* 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.

guide and valve stem is too large, re-
place the valve guide with a new one

While replace@, pull out the valve guide by
using a pull block and a pull bolt and then
