Replacing harmonic balancer and crankshaft sensor on 1992 Olds 88

I have a couple of questions regarding this job. First of all is the balancer bolt left handed or right threads? I have seen both in discussions. Secondly, is the sensor for this year one that needs to be adjusted or one that simply bolts into place with no adjustment? Info from a repair manual indicates the sensor that needs no alignment, but the sensor from online parts store look like the other. Your help would be greatly appreciated.

The bolt is a right hand thread. And the sensor is not adjustable. It is a straight forward install.

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.).


  13. Lower vehicle.


  14. Install serpentine belt.

I need to replace crank shaft timing sensor


  1. Disconnect the negative battery cable.
  2. Disconnect the electrical connector at the sensor.
  3. Using a 28mm socket and pull handle, rotate the harmonic balancer until any window in the interrupter is aligned with the crank sensor.
  4. Loosen the pinch bolt on the sensor pedestal until the sensor is free to slide.
  5. Remove the pedestal to the engine mounting bolts.
  6. While manipulating the sensor within the pedestal, carefully remove the sensor and pedestal as a unit. To install:
  7. Loosen the pinch bolt on the new sensor pedestal until the sensor is free to slide.
  8. Verify that the window in the interrupter is still in the correct place.
  9. Install the sensor and pedestal as a unit while making sure that the interrupter ring is aligned within the proper slot.
  10. Install the pedestal and tighten the engine mounting bolts to 22 ft. lbs. (30 Nm).
3X Sensor

  2. Remove the sensor harness connection to the sensor. Fig. 1: Unsecure the harness, then unfasten the bolt to remove the CKP sensor 86815102.gif

  3. Unsecure the sensor block bolt.
  4. Remove the Crankshaft Position (CKP) sensor from the vehicle. Inspect the O-ring for cracks and replace if needed. To install:
  5. Install the new O-ring if needed and lubricate with engine oil.
  6. Install the sensor into the hole in the block.
  7. Install the mounting screw and tighten to 71-88 inch lbs. (8-10 Nm).
  8. Attach the sensor harness connector, then connect the negative battery cable.
Dual Crank Sensor Sections 3 and 4 of this manual also cover testing, removal and installation, and adjustment of many computer controlled components.
  1. Disconnect the negative battery cable.

I have a 2000 Park Ave. with a basic 3.8 L engine. I have noticed recently that when I am driving, it will shutter and sometimes I will lose my tachometer on the dash. The other day it finally set a code...


The balancer will need to come off and a puller must be used to remove it after the bolt is taken out. Most crank sensors give trouble when they get hot and do not set a code . Remove and clean the battery cables ends . Clean battery terminals and replace bolts. what code was set?

Removing harmonic balancer & replacing crankshaft sensor


The bolt is right hand thread. I do believe it is adjustable. But you can readjust it if needed after the balance is installed from the bottom.
