Removing the crankshaft pulley bolt on a Honda can be a challenging task as it is often tightened to a high torque specification. Here is a general procedure to remove the crankshaft pulley bolt:
Preparation: Ensure that the vehicle is securely supported on jack stands or a lift, and the engine is turned off.
Access the Crankshaft Pulley: Remove any components blocking access to the crankshaft pulley, such as the engine undercovers or belts.
Lock the Crankshaft: To prevent the engine from rotating while removing the crankshaft pulley bolt, you can use a flywheel locking tool or insert a large screwdriver or pry bar into the flywheel teeth through the starter motor opening.
Use a Breaker Bar or Impact Wrench: Due to the high torque applied to the crankshaft pulley bolt, it is recommended to use a long breaker bar or an impact wrench to provide sufficient leverage. Attach the appropriate socket to the breaker bar or impact wrench.
Loosening the Bolt: Apply force in the counterclockwise direction (left-hand thread) to loosen the crankshaft pulley bolt. It may require a significant amount of force, and the use of a cheater bar or a pipe extension on the breaker bar can provide extra leverage if needed.
Special Tools: In some cases, a specialized tool such as a crankshaft pulley removal tool or a harmonic balancer puller may be necessary to remove the pulley after loosening the bolt. These tools can help separate the pulley from the crankshaft.
It's important to consult the specific service manual for your Honda model to understand any model-specific procedures or requirements for removing the crankshaft pulley bolt. Additionally, exercise caution and follow proper safety practices while working on your vehicle.
If you're unsure or uncomfortable performing this task yourself, it's recommended to seek assistance from a professional mechanic or a Honda dealership to ensure the job is done safely and correctly.
