What to Do If the Crankshaft Bolt Is Too Tight?

[DelLilah]

The solutions for a crankshaft bolt that is too tight are: 1. Pour a little oil on the bolt and then turn it counterclockwise; 2. First heat the bolt with a conductive material, let it cool, and then turn it; 3. Dip a screwdriver in a little 502 glue, bond it to the bolt, and then turn it open; 4. Spray rust remover on the bolt to remove rust before loosening it. The crankshaft is an important component in the engine, bearing the force transmitted by the connecting rod and converting it into torque, which is output through the crankshaft to drive other engine accessories. The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertial forces, and reciprocating inertial forces, causing it to bear bending and torsional loads.
