To save space, the oil pump has been modified by means of an additional weight on crankshaft. The pump has a recess (arrow) on housing shaft, to pro­vide enough distance between crankshaft and oil pump.

When changing the oil pump, check whether a crank­shaft with additional weight is installed. If yes, install only modified oil pump, part no. 110 180 33 01 for injection engines or 110 180 32 01 for carburetor engines with recess in housing shaft.
