Working Instructions

CAUTION: Pay attention on Engine 271 that it can only be worked on in the specified work tolerance.

1 Inspect flatness of crankcase contact surface in longitudinal direction
2 Face-grind crankcase together with timing case cover

NOTE: Only machine cylinder head contact surface if porous or damaged points are present or if an impermissible variation of the flatness in the longitudinal direction is measured.

3 NOTE: Engine 111: The stock removal at cylinder head and at crankcase of an engine must be no more than max. 0.4 mm.
