Steps 3) to 7) of “Removal” in “Camshaft, Tappet and
Shim Removal and Installation: ”.
7) Loosen cylinder head bolts in such order as
indicated in the figure by using a 12 corner socket
wrenches and remove them.
NOTE:
• Don’t forget to remove bolt (M8) (1) as
shown in the figure.
• Never reuse cylinder head bolts once
disassembled it due to plastic deformation
tightening. Be sure to use new cylinder

to 40 N
˜
m (4.0 kg-m, 29.0 lb-ft).
c) Turn all bolts 60
q
according to numerical order in
the figure.
