INFORMATION ON CYLIND ER HEAD CONTACT SURFACE - AH01.30-P-1000-05A
Engine 112, 113
The cylinder head contact surface mu st only be machined if mechanically damaged points are present.
The cylinder head contact surface must not be re-worked (face-ground) if a variation exists in the flatness of the
cylinder head contact surface in the longitudinal direction and transverse direction (distortion).
When the cylinder head is fitted on again, the distor tion is compensated for by tightening the cylinder head
bolts.
Stock removal on the cylinder head and at the crankcase of an engine must together be not more than 0.3 mm.
The valve seats must be re-set if the cy linder head separating surface is machined.
INFORMATION FOR ASSIGNING THE CYLIND ER HEAD GASKETS - AH01.30-P-1000-06V
Engines 112, 113
The assignment of the applicable cylinder head gasket on the left and right to the matching engine can be
verified when the cylinder heads are installed at the visible round notch between cylinder head and front of
crankcase.
Incorrectly installed cylinder head gaskets, e.g. with marking B instead of A, cause a knocking engine noise,
particularly at high idling speeds, as the pistons touch the projecting cylinder head gasket. If a complaint exists,
replace cylinder head gasket.
