How do you Remove and refit a camshaft?

To remove a camshaft, first disconnect the battery and drain the engine oil. Then, remove any components obstructing access, such as the timing belt or chain, and unbolt the camshaft from its housing. Carefully lift it out, ensuring not to damage any surrounding parts. To refit, reverse the process: place the camshaft back in position, secure it with bolts, and reassemble any components that were removed, making sure to follow the manufacturer's specifications for torque settings.
