BMW M3 and M4 Engine Repair Greensboro
The 'Crank Hub Issue' affects the 3-liter S55 engine found in the F8x BMW M3 and M4, and the M2 Competition models. The issue affects both tuned cars and those that have remained completely in stock with a full BMW service history.
So what is the Crank Hub issue?
In conventional engines the crankshaft spins the camshaft(s) connected to the valves via a belt or chain. The gears are secured by a keyway, ensuring that the connection between the pistons and valves remains constant. This is referred to as the engine's 'timing.' To keep all components in working order, BMW repair Greensboro is worth considering.
The timing gear can spin independently from the crank due to the initial defect in the design. Rough running and camshaft angle deviation problems are common symptoms. To avoid slippage, the crank hub employs OEM gears and is machined and pinned. Metallurgy outperforms the majority of aftermarket sprockets.
Solution for BMW M2 M3 M4 Crank Hub Issue
The S55 engine isn't built to handle much more boost than what the manufacturer recommends. The timing chain sprocket is known to spin on the end of the crankshaft due to the design of the crankshaft, causing the cams to go out of time.
The high-performance engine can withstand very high outputs by anchoring the cam sprocket to the crankshaft if you're expecting a huge power boost with bigger turbos. Seek professional BMW service for successful installation of the system. This is not something you should try at home.
