– Check the installation position for the balance shaft pipe -arrow-. The tab -arrow- must be at the top. It is an anti-twist mechanism.

Note

Press the pipe together slightly to position it in the installation po‐ sition. Insert the Wrench - Pin Type - 3212- into the front pipe openings and press together. Then insert the pipe with the Wrench - Pin Type - 3212- .

– Place the new balance shaft in a freezer for 30 minutes or spray it with commercially available cooling spray. – Lubricate the balance shaft bearing with engine oil. – Install the exhaust camshaft balance shaft.

– Before tightening the bolt -1- make sure the balance shaft lies level on the crankcase.

Note

If the balance shaft is not level, then the pipe for the balance shaft must be installed again.

– Install the drive chain for the balance shaft and the camshaft timing chain. Refer to ⇒ page 117 . Further assembly is performed the reverse order of the removal.

1.13 Valve Timing, Checking Special tools and workshop equipment required ♦ Dial Gauge - 0-10mm - VAS6079- ♦ Dial Gauge Adapter - T10170A- ♦ Caliper gauge – Remove the upper timing chain cover. Refer to ⇒ “1.3 Upper Timing Chain Cover, Removing and Installing”, page 91 . – Remove the right wheel and remove the right wheel housing liner. – Turn the crankshaft with the socket SW 24 on the vibration damper in the direction of the engine rotation until the mark‐ ings -arrows- are almost on top. – Remove the spark plug from cylinder 1.

– Install the Dial Gauge Adapter - T10170A- all the way into the spark plug thread. – Insert the Dial Gauge - 0-10mm - VAS6079- using the Exten‐ sion - T10170A- until stop and secure with the locking nut -arrow-. – Turn the crankshaft slowly in the direction of the engine rota‐ tion until the maximum dial reading is reached. When the maximum dial reading is reached (BDC of the meter) position the piston at »TDC«.

Note

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

– Measure the distance from the left outer edge -A- to the mark‐ ing -B- on the intake camshaft. • Specified value: 61 to 64 mm.

– Once the specified value is reached, measure the distance between the marking on the intake camshaft -B- and the mark‐ ing on the exhaust camshaft -C-. • Specified value: 124 to 126 mm.

Note

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

Note

♦ If the cylinder head bolt with the internal multi-point and collar is installed, the camshafts must be removed before removing the cylinder head bolt. ♦ Always replace self-locking nuts, bolts which have been tight‐ ened an additional turn as well as gaskets and seals. ♦ The plastic protectors installed to protect the open valves must only be removed immediately before mounting the cylinder head.
