LUBRICATION

Engine Oil

3. Engine Oil

A: INSPECTION

1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the oil level gauge all the way. Be sure
that the oil level gauge is correctly inserted and
properly orientated.
4) Remove the oil level gauge again and check the
engine oil level. If the engine oil level is below the
“L” line, add oil to bring the level up to the “F” line.
5) After turning off the engine, wait a few minutes
for the oil to return to the oil pan before checking
the level.

NOTE:
To prevent overfilling of engine oil, do not add oil
above the “F” line when the engine is cold.

B: REPLACEMENT

1) Open the engine oil filler cap for quick draining of
the engine oil.
2) Lift-up the vehicle.
3) Drain the engine oil by loosening the engine oil
drain plug.

NOTE:
Prepare the container for draining of engine oil.

4) Tighten the engine oil drain plug after draining
engine oil.

NOTE:
Use a new drain plug gasket.

Tightening torque:

44 N

m (4.5 kgf-m, 32.5 ft-lb)

5) Using engine oil of proper quality and viscosity,
fill engine oil through the oil filler duct to the upper
level on oil level gauge. Make sure that the vehicle
is parked on a level surface when checking oil lev-
el.

Recommended oil:

Refer to “SPECIFICATION” for the recom-
mended oil. <Ref. to LU(H6DO)-2, SPECIFI-
CATION, General Description.>

Engine oil capacity (when replacing engine oil):

5.5 

2 (5.8 US qt, 4.8 Imp qt)

6) Close the engine oil filler cap.
7) Start the engine and warm it up for a time.
8) After the engine stops, recheck the oil level. If
necessary, add engine oil up to the upper level on
oil level gauge.

8) Remove the V-belt. <Ref. to ME(H6DO)-33, RE-
MOVAL, V-belt.>
9) Remove the front chain cover. <Ref. to
ME(H6DO)-45, REMOVAL, Front Chain Cover.>
10) Remove the timing chain. <Ref. to ME(H6DO)-
47, REMOVAL, Timing Chain Assembly.>
11) Remove the crank sprocket.
12) Remove the oil pump cover.

13) Remove the inner rotor and outer rotor.

B: INSTALLATION

1) Apply a coat of engine oil to the entire area of in-
ner rotor and outer rotor.

2) Fit the inner rotor with its flat surface aligned with
crankshaft, install the inner rotor, and then install
the outer rotor.
3) Install the oil pump cover.
4) Tighten the bolts in the numerical order as
shown in the figure.

CAUTION:
Ensure that the bolts are installed in correct po-
sition.

Tightening torque:

6.4 N

m (0.65 kgf-m, 4.7 ft-lb)

5) Install the crank sprocket.
6) Install the timing chain. <Ref. to ME(H6DO)-48,
INSTALLATION, Timing Chain Assembly.>
7) Install the front chain cover. <Ref. to ME(H6DO)-
45, INSTALLATION, Front Chain Cover.>
8) Install the V-belt. <Ref. to ME(H6DO)-33, IN-
STALLATION, V-belt.>
9) Install the radiator. <Ref. to CO(H6DO)-17, IN-
STALLATION, Radiator.>
10) Install the under cover.

C: INSPECTION

1. TIP CLEARANCE

Measure the tip clearance of rotors. If the clearance
exceeds the specification, replace the rotors as a
matched set.

Tip clearance:

Specification

0.04 — 0.14 mm (0.0016 — 0.0055 in)

2. CASE CLEARANCE

Measure the clearance between outer rotor and
rear chain cover rotor housing. If the clearance ex-
ceeds the specification, replace the outer rotor.

Case clearance:

Specification

0.110 — 0.175 mm (0.0043 — 0.0069 in)

3. SIDE CLEARANCE

Measure the clearance between oil pump inner ro-
tor and rear chain cover. If the clearance exceeds
the specification, replace the rotors as a matched
set.

Side clearance:

Specification

0.020 — 0.046 mm (0.0008 — 0.0018 in)

4. OIL PUMP CASE

Check the worn shaft hole, clogged oil passage,
crank and other parts for fault.
