Clean the bearing holes with white silk before
assembly, then check the camshaft bushing hole
for scratches, dust or oil stains. Especially, do not
damage the inner hole of the camshaft bushing,
because the bushing will not be processed after
assembly. After the camshaft bushing is pressed
in, the bushing fuel hole and the cylinder fuel
passage hole shall coincide, and the camshaft
bushing shall be flush with the front end surface
of the cylinder block. If the camshaft bushing is
higher than the front end surface of the cylinder
block, it shall be reworked. The mating data of
camshaft bushing hole is -0.178 mm ~ -0.102 mm.
