I'm trying to remove a harmonic balancer. I've got to the point of taking it off. The pulley remover is placed. But the bolt when completely down only turns the balancer. How to fix please

I'm removing the harmonic balancer off a 3800 series two engine. I have to replace a crankshaft pos. Sensor. Now I've used a pulley remover and it won't pop off. Any suggestions to remove it without destroying it?

Are you using a gear puller or an actual harmonic bal. puller? You can use air tools(carefully), or to hold the balancer/pulley still, use a chain wrench with an old belt wrapped around to prevent damage. I would not recommend a 2 or 3 jaw type gear puller.

    I am. But I'm having the issue of popping the balancer off. I just need to know. Could I use a rubber mallet on it

  • Richard Church Oct 17, 2015

    You could beat on it with a mallet, I doubt it will help. You just need to get the initial "pop" to free it, and then it should come off slowly but surely. Use of penetrating oil will help.

    I'll try some pb blaster. But my only issue is the pulley remover goes so far it locks into the crankshaft well. I am still unsure why but the compression bolt on the set will go in. The yokes completely adjusted. Its just that it keeps going to the point where the whole harmonic balancer moves. There is no tension or push from it. But all other gm 3800 motors don't have this problem with the remover. Do you know why?

  • Richard Church Oct 18, 2015

    Are you running out of threads on the drive screw/bolt? Or is just the outer part of the balancer coming off?

  • Damion Donovan
    Damion Donovan Oct 18, 2015

    I'm running out of thread to keep ratcheting it in to the yoke. It uses all the thread but it's like I need a longer bolt or something with a different head. But the don't sell any of those unless I buy a jaw puller. It might work. But I don't want to get it off an me not have a harmonic balancer because of damage. I was also worried that there might be something else wrong. No videos on pressed harmonic balancers never have the bolt go all the way in.

    But yea I'm running out of thread.

  • Richard Church Oct 19, 2015

    If I think what you're saying, back off the drive screw and install the balancer bolt but not all the way. Now the drive screw will be pressing on the crank bolt head, it should give you that extra depth you need.

    Damion Donovan Oct 19, 2015

    I'm definitely gonna try tomorrow. I hope this works. Do you know by any chance where I could get a longer drive bolt for later endeavors?

  • Richard Church Oct 20, 2015

    An industrial hardware store perhaps. Finding the right thread pitch might be hard. If you want to get creative, find a bolt with the same pitch and size, cut off the head and join it to your existing drive bolt with a threaded sleeve. Good Luck.

Taurus crankshaft pulley

Yes you need a 'Harmonic Balance Puller' If you mean the centre bolt that holds the harmonic balancer to the crank. No not reveresed. Can be removed by placing a socket on bolt head and using a long handle placed against chassis. Touch the starter key to loosen.

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.

Why is it hard to get balancer pulley off 98 neon? Tried a pulley puller and impact. Still no luck. What should I do?

Did you take out the center bolt? You have to remove the center bolt, then use a harmonic balancer puller. Not the two or three armed pulley puller, but a harmonic balancer pulley puller-the pullers with jaws that hook around the outside of pulley can ruin a harmonic balancer.
Use the impact gun to remove the center bolt. You won't need an impact gun to remove the balancer pulley. The balancer puller will take it right off the crankshaft, no problem.

How to change crankshaft sensor on 1999 grand price gt

To get to the sensor, the harmonic balancer pulley on the crankshaft has to be removed. The center bolt on the harmonic balancer is on very tight. To loosen without an impact wrench, remove starter motor and wedge a piece of wood against the flywheel, or use a pry bar and hold the ring gear on the flywheel rigid, while loosening the crank bolt. The engine will try to turn backward when you loosen the crank bolt, so you have to hold the flywheel rigid. Once the bolt is removed, see if you can get the harmonic balancer pulley off without a gear puller. Just try tapping it to see if it slides off, or use two screwdrivers on each side behind the pulley and see if you can start it sliding off. If it is on very tight, as many are, you will have to get hold of a harmonic balancer removal tool-a simple, inexpensive puller that bolts onto pulley and can be drawn off. You might be able to rent the tool too.
BTW, you will need to have the wheel removed from passenger side, and the inner fender cover removed to get to the crankshaft. Once the pulley is off you can unbolt the sensor and put the new one on. GM recommends using a sensor alignment tool to install, because the thin vanes on the back of the harmonic balancer pass through the sensor, and if not aligned right could damage one or the other. If you don't have the tool, put the sensor on loosely mounted, just snugged up finger tight, then test the pulley will slide through the sensor slots without touching either side of sensor. If it looks right, tighten down the sensor in place, install the harmonic balancer pulley and tighten the center crank bolt to about 105 foot pounds.
Wedge the flywheel again so the engine won't turn when tightening the crankshaft bolt.
Good luck, and hope you get it.

Ho to replace Harmonic Balancer/Crank Pulley

the pulley will be either pressed on or bolted on
if pressed on you will need a harmonic balancer puller to get it off and space to swing a hammer to put it back on
if bolted it will be torqued to up to 90ftlb so holding the crank to undo the nut is a problem so get a 1/2 " impact gun for the job
you will need space for the tools so look at what has to be removed first
next there is a crankshaft position sensor behind the pulley so be careful with wires in that area
some engines have the pulley bolted to a crank hub with 3 or 4 small bolts in which case the job gets simpler
the item to watch out for is the drive key in the crank shaft as it can fall out of place and fall inside the seal especially when refitting the balancer

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

I need a how to to change harmonic balancer for 1995 nissan maxima. step by step

First remove right front tire and support vehicle with a jack stand. Remove splash guard lower portion near the harmonic balancer. Remove all drive belts. First remove the A/C alternator belt. Loosen the 14mm bolt at the front of the belt tenioner and then loosen the tensioner bolt (it is the one that stands out, you use a socket on it.). The power steering adjuster bolt with be gained from the bottom. It has a 12mm bolt head on it. You will break the jamb bolt loose first and then loosen the adjusting bolt. Pull down on the belt the help move it after you've loosened it some.Then remove harmonic balancer bolt (19mm).If the harmonic balancer will not slide off the crankshaft then use a two finger gear puller. Place the harmonic balancer bolt back in the crankshaft but do not tighten it. Leave it about a half inch from being all the way in. Next place the puller onto the harmonic balancer (one finger on each side securely press into the belt groove. The center puller bolt will rest against the harmonic balancer bolt head. Tighten the puller bolt and make sure the harmonice balancer bolt does not turn. The balancer should come off at this point.
