Adjusting
1. Position crankshaft to 30° BTDC of cylinder 1 (arrow).
NOTE:
At 30° BTDC of cylinder 1 the camshafts can be rotated without the valves touching the piston crowns.
2. Remove chain tensioner (5). Refer to Timing Components - Timing Chain Tensioner - Service and Repair - Procedures - Removing and
Installing Chain Tensioner See: Timing Components/Timing Chain Tensioner/Service and Repair
3. Remove front cover (30) and top guide rail (42). Refer to Timing Components - Timing Cover - Service and Repair - Procedures See: Timing
Components/Timing Cover/Service and Repair
4. Unbolt exhaust camshaft sprocket (3).
5. Rotate camshafts with wrench (25) 119 589 00 01 00 (WAF 27) or 104 SB9 01 01 00 (WAF 29) until the 4 mm holes in the camshaft flanges are
touching top edge of cylinder head.
6. Insert pins (1) into holes (arrows).
7. Rotate crankshaft with wrench socket insert in direction of rotation of engine to TDC position of cylinder 1; raise timing chain for this step.
8. Rotate camshaft adjuster by hand in direction Of rotation of camshaft to "retarded" position stop.
9. Fit timing chain onto inlet camshaft sprocket and check whether timing chain is resting correctly against guide rail in timing case cover.
10. Install exhaust camshaft sprocket (3) in base position of camshaft.
11. Install front cover (30) and top guide rail (42). Refer to Timing Components - Timing Cover - Service and Repair - Procedures See: Timing
