- Loosen the four head bolts (10) using a 12 mm socket wrench. Mark each
bolt with its position to avoid confusing them on assembly (three bolts are
112.5 mm long, one (10A) is 104.5 mm long).
- Remove the cylinder head (11) and its gasket (12).
Be careful not to lose the locating pins positioned between head
and cylinder.
Valve removal
- Remove the four valve buckets (1) and the shims (2). Mark them with their
positions to ensure correct assembly in the original position.
