Another method is using a 3-jaw puller to remove the flywheel. But remember to use a proper flywheel puller according to your chainsaw engine and flywheel specifications for a safe removal process. 

Precautions Before Removing a Chainsaw Flywheel

Before attempting to remove a chainsaw flywheel, one should take several precautions to ensure the safety of themselves and others.

One should always make sure that the chainsaw is unplugged or turned off before making any attempt at removal.

Additionally, it is important to wear protective clothing such as gloves and eye protection while handling any parts of a chainsaw as they can be sharp and cause serious injury if mishandled. The work area should also be well-ventilated in order to prevent exposure to harmful fumes from the fuel tank. In addition, all screws and bolts should be loosened with an appropriate wrench or other tool so that they don’t become stripped in the process of trying to remove them.

Flywheel Removal Techniques

Flywheel removal techniques can vary depending on the type of engine and flywheel you are using. For example, small engines may require the use of a screwdriver to loosen the bolts that secure the flywheel to the crankshaft. However, larger engines may require more specialized tools to remove the flywheel.

In some cases, it might be necessary to use an impact wrench or hydraulic jack to loosen and remove heavy flywheels from large diesel-powered vehicles. On these types of vehicles, there must also be careful attention paid to properly aligning everything before installation so that proper torque can be applied when tightening down components after installation is complete.

Using a 3-Jaw Flywheel Removal Tool 

Using a 3-Jaw Flywheel Removal Tool is one of the easiest and most efficient ways to remove a flywheel from an engine. It requires minimal effort and can be done quickly without taking apart other components of the engine. Here are the steps for using this tool:

1. Secure the flywheel in the tool

Position the flywheel into the three jaws of the removal tool, making sure that it is evenly balanced and centered within the jaws. Tighten each jaw with an adjustable wrench until they are firmly secured to the flywheel.

2. Apply pressure to loosen the flywheel

With an adjustable wrench or ratchet, apply pressure to one end of the tool’s handle while pushing down on the opposite end until there is resistance and you feel some movement from the flywheel.

3. Gradually increase pressure 

Continue applying pressure to both ends of the handle in a slow and steady manner until the flywheel has been completely removed from its mount.

4. Remove and inspect the flywheel

Carefully remove the flywheel from the removal tool and set aside for further inspection or replacement. Inspect it for any signs of wear or damage that may have occurred during removal and replace as necessary. Be sure to also inspect the mounting surface of the engine block for any residual dirt, debris, or corrosion before reattaching a new flywheel.

5. Clean up after your work

Before disposing of any parts, make sure to clean off any dirt or debris that may have collected during the process of removing the flywheel. Be sure to safely store all tools and parts so they can be used at a later date if needed.

6. Reattach the flywheel 

Once everything is inspected and cleaned, you can begin to reattach the flywheel by carefully placing it back in its original mount using an adjustable wrench or ratchet. Make sure that it is evenly balanced and centered within the jaws before tightening each jaw securely with a wrench. Finally, test for proper mounting by rotating the tool’s handle clockwise and counterclockwise a few times. If there is no resistance or difficulty in movement, the flywheel should be properly reattached.

7. Dispose of old parts

Finally, dispose of any old parts that were removed during the process of replacing the flywheel in an environmentally friendly manner.

8. Ensure Cleaning

Now its time to clean the parts with all other equipments and then go for the next step which is testing.

9. Test for proper mounting

Once everything is reattached, test for proper mounting by rotating the tool’s handle clockwise and counterclockwise a few times. If there is no resistance or difficulty in movement, the flywheel should be properly installed and ready for use!

Using a 2-Bolt Flywheel Puller

Using a 2 Bolt Flywheel Puller Removal Tool is one of the easiest and most efficient ways to remove a flywheel from an engine.

1. Prepare the Vehicle

Ensure the vehicle is in park or neutral, with the parking brake engaged and all spark plugs disconnected from the engine. Place blocks behind the rear wheels to prevent rolling.

2. Thread Bolts Into Block

 Insert two 1/2″-inch bolts into holes in either side of the block, leaving about 3/4″ protruding from each side. If necessary, rotate crankshaft to align these holes with flywheel puller bolts on crankcase cover plate.

5. Remove Flywheel

Once sufficiently loose, remove all attaching hardware and lift the flywheel from the engine block.

6. Clean and Inspect Flywheel

Clean the flywheel of all debris, dust, and dirt. Examine for any signs of wear or damage such as cracks, corrosion, or missing teeth. If necessary, replace the flywheel before reattaching it to the engine block.

7. Reattach Flywheel

When ready to reinstall the flywheel onto the engine block, lubricate its surface with a light oil.Place back over two bolts protruding from block and secure firmly with nuts and washers provided by manufacturer’s instructions.

8. Test Repair

Start vehicle and test for normal operation before driving. If all goes well, then the 2-bolt flywheel puller repair was successful.If not, then you may need to repeat steps or seek professional help.
