chain guide as an assembly.
lLoosen mounting bolts in reverse order shown in figure.
lDo not remove any bolts not shown in figure. (Especially
never remove M6 bolts on vacuum pump.)
lUse seal cutter (special service tool) or other suitable tool to
remove.
INSTALLATION
1. Install vacuum pump and cylinder head rear cover assembly
onto cylinder head. Refer toEM-133, "
ASSEMBLY".
lApply Genuine Liquid Gasket or equivalent (Refer toEM-103,
"Precautions for Liquid Gasket".) to area shown in the figure.
lAttaching should be done with in 5 minutes after coating.
2. Tighten mounting bolts in order shown in the figure.
3. Install rear cam sprocket mounting bolts by fixing the hexagonal
portion of the camshaft. .

lAttaching should be done with in 5 minutes after coating.
CAUTION:
Never start engine with vacuum circuit being open. If
engine is started and vehicle is running while vacuum
pump is open (with vacuum hose disconnected), blow-by
flow rate will increase and engine may be damaged.
6. Install in reverse order of removal after this step.
lWhen vacuum hose is connected, insert it securely by at least
15 mm (0.59 in).
INSPECTION AFTER INSTALLATION
Check generated vacuum satisfies the specification at idle speed. Refer toEM-131, "INSPECTION BEFORE
REMOVAL".

toEM-103, "
Precautions for Liquid Gasket".
B: Miniimize the overlapping area of the bead, with start and end
areas of bead as shown in the figure.
Apply so that the portion marked * comes at an external loca-
tion but cannot be viewed externally after engine is assembled.
