3.1. Tools Required
- Power Steering Pulley Removal and Installation Tool Kit
- Wrenches (appropriate sizes for tool kit)
- Bench Vise
- Safety Glasses
- Gloves
3.2. Removal of Original Pulley
- Ensure all necessary tools and parts are readily available.
- Mount the power steering pump loosely in a bench vise. Do not clamp tightly on the body of the power steering pump, as this can damage the internal precision gears.
- Select the appropriate pieces from your pulley removal tool kit based on your specific application.
- Note the exact position of the original pulley on the pump shaft before removal. This will help ensure the new pulley is installed to the correct depth.
- Assemble the removal tool onto the pulley.
- Remove the pulley by turning the hex on the threaded shaft of the removal tool clockwise. Continue turning until the pulley is fully removed from the pump shaft.
3.3. Installation of New Pulley
- Select the appropriate pieces from your pulley installation tool kit based on your specific application.
- Set the new Dorman 300-006 pulley onto the pump shaft with the hub facing up.
- Assemble the installation tool.
- Thread the installation tool into the pump shaft.
- Turn the installation nut clockwise while simultaneously rotating the threaded shaft counter-clockwise.
- Continue this process until the new pulley is seated to the same depth as the original pulley. Caution: It is possible to install the pulley too far. Check your progress several times during the installation process to prevent over-pressing the pulley onto the shaft.
- Once the pulley is seated to the proper depth, remove the installation tool from the pump and pulley assembly.

4. Operation
After successful installation, the Dorman 300-006 Power Steering Pump Pulley facilitates the transfer of power from the engine's accessory drive belt to the power steering pump. This ensures the pump operates correctly, providing hydraulic pressure for assisted steering. Proper operation is indicated by smooth and responsive steering, without unusual noises or excessive effort.
5. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your power steering system and its components.
- Periodically inspect the power steering belt for signs of wear, cracking, or fraying. Replace as needed.
- Check the power steering fluid level and condition regularly. Top off or replace fluid according to your vehicle manufacturer's recommendations.
- Listen for any unusual noises (e.g., squealing, grinding) coming from the power steering pump or pulley area, which could indicate a problem.
- Inspect the pulley for any signs of damage, wobbling, or misalignment.
- Keep the engine bay clean to prevent dirt and debris from accumulating on the pulley and belt.
6. Troubleshooting
If you experience issues after installing the Dorman 300-006 Power Steering Pump Pulley, consider the following common troubleshooting steps:
- Squealing Noise: This often indicates a loose or worn serpentine belt. Check belt tension and condition. It could also be a misaligned pulley.
- Hard Steering: Check power steering fluid level. Inspect for leaks in the power steering system. Ensure the belt is properly tensioned and not slipping.
- Wobbling Pulley: Re-check the pulley installation depth. Ensure the pulley is fully seated and the installation tool was used correctly. A wobbling pulley can indicate improper installation or a damaged pump shaft.
- Unusual Grinding/Whining: This may point to an issue with the power steering pump itself, or a bearing within the pulley. Professional diagnosis may be required.
If troubleshooting steps do not resolve the issue, it is recommended to consult a certified automotive technician.
