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.

How to replace crankpully on 3300 olbs


The harmonic balancer on these engines is now press fit onto the crankshaft and requires the use of Tool J-38197 for removal. The torque specification to be used during installation has also been revised. The procedure to be used when replacing the crank sensor is as follows:

REMOVAL






  1. Disconnect serpentine belt from crankshaft pulley.


  2. Raise vehicle on hoist.


  3. Remove right front tire and wheel assembly.


  4. Remove right inner fender access cover.


  5. Using 28 mm socket, remove crankshaft harmonic balancer retaining bolt.


  6. Remove crankshaft harmonic balancer using Tool (J-38197).


  7. Remove foreign object deflector (DO NOT use pry bar).


  8. Disconnect sensor electrical connector.


  9. Remove sensor and pedestal from block face.


  10. Remove sensor from pedestal




INSTALLATION






  1. Loosely install crankshaft sensor on pedestal.


  2. Position sensor with pedestal attached on Tool J-37089.


  3. Position tool on crankshaft.


  4. Install bolts to hold pedestal to block face, torque to (18-26 lb. ft.).


  5. Torque pedestal pinch bolt to (26-44 lbs. in.).


  6. Remove Tool J-37089.


  7. Install foreign object deflector.


  8. Place Tool J-37089 on harmonic balancer and turn. If any vane of the harmonic balancer touches the tool, replace the balancer assembly.


  9. Install balancer on crankshaft.


  10. Apply thread sealer GM #(NNN) NNN-NNNNor equivalent to threads of crankshaft balancer bolt. Torque bolt to + 56 degrees (104 lb. ft. + 56 degrees).


  11. Install inner fender shield.


  12. Install tire and wheel assembly. Torque lug nuts to (104 lb. ft.).

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 have a ford f-250 with 460 engine. 1983 model and have to replace the front crank seal. how much trouble is it?I already have the radiator off and replacing it.


You'll need to remove the crankshaft pulley and the harmonic balancer, which you'll need a harmonic balancer removal tool. The center bolt is usually on really tight. You can use a seal puller to remove the crankshaft seal from the timing cover.

How do you replace the harmonic balancer pulley on the 2000 oldsmobile intrigue


The short answer to your question is:

1. Raise the car on the passenger side and remove the front wheel.
2. Remove the belts on the harmonic balancer.
3. Remove the retaining bolt.
4. With a puller, jack the harmonic balancer off of the crank shaft. You can rent a puller at your local auto parts store. It is easiest to access the harmonic balancer through the fender, hence the need to remove the wheel.
5. You should also consider replacing the seal around the harmonic balancer to minimize the possibility of a leak later.
6. Install the new harmonic balancer and tighten the retaining bolt to the specified torque (I don't know this off the top of my head).
7. Replace the belts and wheel, and voila...mission accomplished.

This was a short answer to your question. You may wish to consult a repair manual for illustrations, torque specifications, additional instructions, etc. This job is not for the faint of heart. Good luck!

Front crankshaft seal, 1989 hilux


Hello,

Yes, it's possible to change the seal after removing the balancer.
If the balancer shows signs of scratching, wear at the place of the seal, change that part too!

To remove the old seal, drill 2 small opposite holes in the seal flange ( there is metal in it ).
Screw 2 (parker) screws in the holes, so you can pull the seal out gently.
Grease the new seals' inner race, and put some sealant paste to the external race.
Push it back in place with a wooden piece ( drill a hole in the center for the crankshaft end )
Grease the outher race of the balancer. This will help the seal come gently into place.

Good luck!
