OVERHAUL
1. REMOVE AIR CLEANER CAP SUB±ASSY
2. REMOVE VACUUM PUMP ASSY
(a) Disconnect the 2 vacuum hoses and oil hose from the
vacuum pump assy.
(b) Remove the 2 bolts and vacuum pump assy.
(c) Remove the 2 O±rings from the vacuum pump assy.
3. INSPECT VACUUM PUMP ASSY
(a) Turn the coupling counterclockwise direction by hand
when seeing from the coupling direction and check for
any abnormality such as dragging or torque fluctuation.
NOTICE:
Pay coupling attention, because the engine oil remained in
the pump escapes while coupling is turning.
4. REMOVE VACUUM PUMP UNION
(a) Using soft jaws on a vise, hold the vacuum pump assy in
a vise.
NOTICE:
Do not tighten the vise excessively and perform the work
while holding the vacuum pump assy by hand.
(b) Remove the union bolt, vacuum pump union and 2 gas-
kets.
5. REMOVE CHECK VALVE SUB±ASSY
(a) Remove the check valve sub±assy and gasket.

(h) Using soft jaws on the vise, hold the vacuum pump in the
vise.
NOTICE:
Do not tighten the vise to tightly.
(i) Tighten the 3 bolts.
Torque: 7.8 Nm (80 kgfcm, 69 in.lbf)
14. INSTALL CHECK VALVE SUB±ASSY
(a) Install the check valve sub±assy and a new gasket.
Torque: 74 Nm (750 kgfcm, 54 ftlbf)
15. INSTALL VACUUM PUMP UNION
(a) Install the vacuum pump union and 2 new gaskets with
the union bolt.
Torque: 14 Nm (140 kgfcm, 10 ftlbf)
HINT:
Align and insert the pin of the union into the matching hole of
the casing.
16. INSPECT VACUUM PUMP ASSY
(a) Turn the gear counterclockwise direction by hand when
seeing from the vacuum pump gear direction and check
for any abnormality such as dragging or torque fluctua-
tion.

17. INSTALL VACUUM PUMP ASSY
(a) Coat 2 new O±rings with engine oil, and install them to the
vacuum pump assy.
(b) Install the vacuum pump assy aligning the coupling with
the slit of the camshaft.
(c) Install the 2 bolts.
Torque: 21 Nm (214 kgfcm, 15 ftlbf)
(d) Connect 2 vacuum hoses and oil hose.
18. INSPECT CHECK VACUUM PUMP OPERATION
(a) Slide the clip, then disconnect the vacuum hose from vac-
uum pump assy.
(b) Connect the hose of the vacuum gauge to the vacuum
pump assy.
(c) Block off another hose of the vacuum gauge with the hose
clamp No.2.
(d) Start the engine and warm it up for more than 2 minutes.
(e) With the engine idle, check the negative pressure of the
vacuum pump assy.
Standard: More than 650 mmHg (86.7 kPa).
(f) Remove the vacuum gauge from the vacuum pump assy.
(g) Connect the vacuum hose with the clip to the vacuum
pump assy.
