SOURCE: V groove pulley slipped off of harmonic balancer of 1999 Grand Am

After checking around, I decided to replace the harmonic balancer. I had a repair shop fix it for me and I think they over charged for the part. But, at least I'm on the road again. This Grand Am has 227,000 miles and still runs pretty good.

Make sure you check timing and the belt. if it spun don't risk putting it back on. Hope you got a new key. TIMING is important so you don't stick a valve through the top of your piston

SOURCE: balancer shaft came apart

Sounds like the harmonic balancer - that also serves as the timing on a non distributor car has stripped the threads out. This usually - not always but usually requires a new crank shaft. Might be cheaper to just get a used engine.
take down the vin number and ask the local dealer if there have been any recalls or service bulletins

was the threads clean and dry of oil? thread locker needs to be a lone substance...no presence of oil, ...there technically is even a primer for thread lock.....bolt may be a torque to yeild bolt which means replace it every time its loosened...... both sets of threads must be dry and clean ,
and use a torque wrench to assure its correct torque

My crank pulley is loose on 2009 jeep Cherokee how do I tighten


There is one bolt in center of pulley/harmonic balancer. Sounds like the harmonic balancer has started going bad..if bolt in center of pulley is loose...which is fairly uncommon tighten which you just tighten Iike any other bolt. If it is tight then you will need the replacement. Replacement is a good bit more involved. Radiator has to be removed, special tool, harmonic balancer pulley remover is required..it will remove pulley. Then you line up pulley with keyway..tap on with rubber hammer until pulley is on far enough for bolt to be started..tighten the bolt and it pulls the pulley all the way into place.

Tip

Replacing the Crankshaft and Camshaft sensors on a 1991 and later Buick Park...


If your car is misfiring in a rhythmical pattern when you first start it up for the day or dieing when engine is hot, it could mean your Camshaft or Crankshaft sensors need replacement.

Important, disconnect negative cable from the battery before doing any work on electrical system. Wear safety goggles.

Tools recommended:
Break Bar, Torque Wrench, ratchet driver and a full metrics ratchet socket set, one Q tip, large straight blade screwdriver, ratchet extension and adapters if needed.

First we'll start with the easiest and cheapest of the two sensors.

Replacing the camshaft sensor:

The camshaft sensor is located on the right side of the engine, behind the water pump pulley.

1. Loosen the screws to the water pump pulley with a breaker bar before removing the serpentine belt. Always turn counter clockwise to loosen.

2.Remove the serpentine belt via the belt tension-er.

3.Use a regular ratchet driver to finish removing the belt pulley from the water pump.

4.Remove the bolt holding the camshaft sensor in place and disconnect electrical connector. Secure the connector with a clothes pin so you don't lose it down in the engine compartment. Clean around the sensor to avoid getting dirt in the engine.

5. Pull the camshaft sensor straight out with a slight twisting motion.

6. Lightly lubricate the O-Ring on the new sensor with fresh motor oil, and install in the engine.

7. installation is the reverse of removal.

Crankshaft
Sensor:

1. Jack up the front passenger side of the car and safely support it on jack-stands.

2.Remove the tire, remove the inner tire well splash guard cover.

3.Before removing serpentine belt, loosen the center bolt on the harmonic balancer/vibration dampener. (crankshaft pulley)

4. Remove serpentine belt via the belt tensioner.

5.Finish loosening and remove the bolt from the harmonic balancer.
Have an assistant help you, using care not to let the weight of the harmonic balancer rest on the bolt as it can be damaged. Gently pry it of with a straight blade screwdriver. Leave the woodruff key in the crankshaft. Use care to not damage the crankshaft during removal as oil leakage could result. Mark the relationship between the crankshaft and the pulley, so you will be able to line the pulley up just right during re -installation.

6. Disconnect the electrical connector from the crankshaft sensor, secure the connector with clothes pin and loosen the bolts holding the sensor pedestal in place.

7.Separate the old sensor from the pedestal, and install the new sensor, just the same way the old sensor came out. Using the suggested crankshaft sensor alignment tool on the back of the harmonic balancer, making sure the fins on the harmonic balancer pass through the sensor's slot and don't hit it. If any fins on the back side of the harmonic balancer are bent, damaged, or missing, replace the harmonic balancer assembly.

