  • Chain drive at the side of the engine emitting the forces
  • Single-part chain drive for driving the camshafts
  • Single sleeve-type chain 8 mm
  • Electric motor of the combined oil-vacuum pump via a separate chain
  • Plastic tensioning and guide rail
  • Hydraulic chain tensioner with spring preload and sealing sleeve.

The main difference between the chain drive compared with the B58 engine is the move from a two- part timing chain drive to a single-part timing chain drive. Deflection via the intermediate shaft on the top timing chain and the second timing chain is no longer needed. The chains used here are 8 mm sleeve-type chains. Because the intermediate gearing is no longer needed, the number of teeth on the crankshaft (23 teeth) and the VANOS adjuster (46 teeth each) has also changed.
