they say the noisy tappets won't cause any harm, but I don't like all that noise. I heard thicker oil would make it better, but I don't see how. I've been contemplating a switch from Mobile1 Synthetic 5W20 to Mobile1 Synthetic 10W30 until I can clean them tappets out.

I believe the reason for thicker oil to relieve the noise issue is because the thicker viscosity would help alleviate the noise by adding more protection to the tappets. Keep the oil you are using unless if you feel that it is costing you more money. Clean out the tappets and see what happens. After all that, and the noise is still there, then change your oil to a thicker viscosity.

It is true that tappet noise won't harm your car, because I have heard other models of cars tappets making that noise without any significant damage.

our engines will make noise when they get older.
How to fix them ... Restore Engine Additive.
I use 5W40 Synthetic

It works magic and I use it on all my rides
All of them are silent.

Also, performing engine flushes really help.
I buy extra oil when on special just to re-flush inbetween oil changes

hope all is good with all you guys, been a while
