Timing Case

The following components are attached to the timing case of the X 10 XE engine:

• Front view
• Rear view (inside, lower part)

• Camshaft sensor

• Oil pressure regulating valve
• Service aperture for chain tensioner

The individual components are described in detail in the following sections.

5.2.2 Timing Case

Timing Chain

The two camshafts are driven by a simplex timing chain powered by the crankshaft. The correct chain tension is provided by a spring-assisted, hydraulic, maintenance-free chain tensioner. The timing chain is guided by a tension rail and an additional guide rail. A sliding rail guides the chain between the camshaft sprockets. With the exception of the upper section (camshaft sprockets), the chain drive is accommodated completely in the timing case.
