The bolt in the center on the damper is contra thread. to get it off use an impact (electric or air powered). and for the damper it is shot. you will have to replace it with a new or used one from a junk yard.

What damage does harmonic balance that is bad do


The harmonic balancer is basically a vibration dampened for the engine to eliminate engine vibration. The problem is that sometimes the actual ribbed pulley part on the balancer will separate from the rubber insert and slop around causing the belt the slop around with it. In turn the belt can fray or break. I would say its totally legit what they are saying. Just make sure you always ask to see the part after any work is done. Good luck

1996 Jeep Cherokee Sport - 6 Cyl /4.0 Liter - Crankshaft dampener fell off. Proceedure for reinstall?


You will have to buy a new pulley to crankshaft bolt and washer. Or did you find that as well when you picked up the damper? Probably fell off a long time earlier. Buy a used one from salvage, or get one from a Jeep dealer.
The damper should only go on one way. Or there may be a missing woodruff key. It would fit into a slot on the crankshaft, holding the pulley in a set position. If the woodruff key is missing, you will have to find one of them as well.
Working from underneath, remove the "belly pan" mounted below the front of the engine. Book says you MAY need to remove cooling fans and radiator for access-but that is for removing the old pulley with a pulling tool. You may be able to get it all back together without pulling the fans or radiator off. Put a little clean oil on the crankshaft, align the key slot of damper with crank key and tap the pulley on with a soft faced mallet or appropriate tool. Get the pulley on, tighten down the bolt tight as you can get it, then belts back on. Then go to a shop and have someone put an impact tool onto the bolt to torque it down to specs-80 FT-lbs.

LOOKS LIKE MY 99MAXIMA CRANKSHAFT PULLEY BELT BROKE AND THE PULLEY IS KINDA HANGING OFF SOME, WHAT AM i LOOKING AT? JUST BELT AND IS PULLEY OK OR REPLACEMENT OF BOTH? PLEASE HELP DONT WANT TO GET RIPPED...


If it's the main pulley that connects to the crankshaft and drives the serpentine belt, it's called the dampener pulley.
If the dampener pulley has worked loose or separated, you'll need to replace any damaged components, possibly including the pulley, mounting bolt and even the crankshaft and front engine housing could have been damaged if the pulley continued to turn while it was loose.
It could be as simple as tightening the bolt or as severe as a major engine rebuild. A mechanic can't know until he takes a look at it.

On a 2005 Hyundia Sonata, should the crank shaft pulley feel loose? I recently have gone through 3 steering wheel belts. I assumed the first belt frayed because it was old and brittle. The new belt...


No, there are no bearings in the crankshaft pulley. No, it's not a common problem. The pulley is simply loose!

First determine if the pulley bolts to the harmonic dampener or if it's all one piece.

If one piece, then there is probably 1 bolt in the center of the dished portion that has loosened. If not repaired, the harmonic dampener can fall off, possibly damaging the end of the crankshaft.

If it's not 1 piece, then there will probably 3 or maybe 4 bolts in a circular pattern around the edge of the pulley bolting it to the harmonic dampener. Check to make sure all bolts are there and tighten down. A flexible mechanics mirror comes in handy for seeing exactly whats in the dish of the pulley.

If I were you, I wouldn't start the engine until this is properly resolved.

Good luck!

How to install crank sensors


repair manuals are available from this site,or your library. this is not a simple repair. removing all needed the belts brackets maybe the ac compressor off to the side etc. removing the crankshaft dampener pulley=special tool= not to expensive and may but i dont think so a tool to put it back on.it should be rather large plastic part with metal teeth behind the pulley held on by two bolts.
