Oil Strainer
Check the oil strainer for cracking and scoring. If
cracking and scoring are found, the oil strainer must be
replaced.

Reassembly
1. Install drive gear (11).
2. Install driven gear (10).
3. Install oil pump cover (9) and first, loosely tighten all
of the attaching screws. Next, tighten the attaching
screws to the specified torque.
Torque : 10 N
m (1.0 kg
m/7 lb ft)
After installation, check that the gear rotates
smoothly.
4. Install relief valve (8) and apply engine oil to the
relief valve and spring (7).
5. Install spring (7).
6. Install the plug (6).

7. Install oil pump assembly (5).
Carefully remove any oil from the cylinder body
and the pump. Apply sealant (TB–1207B o
r
equivalent) to the pump fitting face as shown in
illustration. Take care that sealant is not applied
to oil port surfaces. The oil pump assembly
must be installed within 5 minutes after sealan
t
application to prevent premature hardening o
f
sealant.
CAUTION: Do not apply an excessive amount o
f
sealant to the contact surface. Applying too much
sealant will overflow the contact surfaces. This
could cause serious damage to the engine.
Attach oil pump assembly to cylinder body.
Tighten the oil pump fixing bolts.

Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFE
R
TO THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY, OR OTHERWISE UNNEEDED SRS SYSTEM
REPAIRS.
CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, o
r
other corrosion inhibitors) on threaded fasteners o
r
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener.
When you install fasteners, use the correct
tightening sequence and specifications. Following
these instructions can help you avoid damage to
parts and systems.
