about one turn.
(2) Loosen the shorter rocker bracket bolts first.
(3) Then, loosen the longer rocker bracket bolts.
(4) Remove the rokcer bracket bolts, and remove the
rocker shaft assembly from the cylinder head.
(5) Remove push rods.

1.2 Disassembling rocker shaft assembly

Disassemble the rocker shaft assembly.
Note: Be sure to arrange the parts in order during
disassembly. Keep the original combination of rocker
arm and shaft assembly, and when reassembling,
make sure to install them in their original positions to
restore the same clearance between the rocker shaft
and arms.
Do not remove the rocker bushing unless it is
defective or its inside diameter exceeds the limit.

When removing the cylinder head gasket, be careful
not to damage the cylinder head or crankcase surface
by tools such as a screwdriver.
(1) Remove the cylinder head bolt.
(2) Remove the cylinder head assembly by lifting it up.
Note: If the cylinder head assembly cannot be removed due
to crimping of the cylinder head gasket, tap the thick
area on the side of the cylinder head using a plastic
hammer to give a shock.
(3) Remove the gasket from the cylinder head.
Note: If there is a cylinder head problem, check the bolts for
tightness with a torque wrench before removing the
cylinder head bolts.
