Timing Components: Adjustments

Valve Timing, Checking

Special tools, testers and auxiliary items required

• Dial Gauge 0-10 mm (VAS 6079)

• Dial Gauge Adapter (T10170) or (T10170 A)

• Caliper Gauge

- Remove the upper timing chain cover. Refer to => [ Upper Timing Chain Cover ] Upper Timing Chain Cover.

- Rotate the crankshaft from above, using the vibration damper bolt and the socket SW 24, in engine rotation direction until the marks - arrows - are almost on top.






- Remove the spark plug from cylinder 1.

- Install the dial gauge adapter (T10170/A) all the way into the spark plug threads.






- Insert the dial gauge 0-10 mm (VAS 6079) with the extending piece (T10170A/1) all the way and secure it with the locking nut - arrow -.

- Rotate the crankshaft slowly to the maximum dial reading in engine rotation direction. When the maximum dial reading is reached (Bottom Dead Center (BDC) of the gauge) the piston is at TDC.

• If the crankshaft was turned past TDC, turn the crankshaft two more turns in engine rotation direction. Do not turn the engine in the opposite direction of engine rotation.

- Measure the distance from the left outer edge - A - to the mark - B - on the intake camshaft.






• Specified value: 61 to 64 mm.

- Once the specified value is reached, measure the distance between the mark on the intake camshaft - B - and the mark on the exhaust camshaft - C -.






• Specified value: 124 to 126 mm

• If one tooth has an offset, there will be a deviation of approximately 6 mm from the specified value. Install the timing chain once again if there is an offset.
