–  Loosen socket head bolts in the sequence given and then remove completely. –  Carefully remove cylinder head.

Installing Installation is carried out in the reverse sequence; note the following: Tightening torque of the non-return valve -arrow-: 7 Nm Premise l  Pistons must not be at TDC.   Note t  Do not remove the new cylinder head gasket from its packing until immediately before its installation. t  Handle the new gasket with extreme care. If damaged, leaks may result. –  Place a clean cloth in cylinders so that no dirt or particles can get in between cylinder wall and piston. –  Carefully clean the sealing surfaces on the cylinder head and cylinder block. Ensure no long grooves or scratches are produced (if using sandpaper, it must be at least 100 grit). –  Carefully remove any abrasive metal particles and then the cloths. –  Position the cylinder number 1 into TDC and then rotate the crankshaft a little backwards. –  Fit a new cylinder head gasket. The lettering (spare part no.) must be legible. –  Fit cylinder head. Note the centering pins of the engine block. –  Fit new cylinder head bolts and tighten by hand.

–  Tighten cylinder head bolts in tightening sequence as follows: –  Tighten all bolts to 40 Nm. –  Then rotate all bolts at 90° using a rigid wrench. –  Finally, rotate all bolts one more time at 90°. –  Install support elements in cylinder head and fit respective roller rocker fingers onto respective valve stem end and support elements.
