2005 tahoe torque specification for harmonic balancer

For the vehicle that only you know what it is! :>D

Torque Ratings Smaller Chevy models should have the harmonic damper bolt set to 60 foot-pounds. Larger Chevy vehicles should have a torque of 85 foot-pounds. Hemi426, smaller Chrysler and larger Chrysler motors should have a harmonic damper bolt set to 135 food-pounds.

Harmonic Balancer Torque Specs - It Still Runs

Here is a post with the torque specs. https://www.taurusclub.com/forum/82-maintenance-repair/254498-need-torque-specs-harmonic-balancer.html

Go to autozone.com, register for free and list this vehicle. Then you can get some repair procedures and specs for torque. Once your vehicle is listed, go to "repair guides" to find the specs.

It would probably be best. My info says 76 ft lbs

Any other way, too much liability, involved. If you choose not to use a torque wrench the responsibility/liability is yours.

you need the Chilton book for your car go to auto zone , advance all the auto stores carry them and look in the torque specifications section it is in there

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.).



13. Lower vehicle.



14. Install serpentine belt.

YOU NEED A HARMONIC BALANCER PULLER TOOL AND A 15M SIX POINT SOCKET TO REMOVE HARMONIC BALANCER BOLT.TURN OFF RADIO AND REMOVE THE DRIVE BELT AND REMOVE THE NEGATIVE BATTERY CABLE. REMOVE THE STARTER SO YOU CAN PUT A LARGE SCREW DRIVER OR LARGE PUNCH TO STICK IN ONE OF THE FLY WHEEL HOLES TO KEEP ENGINE FROM TURNING WHEN YOU LOOSEN THE HARMONIC BALANCE BOLT. ALSO SCREW DRIVER AND PUNCH CAN KEEP ENGINE FROM TURNING WHEN REMOVER THE HARMONIC BALANCER. YOU WILL NEED A HELPER TO HOLD PUNCH OR SCREW DRIVER WHILE YOU LOOSEN THE BOLT. YOU CAN GO TO SEARS OR ANY AUTO PARTS STORE AND BUY HARMONIC BALANCER PULLER.TORQUE HARMONIC BALANCER BOLT TO 76 FT LBS.

change the driveshaft yoke

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!
