BMW 5 Series: Chain track

BMW 5 Series G30 2016-2025 Training Manual / B58TU Engine / Engine Mechanical / Crankshaft drive / Chain track

Crankshaft drive
Comparison between chain track of B58 engine and B58TU engine

  1. Chain track, two-part timing chain drive B58 engine
  2. Chain track, single-part timing chain drive B58TU engine
  1. 6-cylinder engine
  2. Upper timing chain
  3. Timing chain
  4. Lower timing chain
  5. Drive chain, oil vacuum pump

The way the combined oil vacuum pump is driven via a separate drive chain from the crankshaft has not changed compared with the Bx8 engines. Only the change of the chain tracks has changed: The drive chain of the oil vacuum pump is now in front of the timing chain.

Dropping the second timing chain offers the following benefits:

  • Improved acoustics
  • Lower space requirement
  • Reduced weight

Chain tensioner

  1. Tensioning rail
  2. Sealing sleeve
  3. Chain tensioner with screw thread

Due to the cylinder head manufacturing process, the chain tensioner now has a sealing sleeve with a height of 12.5 mm instead of a sealing ring. The spring force of the chain tensioner lies between 40 Nm (extended) and 90 Nm (retracted).
