Service Precaution
WARNING: IF SO EQUIPPED WITH 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, REFER 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, or other
corrosion inhibitors) on threaded fasteners or
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.

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 Nꞏm (1.0 Kgꞏm/89 lb in)
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).
Torque : 8 Nꞏm (0.8 Kgꞏm/69 lb in)
051RS007
7. Install oil pump assembly (5).
Carefully remove any oil from the cylinder body and
the pump. Apply sealant (TB–1207B or 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 sealant application before the sealant
hardens.
CAUTION: Do not apply an excessive amount of
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.
Torque : 25 Nꞏm (2.5 Kgꞏm/18 lbꞏft)
