Cylinder Head Assembly: Specifications

Cylinder Head

^ Install cylinder head and hand tighten all 10 new cylinder head bolts.
^ Tighten cylinder head in four stages in sequence shown as follows:
Tighten initially with torque wrench:
Stage I 40 Nm
Stage II 60 Nm
Turn further with rigid wrench:
Stage III = 1/4 turn (90°)
Stage IV = 1/4 turn (90°)

Note: Re-torquing the cylinder head after repairs is no longer necessary.

^ After tightening cylinder head, turn camshaft so that cam lobes for No. 1 cylinder point equally upward. Before installing toothed belt, turn crankshaft in direction of engine rotation to TDC.

Camshaft Bearing Caps
Tighten bearing caps 2 and 4 alternately and diagonally to 8 Nm + 1/4 turn (90°) further.
install bearing caps 5, 1 and 3 and also tighten to 8 Nm + 1/4 turn (90°) further.





^ Position straight edge diagonally over sealing surface (a check in opposite direction must also be made) and determine distortion with feeler gauges.
Max. permissible distortion 0.1 mm

Camshaft pulley securing bolts to 25 Nm
