Inspection Procedure
Use the following procedure to correct engine flywheel and torque converter
imbalance:
| • | Inspect for missing or loose converter-to-engine flywheel bolts.
Tighten the bolts or replace the bolts as necessary. |
| • | Inspect the converter for damage. Replace the converter if the
converter is damaged. |
| • | Inspect the converter for missing balance weights. Replace the
converter if the balance weights are missing. |
| • | Change the position of the converter-to-engine flywheel 120 degrees
at a time in order to cancel out engine and converter imbalance. Check for
vibration improvements in each position. |
| | Important: Ensure that the bolts are not bottoming in the holes. If the bolts bottom,
the cover could be dented and the internal clutch facing could be damaged.
After adding washers, always rotate the converter by hand in order to check
for clearance.
|
| • | Leave the converter-to-engine flywheel in the best balanced
position if the unbalanced condition still exists. Install longer flywheel-to-converter
bolts. Add or remove washers until the best balance is achieved. |
