What to Do If the Crankshaft Pulley Bolt Is Too Tight?

[AlexDella]

There is threadlocker inside the crankshaft pulley fixing bolt. When removing it, first secure the flywheel with a special tool, then clean the threadlocker with a cleaning agent during removal, and slowly take it off. Below is an introduction to the steps for removing the crankshaft bolt: Introduction: Generally, there is a spare threaded hole on the lower side of the cylinder block, near the first cylinder, which is usually sealed with a plug. Professional Removal Method: When removing the engine crankshaft pulley, first remove the plug. Rotate the engine until the first cylinder reaches top dead center, then use a special tool (similar to a long bolt, but only the part near the bolt head is threaded) to screw into the threaded hole. Use it to press against the balance weight of the first cylinder's crankshaft, preventing the crankshaft from turning. Then, use a large torque wrench to remove the pulley bolt. Non-Professional Removal Method: Use a large two-jaw puller to grip the pulley, then remove it with a torque wrench. This requires two people to cooperate but can easily damage the pulley.
