*Fig. 9-4-9 shows an example of the methods to measure the side clearance of the crank-
shaft. In this case, it is measured by measuring the clearance between the pro- cessing face of the crankcase and adjusting color. As the packing is installed on the processing face of the crankcase, determine the clearance by taking into consideration the thickness of this packing which is 0.22 mm.
