A defective crankshaft must be replaced. Some crank webs may be blue
coloured around the crankpin. This is, however, a normal result of the heat
treatment around the crankpin hole. Check the big end of the connecting rod.
Should there be seizure marks or discolored spots on the sides, the crankshaft
must be changed.
The connecting rod should not show any radial play (up and down). The axial
play should, however, be 1.2 – 1.6 mm.
