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

The serpentine belt is falling off durning wet weather

Hi Brenda !
I am sorry to hear about your problem with your 99 voyagers serpentine belt falling off in wet weather !
I am suggesting that the harmonic ballancer is at fault.
The harmonic ballancer is the pully that is on the engines output shaft on the front of the engine (the transmission is on the back side of the engine).
I am assuming that the rubber bushing that holds the outer ring with the serpentine belt pully on it has detatched and is causing a misallignment of the pully to the belt , causing the belt to glide off.
I am unsure how this relates to wet weather though...

Inspect the pully by turning the vehicle OFF and looking in the wheel well behind the tire. There is a plastic shield there to keep the water durring wet weather from spraying on the belt and accesories... look and see if the plastic has been damaged (possibly a round 'rub thru' where the harmonic ballancer pully rubbed it ?).

1998 grand cherokee 4.0 eng. crank shaft pulley,is there a back piece for the belt to go on?

are you talking about the serpentine belt or the timing chains, the serpentine belt is what drives the alternator,power steer,water pump, and goes around a few idlers. and around crank pulley that is in front of harmonic balancer. Did the belt fall off? is the pulley missing? cause it should be very self explanatory and visual.

Timing marks1994 s10 blazer v-6 4.3 litter

Hi: I assume your trying to locate your timing marks. On the Bottom Pully on your Engine where your Belt or Belts run, Behind where the Pully is Mounted to is your Harmonica Balancer ,On that Harmonic Balancer you'll find your Timing Marks,Clean it all the way around it with a Degreaser wipe it off rotate your enging a bit at a time and line up your timing marks with the Pointer which you'll also see ,It just looks like a half Triangle or a Round Pin. Pointing towards your Timing Marks. TDC =Top Dead Center.
