5) Measuring the Outside Diameters of the Cam Shaft
Measure the outside diameters of the cam shaft with a
micrometer. Calculate the oil clearance from the mea-
sured cam shaft outside diameter and the cam shaft
bush inside diameter measured with a cylinder gauge
after inserting the cam shaft bush into the cylinder block.
6) Extracting the Cam Shaft Bush
Extract the bush with a cam shaft bush tool.

1) Side Gap Around the Crank Shaft
Before extracting the crank shaft and when installing it,
contact a dial gauge with the end of the crank shaft.
Press the crank shaft to each of the right and left sides in
the axial direction to measure the side gap. Alternatively,
insert a thickness gauge directly into the clearance
between the thrust metal in the reference part and the
thrust face of crank shaft to measure the side gap. If the
measured value exceeds the wear limit, replace the
thrust metal with a new one.
