Installing (adjusting valve timing)

Note:

The position of the toothed belt must be set as
described below, even after repairs in which the
belt is only taken off the camshaft sprocket.
When turning the camshaft, the crankshaft must
not be at TDC at any cylinder. There is a
danger of damage to valves/piston crown.

- Align marking on camshaft sprocket with marking at cylinder head
cover.
- Place toothed belt on crankshaft sprocket (observe direction of
rotation).
- Install toothed belt guard - lower part.
- Secure vibration damper/belt pulley with one bolt (note installation
arrangement).
- Set crankshaft to TDC for cylinder No. 1.
- Install toothed belt onto coolant pump, then tensioning roller, and finally
camshaft sprocket.
