Camshaft Timing Chain

Camshaft Timing Chain


- Set crankshaft to TDC mark by turning crankshaft on vibration damper screw in direction of engine rotation - arrow -.







- First install intake side camshaft adjuster:







• The "24E" marking - 1 - and the tooth behind it must align with notch - 2 - in control housing. Markings on control housing => [ Markings on Control Housing with MPI Engines ] Timing Chain Component Overview.






- Turn sensor wheel - 1 - in camshaft adjuster clockwise - arrow - to stop.

• Camshaft bar (T10068 A) must not be used as counterhold.

- Hand tighten intake side camshaft adjuster in this position to intake camshaft.

• Contact surface of sensor wheel at screw head must be dry when installing.
- Lay camshaft timing chain in this position tightly against intake side camshaft adjuster sprocket.

- Starting with the toothed that has the "24E" marking, count exactly 16 rollers to the right on the timing chain. Mark this roller with a color marker.






• Exhaust camshaft adjuster is locked in the rest state. Therefore sensor wheel cannot be rotated when adjusting the valve timing. If locking mechanism is in rest state is not engaged (locked) turn adjuster in both directions by hand until it locks. If that is not possible, replaced camshaft adjuster.

- Now insert exhaust camshaft adjuster "32A" with tooth at arrow marking - 1 - into camshaft roller chain so that the exact, previously counted 16 rollers lie between marking "24E" and "32A" and markings - 1 - and - 2 - align.
