|---|---|---|---|
| inlet valve | before top dead centre (BTDC) | -8° | -8° |

Valve clearances when cold
The practical valve clearance when cold is obtained using shims of different thicknesses placed between the follower and the camshaft
- Inlet valve: 0,50 ± 0,05 mm
- Exhaust valve: 0,50 ± 0,05 mm
Cylinder head tightening
WarningOrder of tightening: bolt by bolt in the order from 1 to 22. loosening sequence: perform in reverse order (from 22 to 1)
Tightening procedure
- Pre-tighten to 6 daNm
- Angular tightening to 180°
