Inspecting the crankshaft alignment

tricity of the surfaces of diam. «A»-«B»-« C» are
within 0.03 mm. (reading limit on the dial gauge);
in addition, check the eccentricity of diam. «D», for
which a maximum reading of 0.02 mm is permitted.
In the case where eccentricity is not much above
prescribed levels, straighten the shaft by acting
on the counterweights with a shim or tighten them
in a clamp (with an aluminium bushing) as re-
quired..
