Remove the drive
belts. |
3. |
Turn the crankshaft and align the white groove
on the crankshaft pulley with the pointer on the lower cover. (See
page EM - 9) |
4. |
Remove the timing belt. (See page EM -
23) |
5. |
Remove the oil pan and oil screen. (See page
EM - 64, 65) |
6. |
Remove the front case.

(1) |
Remove the screws(B) from the pump
housing, then separate the housing and cover(A).

|
(2) |
Remove the inner(A) and outer(B)
rotors.

| |
1. |
Install oil pump.
(1) |
Place the inner and outer rotors into
front case with the marks facing the oil pump cover
side. |
(2) |
Install the oil pump cover(A) to front
case with the 7 screws(B).
Tightenig torque
6 ~ 9Nm (60 ~ 90kgf.cm, 4.4 ~
6.6lbf.ft)
|

| |
2. |
Check that the oil pump turns
freely. |
3. |
Install the oil pump on the cylinder
block.
Place a new front case gasket on the cylinder
block. Apply engine oil to the lip of the oil pump seal. Then,
install the oil pump onto the crankshaft. When the pump is in place,
clean any excess grease off the crankshaft and check that the oil
seal lip is not distorted.

Body length
(A) : 25mm (0.98in)
(B) : 20mm (0.787in)
(C) : 38mm (1.496in)
(D) : 45mm (1.771in)
Tighttening
torque
20 ~ 27Nm (200 ~ 270kg.cm, 14.5 ~
19.8lb.ft)
| |
4. |
Apply a light coat of oil to the seal
lip. |
5. |
Using the SST(09214-33000), install the oil
seal.

|
6. |
Install the oil screen. (See page EM -
80) |
7. |
Install the oil pan. (See page EM -
81)
Clean the oil pan gasket mating
surfaces. | |
1. |
Remove the relief plunger.
Remove the plug(A), spring(B) and relief
plunger(C).

|
1. |
Inspect relief plunger.
Coat the valve with engine oil and check that
it falls smoothly into the plunger hole by its own
weight.
If it does not, replace the relief plunger. If
necessary, replace the front case. |
2. |
Inspect relief valve spring.
Inspect for distorted or broken relief valve
spring.
Standard
value
Free height : 43.8mm (1.724
in.)
Load : 3.7±0.4kg/40.1mm
(8.14±0.88lb/1.579 in.)
| |
3. |
Inspect rotor side clearance.
Using a feeler gauge and precision straight
edge, measure the clearance between the rotors and precision
straight edge.
Side clearance
|
Outer
gear
|
0.04 ~
0.09mm (0.0016 ~
0.0035in.)
|
Inner
gear
|
0.04 ~
0.085mm (0.0016 ~
0.0033in.)
|

If the side clearance is greater than maximum,
replace the rotors as a set. If necessary, replace the front
case. |
4. |
Inspect rotor tip clearance.
Using a feeler gauge, measure the tip
clearance between the inner and outer rotor tips.
Tip
clearance
0.025 ~ 0.069 mm(0.0010 ~ 0.0027
in.)
|

If the tip clearance is greater than maximum,
replace the rotor as a set. |
5. |
Inspect rotor body clearance.
Using a feeler gauge, measure the clearance
between the outer rotor and body.
Body
clearance
0.12 ~ 0.185 mm(0.0047 ~ 0.0073
in.)
|

If the body clearance is greater than maximum,
replace the rotors as a set. If necessary, replace the front
case. |
1. |
Install relief plunger.
Install relief plunger(A) and spring(B) into
the front case hole, and install the plug(A).
Tightening
torque
40 ~ 50Nm (400 ~ 500kgf.cm, 30 ~
37lbf.ft)
