How to Remove Crankshaft Pulley Without Puller?

Now, get ready! You’ll need a socket set, an impact wrench, and a crankshaft pulley remover. Safety first! Don’t forget protective gear like glasses and gloves. Got everything? Let’s prep for crankshaft pulley removal!


Gather the tools you need

To remove the crankshaft pulley, you’ll need certain items. Ensure that the engine’s cool and safety precautions are taken first. The tools required for the project include:

  • An adjustable wrench
  • A force like a hammer/a chisel or an impact gun
  • A puller fit for your engine
  • Socket wrenches (6mm, 10mm, 12mm) depending on your engine specs
  • Grease lubricant or assembly lube
  • A screwdriver

It’s important to have all these tools before starting. If the task is too hard or complex, get help from a certified mechanic with experience in vehicle repairs.

Disconnect the battery

Before beginning, ensure the car’s battery is disconnected. Safety first! Open the hood to find it, and then detach the cables from the terminals. Utilize a wrench or pliers if needed. Put the cables away from your workspace in a secure spot.

Drain the coolant

Start by draining the coolant from the engine. After that, unplug the battery terminal and ground cable. Next, take out the intake manifold and other pieces blocking access to the crank pulley for the improved angle of removal. If needed, take away any brackets or hoses connected to the crank pulley for more space.

Utilize a socket wrench with an appropriate size socket for the crankshaft bolt size of your vehicle. Apply constant pressure as you turn counterclockwise with the socket wrench while keeping the breaker bar steady against a floor or wall. Caution: if it is an automated transmission, do not use too much force on the crankshaft bolt, as it could break. If needed, switch out the ratchet with an impact wrench to easily loosen the bolt.

Removing the Crankshaft Pulley

The crankshaft pulley is a vital part of the engine. It drives accessories like the alternator, water pump, and power steering pump. But, how can you remove it without a puller? That’s possible, but it’s complicated and takes time.

Here, we’ll discuss the advantages and disadvantages of removing a crankshaft pulley without a puller:

Remove the fan belt

The first step to remove the crankshaft pulley is to loosen the fan belt. This is usually done by releasing the tension. Pull it off the pulley. Then, loosen and remove the bolts or screws holding it onto the crankshaft. After this step, it should be possible to extract the pulley.

Be aware that this process may vary for different engines or car makes. To stay safe and protect the vehicle, use a quality torque wrench when removing the nuts and bolts. This will help prevent any further issues or damage from over-torquing or under-torquing of essential components.

Remove the bolts that secure the crankshaft pulley

Sometimes, automotive repairs require removing the crankshaft pulley. This includes replacing the serpentine belt, timing belt, and seals. But, if the engine has tight spaces, it can be challenging to use a puller tool.

Here is how to remove a crankshaft pulley without a puller:

  1. Disconnect the car battery’s negative lead for safety.
  2. Locate the bolts of the crankshaft pulley. Consult the manual for the number of bolts and torque specifications.
  3. Loosen the bolts with an appropriate hand wrench or breaker bar. Rotate the crankshaft counterclockwise. Don’t turn more than two full revolutions.
  4. If needed, disengage the clips or other attachments.
  5. Tap around loose anchors until the crankshaft pulley comes off. Also, remove all components that were originally installed.

Use a puller to remove the crankshaft pulley

A puller is a best and safest tool to use when removing crankshaft pulleys from an engine. A 2-jaw puller or a 2-Jaw Gear Puller can be used, depending on the access. It is best to have both tools available.

When using a 2-jaw puller, check for any cracks or deformities. Do not insert the jaws into these areas as they will become larger. Ensure all jaws make contact with undamaged surfaces.

When using a 2-Jaw Gear Puller, there are two arms with hooks. They draw out parts held in place by thread-locking methods or corrosion. Turn the wingnut handle gently and evenly until you feel resistance. Ensure all components are released before removing them. Use a secure holder device, like pliers, for added grip strength when needed.

Replacing the Crankshaft Pulley

Replacing the crankshaft pulley is common. It requires a few special tools. But, don’t worry! It’s not hard to do. You don’t even need a puller. As long as you’re ready and have the right tools, you’re all set.

This article will show you how to replace the crankshaft pulley without using a puller:

Clean the crankshaft pulley

To remove the crankshaft pulley, it must first be cleaned. Use a wire brush and degreaser or engine cleaner to get into all the crevices. Additionally, check the mounting surface of the crankshaft. Make sure it is also free of debris. This will guarantee that when you replace the pulley, it fits properly.

Inspect for any warped or broken parts on both surfaces. These could cause improper placement.

Install the new crankshaft pulley

Installing a crankshaft pulley is easy. Gather the right tools and raise the car with a lift or other system. Secure the car so it won’t move.

  • Put the new crankshaft pulley in place. Align the keyway with the belt drive system. Use bolts to secure. Spin it with your fingers to make sure it runs smoothly.
  • Reinstall the belt drive system and replace any parts taken out during installation.

Reinstall the fan belt

First, unbolt and replace the crankshaft pulley. Then, install and tension the fan belt. Route it properly and make sure it’s seated on each pulley. No twists or blockages! Look at a diagram or the vehicle’s manual if you can.

Tension the belt according to manufacturer specifications or what your car’s manual says. Look for arrows or marks that guide proper tensioning. If there aren’t any, use a “fish scale” or torque wrench to measure the force. Too much tension can damage bearings, and too little slack can cause noise and component failure.

Finishing Up

Finally, take off all the bolts and nuts. Next, to remove the crankshaft pulley, you don’t need a pulley puller. Here are two methods on how to do it without one:

Refill the coolant

Finish off any other tasks, for example, refilling the coolant, or installing new gaskets. Before refilling the coolant, flush the cooling system to get rid of any particles that may have stuck. After the gaskets are installed and all hoses connected, fill the reservoir with a 50/50 mix of antifreeze and water.

Once done, start the car to check for any leaks and to make sure it’s working fine. If you have doubts about your work, take your car to a qualified mechanic for assessment.

Reconnect the battery

Before connecting the battery again, ensure all disconnected plugs and leads go back to their right spots. Start by attaching the negative (black) lead first, making sure it’s firmly fixed and won’t become loose from vibration or touching other components. Then attach the positive (red) lead. Check that it’s securely in place on its post.

Reconnecting the car battery usually resets any computer systems on board, so you may require:

  • Reprogramming select settings
  • A scan for errors after you start the vehicle.

Test the engine

Before beginning the crankshaft removal process, it is important to test the engine. Start by checking the oil level and topping it off, if needed.

Next, turn on the engine and listen for any strange sounds or vibrations. Stop the engine right away if you hear something off.

Also, visually inspect to ensure all components are securely attached to their mounts. Check for worn belts or hoses that may need replacing.

Inspect all bolts holding down items near the crank pulley, including those from underneath. You may need a mirror tool for this. Ensure they are correctly tightened, as loose ones can be unsafe.
