Need the torque settings for the cylinder head :main bearings and big ends
CHECK BELOW..
Tightening torques
Bolted connections Tightening torque
Bolts, nuts M 6 10 Nm
M 8 20 Nm
M 10 45 Nm
M 12 60 Nm
Deviating from above
Exhaust pipe to manifold 40 Nm
Installation
Note
t Only remove the new cylinder head gasket from its packing immediately before installing.
t Handle the new gasket with extreme care. Damaging will lead to leaks.
- Place a clean cloth in cylinders so that no dirt or emery cloth particles can get in between cylinder wall and piston.
- Also prevent dirt and emery cloth particles from getting into the coolant.
- Carefully clean cylinder head and cylinder block sealing surfaces. Thereby ensuring that no scoring or scratches are formed (when using abrasive paper the grade must not be less than 100).
- Carefully remove metal particles, emery remains and cloths.
- Set No. 1 cylinder piston to TDC and then turn crankshaft back slightly.
- To centralize, screw guide pins from 3450/1 into front outer holes for cylinder head bolts-flechas-.
- Place the new cylinder head gasket in the centralizing pins -A-. Lettering (Part No.) must be readable.
- Fit cylinder head, screw in 8 remaining cylinder head bolts and tighten by hand.
- Remove the guide pins with tool 3450 by the bolt holes. To do this, turn the tool left until the pins are removed.
- Fit remaining cylinder head bolts and tighten hand-tight.
- Tighten cylinder head in tightening sequence as follows:
- Tighten all bolts to 30 Nm.
- Then tighten all bolts a 1//4 turn (90 °) further using a rigid wrench.
- Then tighten all bolts again a 1/4 turn (90 °) further.
Note
There is no requirement to retighten the cylinder head bolts after repairs.
The rest of the assembly is basically a reverse of the dismantling sequence.
Note
When the camshaft is turned, the crankshaft must not be at TDC. Danger of damage to valves or piston crowns.
