How do you remove the pulley from power steering pump on a 1997 Chevy blazer if it does not have bolt pulley?

A 1997 Chevy Blazer power steering pump pulley that doesn't have retaining bolts is likely a press-fit pulley. This means it's pressed onto the pump shaft. Removing it requires specialized tools and careful technique to avoid damaging the pump shaft or pulley. Here's how you generally approach it:

Tools You'll Need:

* Pulley puller: This is absolutely essential. You'll need a puller specifically designed for power steering pump pulleys. There are several types, including:

* Three-jaw puller: This is a common and versatile option.

* Power steering pump pulley puller: These are specifically designed to fit the shape of the pulley and minimize damage.

* Sockets and wrenches: You might need these to remove any retaining nuts or bolts that *might* be present (despite your statement that there are none, double-check), or for holding the pump stationary while you pull the pulley.

* Impact wrench (optional but recommended): This can make loosening any stubborn nuts much easier.

* Penetrating oil (like PB Blaster): Apply this generously to the pulley's shaft before attempting removal to help break any corrosion or rust. Let it soak for at least 30 minutes.

* Soft-jawed wrench or pliers: This is for added grip and to prevent damage to the pulley during removal.

* Clean rags or shop towels: To clean the area and catch any debris.

* A vise (potentially): This could be useful for holding the pump securely in place while you use the puller. Be cautious not to damage the pump.

Removal Procedure:

1. Safety First: Disconnect the battery's negative terminal. This is crucial for safety.

2. Prepare the Area: Work in a clean, well-lit area. Have all your tools ready before you begin.

3. Apply Penetrating Oil: Liberally spray penetrating oil on the area where the pulley meets the pump shaft. Let it soak for at least 30 minutes, ideally longer.

4. Secure the Pump: If possible, secure the power steering pump in a vise, ensuring it's stable and protected from damage. Use soft jaws or padding to protect the pump's housing.

5. Attach the Puller: Carefully position the pulley puller according to its instructions. Make sure the puller's jaws are evenly gripping the pulley.

6. Apply Pressure: Slowly and steadily apply pressure to the puller. Avoid sudden jerks or excessive force, as this could damage the pump shaft or pulley. Use a steady, controlled pressure.

7. Remove the Pulley: Once the pulley starts to move, continue applying pressure until it's completely removed.

8. Clean: Clean the pump shaft and pulley. Inspect both for any damage.

Important Considerations:

* Professional Help: If you're uncomfortable performing this task yourself, consider taking your vehicle to a qualified mechanic. Damage to the pump shaft can be costly to repair.

* Pulley Damage: There's always a risk of damaging the pulley during removal. If the pulley is severely rusted or seized, it might be damaged beyond repair.

* Pump Shaft Damage: Be extremely careful not to damage the pump shaft. This is the most critical part of the process.

Remember, if you're not comfortable working on your vehicle, a professional mechanic is the best option to prevent costly mistakes. They have the right tools and expertise to handle this task safely and efficiently.
