Checking the valve timing

Rotate crankshaft 2 turns in direction of engine rotation. Screw locking bolt -T10340- into cylinder block as far as it will go and tighten to 30 Nm. Turn the crankshaft in the direction of engine rotation until it stops. The counterweight of the crankshaft is now adjacent to the locking bolt.

Note: The locking bolt - T10340- only locks the crankshaft in the working direction of rotation.

The camshaft clamp -T10494- must be easy to install. The camshaft lock must not be installed with an impact tool. Insert locking pin -T10494- into camshafts as far as stop and hand-tighten screw -arrow-. If the camshaft lock -110494- cannot be inserted, the valve timing is incorrect: Re-adjust the valve timing. If the camshaft clamp -T10494- is inserted, the valve timing is correct. Unscrew locking bolt -T10340-. Unscrew bolt -arrow- and remove camshaft clamp -T10494-. Tighten screws -1- and -2- to final torque. Use stop -T10172- with adapters -T10172/1- for this. Tighten screw plug -1- using stop -T10172- with adapters -T10172/1-.

Carefully! Risk of engine damage. After finishing work, check that locking pin -T10340- and camshaft clamp -T10504- have been removed from engine.

Installation in reverse order.
