- Incorrect Starter: Ensure that the starter you have installed is compatible with your 1989 Ford Bronco 2 2.9L. Check the part number and specifications to make sure it's the right one.
- Damaged Starter Gear: Inspect the starter gear for damage or wear. If the gear is damaged or worn, it may not engage the flywheel properly, causing the starter to push the flywheel.
- Misalignment: Check if the starter is properly aligned with the flywheel. Even a small misalignment can prevent the starter gear from engaging the flywheel correctly, leading to the pushing issue.
- Loose or Damaged Bolts: Ensure that the starter bolts are tight and secure. Loose bolts can cause the starter to shift out of alignment or move while engaging the flywheel, resulting in the starter pushing. Additionally, inspect the bolts for any damage or deformation.
- Failed Solenoid: The starter solenoid is responsible for engaging the starter gear with the flywheel. If the solenoid is faulty, it may not fully engage the gear, leading to the starter pushing the flywheel.
- Excessive Flywheel Wear: If the flywheel has excessive wear on its teeth or ring gear, it may not provide enough grip for the starter gear to engage properly. This can cause the starter to push the flywheel.
- Bent Flywheel: Check if the flywheel is bent or warped. A damaged flywheel can prevent the starter gear from meshing correctly, leading to the pushing issue.
Troubleshooting:
- Inspect Starter: Remove the starter and carefully examine it for any visible damage or issues. Pay attention to the starter gear, solenoid, and the mounting surface.
- Test Starter: Perform a starter test to ensure it's functioning correctly. Connect the battery and engage the starter. If the starter gear is not engaging or retracting properly, it's likely faulty and needs to be replaced.
- Check Alignment: Ensure that the starter is properly aligned with the flywheel. You can do this by using a straightedge or alignment tool to measure the distance between the starter gear and the flywheel ring gear. Adjust the starter's position if needed.
- Secure Bolts: Tighten the starter bolts to ensure the starter is securely mounted in place. Replace any damaged bolts.
- Inspect Flywheel: Check the flywheel for any damage, wear, or bending. If the flywheel is damaged, it will need to be resurfaced or replaced.
If you've gone through these steps and the problem persists, it's recommended to consult with a qualified mechanic for further diagnosis and repair.
