2002 BMW 6-Cylinder ENGINE (3.2 litre BMW M3) PRODUCTION. In the factory of the 2002 BMW M3, several critical stages of the engine assembly process take place. It begins with work on the engine block, lifted by a precision crane to be correctly positioned on the assembly line. Next, a precision machine engraves a serial number on the engine block to ensure traceability and quality control. The crankshaft is installed inside the block, using precision equipment for proper alignment.
The crankshaft is lubricated to ensure operation without friction, preventing premature wear. The installation of the pistons in the engine block requires careful inspection of the pistons’ quality and integrity. The valves are installed in the cylinder head, followed by the installation of the valve springs, essential for the proper functioning of the engine.
The final assembly of the cylinder head involves precise tightening of bolts to ensure proper alignment and securing of all components. The timing chain is installed to synchronize the camshaft’s movement with the crankshaft. The oil pump, crucial for circulating engine oil, is installed at the front of the engine.
The camshafts are checked and installed on the top of the engine, ensuring they are properly aligned and secured. Lubrication of the camshafts is essential to prevent wear and ensure efficient operation. Finally, a camshaft rotation test is performed to verify that it rotates freely and without obstructions, confirming correct installation and alignment.
