How to disconnect connecting rod and crank

In summary, disconnecting the connecting rod from the crankshaft requires a few steps that may vary depending on the type of engine. These include removing the engine, turning it upside down, removing the connecting rod cap bolts, and gently tapping the connecting rod to separate it from the crankshaft. Special tools, such as a socket wrench and rubber mallet, are necessary for this process. The purpose of disconnecting the connecting rod and crank is usually for engine repair or maintenance, and it is recommended to remove the engine for easier access. Safety precautions, such as ensuring the engine is cool and wearing protective gear, should also be taken.
