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, REFER
TO THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNECESSARY 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/GM will call out those fasteners that require a
replacement after removal. ISUZU/GM will also call
out the fasteners that require thread lockers o
r
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.

BRAKES 5C-29
ADJUSTMENT PROCEDURE OF SERVICE AND PARKING BRAKE


Stick type
All brakes are self-adjusting.
Brakes are adjusted by repeated stepping on the brake pedal.
(After stepping on the pedal and releasing it, the rear brake
auto-adjuster, produces a clicking sound.
The same operation should be repeated until the sound
disappears.)
Take the following steps after overhauling the rear brake
assembly.
1. Move the parking brake lever to its fully released position.

311R300007





























































2. Parking cable must be loosened sufficiently.
(Loosen the adjust nut and the lock nut.)
3. Repeat stepping on the brake pedal firmly and releasing it until the clicking sound can no longer be heard.
If the difference between the brake drum inside diameter o
f
the brake shoes is adjusted to be 0.5 mm, the number of
times for depressing the brake pedal can be reduced.
4. Remove the drum.
Measure the brake drum inside diameter and diameter o
f
the brake shoes.
Shoe Clearance mm (in)
0.25 - 0.40 (0.0098 - 0.0157)
If incorrect, check the brake auto-adjusting system.
5. Turn the adjuster nut so that the parking brake lever travels 10 notches when pulled up with a force 30 kg (66 lbs.).
6. Make sure there is no brake drag.

General Description
Pulling up the parking brake lever by hand will set the
parking brake. By means of a ratchet type lock, the
lever can be held in that position until it is released. The
position of the lever is transmitted through cable/leve
r
systems to the rear wheels. These parts are designed
to obtain sufficient braking force even when parking on
slopes. W hen the parking brake is set, or when the
ignition SW is in the “ON” position, the brake warning
light illuminates. The rear wheel parking brake is a
leading-trailing brake (mechanical inside expansion
type) built in the rear drum brake. Parking brake
adjustment is made through the adjusting hole (bored
through back plate). Parking brake lever stroke should
be adjusted to 8 −14 notches with 294N (30 kg / 66 lb)
(bench seat) or 6 −9 notches with 294N (30 kg / 66 lb)
(bucket seat). Refer to “Parking Brake Adjustment” in
this section.

Engine Serial Number
The engine number is stamped on the rear left hand side
of the cylinder body.
The engine number is stamped in the plate in front of the
engine room as well.


AIR CLEANER
Element cleaning procedures will vary according to the
condition of the element.

Dust Fouled Element (Except wet type element)
Rotate the element with your hand while applying
compressed air to the inside of the element. This will blow
the dust free.
Compressed air pressure kPa (kg/cm

392 – 490 (4 – 5/57 – 71)


LUBRICATING SYSTEM
Main Oil Filter (Cartridge Type Paper Element)
Replacement Procedure
1. Drain the engine oil.
2. Retighten the drain plug.
3. Loosen the used oil filter by turning it counterclockwise with a filter wrench.

4. Clean the oil cooler fitting face. This will allow the new oil filter to seat properly.
5. Apply a light coat of engine oil to the filter O-ring.
6. Turn in the new oil filter until the filter O-ring is fitted against the sealing face.
7. Use the filter wrench to turn in the filter an additional 2/3 turns.
Filter W rench: 5-8840-0200-0
8. Check the engine oil level and replenish to the specified level if required.

6A – 36 ENGINE MECHANICAL
GENERAL DESCRIPTION









RTW 46AMF000401

The 4J series automotive diesel engine has special designed combustion chambers in the piston. This design
provides superior fuel economy over a wide range of driving conditions.
Auto-thermatic pistons with cast steel struts are used to reduce thermal expansion and resulting engine noise when
the engine is cold.
Chrome plated dry type cylinder liners provide the highest durability.
The laminated steel sheet cylinder head gasket is very durable and, to increase the head gasket reliability.
The crankshaft has been tufftrided to provide a longer service life. Because the crankshaft is tufftrided, it cannot be
reground.
The 4JA1T(L) engine is equipped with the BOSCH VE-Type distributor injection pump.
The 4JH1TC and 4JA1TC engine is equipped with the BOSCH VP44-Type distributor injection pump.
The engine is turbocharger equipped.
