Note:
Crank web deflection first of all is a criterion of the alignment of the engine with the
shafting.
Heavy crank web deflection imposes additional loads on crankshaft and main bearings.
This means that the admissible deflection is determined by the engine load. A high load
admits less deflection than a low one.
The values below must be observed, if it is impossible to obtain the admissible limits for
the plant from MaK.
Only the values measured on an engine at operating temperature has to be used for
assessment. Values from a cold engine are of inferior importance.
Values for crank web deection:
Cylinder 1 : - 0,09 mm
other cylinders : 0,04 / - 0,06 mm