Installation is the reverse of removal. It is imperative the crankshaft sensor be aligned properly before engine start up to avoid damage. Use care not to over tighten bolts during installation. Always tighten to manufacturer's recommended torque.

I have a 1999 Chrysler Cirrus. The serpentine belt came off that goes to the alternator and the air conditioner unit, I was told by a mechanic that the dampner pulley is bad. Some autopart sites have a...


Hi, assuming you have the 2.5 liter engine, your damper is integral to the pulley assembly as shown in the second figure below, so there is only one part involved. You can see an example of the part here: http://www.autozone.com/autozone/parts/Dorman-Harmonic-Balancer/1999-Chrysler-Cirrus/_/N-jddk1Z93y2h?counter=0&itemIdentifier=917091_0_0_
If you look carefully at the pic below, you can see the rubber torus inside the pulley. The rubber is what fails and causes the pulley to wobble. You may need to borrow a puller to get the pulley off.

2.5L Engine
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Disconnect battery negative cable from remote negative terminal on shock tower and properly isolate to prevent accidental reconnection.
  3. Remove or disconnect the following:

    Belt splash shield Accessory drive belts. Refer to Belts. Crankshaft center bolt and remove crankshaft damper.

Where is the crankshaft sensor on a 3.8L in a 97 buick lesaber


Hi,
The sensor is located to the right of the crankshaft behind the vibration dampner (harmonic balancer). You will need a balancer puller and a special tool to space the new sensor correctly.
(can be done also with eye spacing, but the tool is recommended to ensure proper spacing as to prevent damage to new sensor and / or harmonic balancer.) You will also need a strap wrench to hold balancer pulley in place while removing and re-installing balancer to crankshaft bolt. (helper required)

Procedure for replacement:
Remove negative battery cable.
Set parking (emergency) brake.
Release tension on serpentine drive belt and remove belt from harmonic balancer pulley. ( large pulley at bottom of engine)
Break loose lug nuts on passenger side front tire, do not remove bolts yet.
Raise and support vehicle on passenger side, remove wheel.
Remove plastic splash guard (cover) from passenger side wheel well.
Remove dampner / balancer center retaining bolt (counterclockwise, it is torqued very tight.) Use a strap wrench around pulley and have a helper hold that in place while using a 1/2" breaker bar and socket to turn pulley bolt out of crankshaft. Be careful not to rotate engine in a counterclockwise direction while breaking the bolt loose.
Using balancer puller, remove dampner / balancer pulley from engine.
You will now see the crank sensor to the right of the crankshaft bolted to the timing cover.
Disconnect sensor wiring and remove retaining bolts, remove sensor.
Put new sensor in place and screw in bolts, do not tighten them yet.
Reconnect wiring to sensor.
Now use special tool to properly space sensor. If you cannot find one at the parts store, you can space the sensor with the balancer pully held in place (not installed yet) and space the sensor evenly with the veins on the hub of the balancer pulley. Take your time and be sure it is as evenly spaced as possible.
Tighten sensor bolts.
Clean balancer hub free of any oil and dirt deposits using brake or carbeurator cleaner.
Reinstall balancer to crankshaft by tapping around the inner surface of pulley with a rubber hammer.
It is a press fit, so be sure you have it started evenly and progress slowly in a circular motion to ensure you are keeping it aligned straight with the crankshaft.
Reinstall balancer bolt using the same method as removal, torque bolt to 110 foot pounds, then tap around balancer again twice with rubber hammer, turn the engine 2 full revolutions clockwise using the balancer to crankshaft bolt, then tighten bolt an additional 1/4 turn.
Replace splash guard, put wheel on tightening lugs to finger tight and then wrench tight in a star pattern.
Lower vehicle until wheel makes contact with floor, tighten lug nuts to 115 foot pounds in a star pattern using a torque wrench.
Fully lower vehicle, remove jack.
Re-install serpentine drive belt
Re-connect negative battery cable.

End of procedure....Hope that helps!.....Mike
