Timing gear
Camshaft
"d": short camshaft with or without paint mark
Valve timing chart
Measurement with a theoretical valve play of 0,8 mm (timing check)
| before top dead centre (BTDC) | 4 °C |
|---|---|
| after bottom dead centre (ABDC) | 35 °C |
| before bottom dead centre (BBDC) | 43 °C |
| after top dead centre (ATDC) | 0 °C |
The valve clearance cold is obtained by shims of different thicknesses placed between the tappet and the valve stem
- Inlet valve 0,15 mm
- Exhaust valve 0,30 mm
